Full-Stack Platform Engineer (QA Infrastructure & Web3)

We’re looking for a product-minded Full-Stack Engineer who enjoys building reliable systems that improve how technical teams evaluate, verify, and hire software quality talent.

This role goes beyond building dashboards. You’ll help shape the infrastructure behind assessment delivery, candidate workflows, verification systems, and next-generation credentialing features powered by Web3 technologies.

You’ll work closely with product, QA specialists, and platform engineers to create scalable tools that support thousands of technical evaluations and hiring decisions.

What You’ll Build

Develop scalable backend services for assessments, candidate workflows, scoring pipelines, and employer dashboards
Build responsive platform features using Next.js and modern React patterns
Design APIs for assessment engines, reporting systems, and external integrations
Architect secure data models for candidate evaluations, interview records, and credential verification
Improve platform reliability, performance, and developer experience
Integrate decentralized identity and wallet-based verification systems for future credentialing initiatives
Collaborate with QA experts to build tools that reflect real-world testing and engineering practices

Nice to Have

Experience with Ethers.js, Solidity, or wallet authentication
Familiarity with online assessment platforms, hiring systems, or QA tooling
