Senior SDET

We're helping FereAI, an AI startup that has raised $2.5M, hire a Senior SDET. If you're selected, you will be working directly with them.

About FereAI

We are a fast-growing startup at the intersection of blockchain and artificial intelligence, building next-generation tools for decentralized finance, trading agents, and intelligent data-driven systems. Our team blends expertise in crypto protocols, AI modeling, and high-performance engineering to create products that redefine how people interact with financial markets.

Role Overview

As an SDET, you will be responsible for designing, developing, and executing automated test frameworks to ensure the performance, security, and reliability of our products. You will work closely with our developers, AI researchers, and blockchain engineers to validate features, simulate real-world trading scenarios, and maintain high-quality releases.

This is not just a QA role — you'll be writing production-grade code, contributing to CI/CD pipelines, and building automated testing solutions that help us ship faster without compromising stability.

Key Responsibilities

- Automation Development: Design, implement, and maintain automated test frameworks for backend, frontend, APIs, and blockchain interactions.

- Blockchain Testing: Simulate on-chain transactions, wallet interactions, and smart contract behavior for EVM-compatible chains and/or Solana.

- AI System Validation: Test AI-driven decision-making flows, ensuring correctness, performance, and resilience in production environments.

- Performance & Load Testing: Stress-test systems handling large datasets, market data feeds, and high-throughput API calls.

- Security & Reliability: Implement tests for authentication, data integrity, rate-limiting, and vulnerability detection.

- Collaboration: Work closely with developers to ensure testability, participate in code reviews, and advocate for best engineering practices.

- CI/CD Integration: Maintain test suites in the build pipeline, ensuring automated regression testing on every commit.

Required Skills & Experience

- Programming Skills: Proficiency in Python and/or JavaScript/TypeScript for automation.

- Test Frameworks: Experience with PyTest, Playwright, Cypress, Jest, or equivalent.

- API Testing: Strong experience testing REST and WebSocket APIs; familiarity with tools like Postman, Newman, or k6.

- Blockchain Knowledge: Understanding of crypto wallets, blockchain transactions, RPC calls, and smart contract testing (e.g., Hardhat, Foundry, Anchor).

- CI/CD: Hands-on with GitHub Actions, GitLab CI, or similar pipelines.

- Databases: Experience with SQL/NoSQL databases, preferably PostgreSQL and/or Redis.

- Performance Testing: Familiarity with load testing and benchmarking tools.

- Version Control: Proficient with Git and collaborative workflows.

Nice to Have

- Experience with DeFi protocols, tokenomics, and blockchain analytics.

- Exposure to ML model testing, dataset validation, and AI explainability checks.

- Knowledge of Docker and Kubernetes for environment management.

- Security testing tools (e.g., OWASP ZAP, MythX, Slither).

- Familiarity with event-driven systems and real-time data pipelines.
