How Nindar Builds Cross-Border Engineering Shortlists for Web3 Products Moving Into Production

A Web3 product may begin with a small team focused on smart contracts, blockchain integration and an early user experience. As the product moves toward production, the hiring requirement can become more complex.

The company may need engineers who can support smart contracts, APIs, data flows, blockchain nodes, cloud infrastructure, software releases and production monitoring. Finding candidates with the correct combination of experience can be difficult - particularly when the vacancy is described only as “Web3 engineer.”

The Specific Hiring Problem Facing Web3 Companies

A prototype proves that an idea can work. A production product needs to continue working when real users, transactions and external systems are involved.

That difference affects the people a company needs.

Smart contracts are only one component of many Web3 applications. Ethereum’s developer documentation covers contracts alongside nodes, clients, network connections, development frameworks, APIs and other parts of the technology stack.

A production Web3 product may therefore involve responsibilities across three connected areas:

• Blockchain engineering: Smart-contract development, blockchain integration, transaction logic and protocol interaction
• Backend engineering: APIs, databases, authentication, off-chain services, indexing and connections with external systems
• DevOps and reliability: Cloud infrastructure, deployment automation, system monitoring, incident response and service availability

These responsibilities do not always belong to three separate positions. One experienced engineer may cover more than one area, particularly in a smaller company. However, employers still need to know which capabilities must be owned.

A broad vacancy can attract candidates with very different backgrounds. One applicant may have written smart contracts but never supported a live product. Another may be a strong backend engineer with limited blockchain experience. A third may understand cloud infrastructure but not the operational requirements of decentralised applications.

The hiring problem is therefore not simply finding more Web3 applicants. It is identifying professionals whose experience matches the product’s actual production responsibilities.

How Nindar Can Help Build the Right Engineering Shortlist

Nindar can support this hiring challenge through a structured recruitment process designed around the employer’s requirements.

The process begins by clarifying the work, not by searching for a fashionable job title.

1. Clarifying the Required Candidate Profiles

Before launching the search, Nindar works with the employer to understand the company, vacancy, essential skills, seniority, location requirements and hiring timeline.

For a Web3 product moving into production, this may involve clarifying questions such as:

• Which blockchain networks does the product use?
• Will the engineer write or maintain smart contracts?
• Which backend services connect to the blockchain?
• Will the product operate its own nodes or use external providers?
• Who owns deployment, monitoring and incident response?
• Which systems contain sensitive data or privileged access?
• Does the company need one versatile engineer or several specialists?
• Which skills are essential on the first day?
• Which knowledge can be developed after hiring?

These questions help separate the roles correctly.

A blockchain engineer may need strong smart-contract or protocol experience. A backend engineer may need to build reliable APIs and services around blockchain activity. A DevOps or Site Reliability Engineer may need to manage cloud environments, deployment pipelines and monitoring.

Nindar does not define the client’s technical architecture. Instead, it helps translate the company’s agreed technical requirements into realistic candidate profiles.

2. Separating Essential Experience From Preferred Experience

Web3 vacancies can become unnecessarily broad when every possible technology is treated as mandatory.

A job description may request experience across Solidity, Rust, Go, TypeScript, cloud infrastructure, Kubernetes, smart-contract security, blockchain nodes, databases and several networks. Few candidates will bring equal depth across every area.

Nindar can help employers distinguish between:

• Experience directly connected to the role
• Knowledge that supports the wider team
• Skills that can be learned after joining
• Responsibilities already covered internally
• Specialist knowledge that may require a separate hire

This distinction can make the search more practical.

For example, a backend engineer supporting a decentralised application may not need to be a smart-contract auditor. However, the candidate may need to understand transaction states, wallet authentication, blockchain data and the limitations of external node providers.

Likewise, a DevOps engineer may not write Solidity, but they may need experience supporting distributed systems, managing access controls and responding to production incidents.

The objective is not to lower the hiring standard. It is to connect each requirement to the work the candidate will actually perform.

3. Mapping Relevant Cross-Border Talent Markets

Once the profiles are clear, Nindar can map the relevant talent market before or during the search.

Through Talent Mapping and Market Intelligence, Nindar can help employers examine:

• Where relevant professionals may be located
• How available the required combination of skills appears to be
• Which companies employ comparable talent
• How competitor engineering teams may be structured
• Likely compensation expectations
• Whether the proposed role is realistic within the target market

This is useful when the local candidate pool is limited or when the company is deciding where to focus an international search.

Nindar’s cross-border talent hubs include China, Vietnam and Europe. However, every region should not automatically be included in every search. The target market should reflect the required skills, seniority, working arrangements, language needs and hiring conditions.

The purpose of talent mapping is to give the employer a more evidence-based search plan - not to assume that one country is always the correct source of talent.

4. Running a Targeted Cross-Border Search

After the role and target markets are agreed, Nindar can run a focused search for professionals whose experience matches the brief.

Depending on the requirement, the search may include:

• Blockchain engineers
• Smart-contract developers
• Solidity engineers
• Web3 or DeFi developers
• Backend engineers
• DevOps engineers
• Site Reliability Engineers
• QA or test engineers
• Data engineers

Only the roles required by the product should be included.

A targeted search differs from collecting a large volume of applications. Nindar can approach relevant professionals across its cross-border network, including candidates who may not be actively applying through public job boards.

This can help the employer reach people whose current or previous work is closer to the production environment being built.

5. Screening for Evidence of Production Experience

Technical keywords do not show whether a candidate has supported a live product.

Nindar’s recruitment process includes structured technical screening, interviews and reference checks before candidates reach the client’s final selection process. The exact screening should reflect the vacancy.

For a blockchain engineer, relevant evidence may include:

• Contracts or blockchain integrations they personally developed
• Testing methods used before deployment
• How permissions and upgrade mechanisms were handled
• How the candidate responded to defects or unexpected behaviour
• Their contribution during reviews or audits
• How they monitored contracts after deployment

Ethereum’s guidance on testing smart contracts explains that testing before deployment can include unit, integration and property-based approaches. Candidates do not need to use identical tools, but they should be able to explain how they tested their own work and what risks remained.

For a backend engineer, screening may examine:

• APIs and services they personally built
• How off-chain systems interacted with blockchain data
• Database and data-consistency decisions
• Authentication and permission models
• Management of failed or delayed transactions
• Monitoring and debugging in production

Ethereum applications commonly communicate with nodes through JSON-RPC interfaces. A candidate working on relevant integrations should be able to explain the systems they used and the trade-offs they encountered.

For DevOps or SRE candidates, useful evidence may include:

• Cloud environments they managed
• Deployment and rollback processes
• Monitoring and alerting
• Node or infrastructure management
• Access controls and secrets management
• Responses to production incidents
• Cooperation with development and security teams

Google Cloud describes DevOps as a combination of practices intended to improve software delivery, service reliability and shared ownership. Relevant candidates should therefore demonstrate more than familiarity with particular tools; they should show how their work supported reliable delivery and operations.

Screening cannot remove every hiring risk. It can, however, give the employer clearer evidence before committing internal engineering time to interviews.

6. Providing a Focused Shortlist

After sourcing and screening, Nindar can present a focused shortlist of candidates whose experience aligns with the agreed requirements.

Each candidate should be relevant for a clear reason. That may include:

• Experience with the required blockchain ecosystem
• Evidence of operating production software
• Relevant backend or infrastructure depth
• Appropriate seniority
• Suitable working arrangements
• Clear communication about previous responsibilities
• Alignment with the employer’s timeline and compensation range

The employer then conducts its own interviews, technical evaluation and final selection.

Nindar’s role is to improve the relevance of the candidates reaching that stage. The final hiring decision remains with the client.

For many positions, Nindar aims to provide an initial vetted shortlist within 48 hours of the kickoff call. Specialist searches may require additional time, depending on the role and available talent market.

Selecting the Right Nindar Recruitment Model

The appropriate recruitment service depends on the scale of the hiring requirement.

Talent Recruitment for Defined Specialist Vacancies

Nindar Talent Recruitment may be suitable when a Web3 employer needs one or several clearly defined permanent hires.

This service can support:

• Requirement clarification
• Cross-border candidate sourcing
• Structured screening
• Focused shortlisting
• Coordination through interviews and offers
• Support during placement and onboarding

Nindar’s permanent recruitment uses a 15–20% success-based placement fee, payable when a hire is made. Permanent placements are also supported by a 90-day replacement guarantee.

RPO for Continuing Multi-Role Hiring

If the company needs to recruit several connected engineering positions over an extended period, Recruitment Process Outsourcing may be more appropriate.

RPO provides dedicated recruiters who can work within the employer’s hiring systems and manage sourcing, screening, scheduling and reporting across the recruitment pipeline.

It should not automatically be recommended for one vacancy. Its value is greater when the employer needs continuing recruitment capacity or coordinated multi-role hiring.

Talent Mapping Before Opening the Search

A company may also begin with a dedicated talent-mapping project when it needs market evidence before approving the recruitment campaign.

This may be useful when leaders need to compare regions, understand compensation, assess talent availability or decide whether several specialist requirements should be combined into one role.

Why the Recruitment Approach Must Match the Hiring Need

A Web3 company hiring one senior backend engineer does not need the same recruitment model as a scale-up building an entire production engineering function.

The correct response depends on the problem:

• One or several defined permanent vacancies may suit Talent Recruitment.
• Continuing multi-role hiring may justify RPO.
• Uncertainty about locations, availability or compensation may require Talent Mapping first.
• A senior leadership search may require Executive Search.

Selecting the correct approach helps keep the recruitment process proportionate to the hiring need.
