Senior Software Development Engineer in Test (SDET)

About the Role

We are building StartaleApp, a next-generation Web3 application that brings together a wide range of blockchain and DeFi functionality into a single user experience. The platform interacts with multiple blockchain networks, smart contracts, wallets, tokens, and on-chain protocols, creating complex flows that span frontend applications, backend services, blockchain infrastructure, and decentralized systems.

As a Senior Software Development Engineer in Test (SDET), you will own the engineering foundations of quality across the platform. Rather than simply writing automated tests, you will design and build the testing architecture, automation frameworks, developer tooling, CI/CD integrations, and AI-powered quality systems that enable the entire engineering organization to ship quickly and confidently.

You will work across frontend applications, backend services, blockchain integrations, smart contracts, and DeFi functionality to ensure correctness, reliability, and security across complex real-world Web3 flows.

This is a highly technical software engineering role focused on building quality systems, not performing manual testing. We are looking for engineers who enjoy building platforms, tooling, and automation that other engineers rely on every day.

Key ResponsibilitiesQuality Engineering Platform

• Design, build, and evolve the company’s quality engineering platform.
• Define testing architecture across unit, integration, contract, API, and end-to-end testing.
• Build and maintain reusable testing frameworks, shared libraries, fixtures, and developer tooling.
• Continuously improve developer experience around testing and quality engineering.

AI-powered Quality Engineering

• Design and implement AI-assisted quality engineering workflows throughout the software development lifecycle.
• Build systems that leverage LLMs for automated test generation, test maintenance, failure analysis, root cause identification, and regression detection.
• Develop internal tooling that combines traditional automation with AI to improve engineering productivity and software quality.
• Continuously evaluate emerging AI technologies and integrate them into the team’s quality engineering practices.

Test Automation & CI/CD

• Build comprehensive automated test suites covering APIs, backend services, frontend applications, blockchain interactions, and Web3 user flows.
• Integrate automated testing into CI/CD pipelines with fast feedback cycles and automated quality gates.
• Optimize test execution through parallelization, intelligent test selection, caching, and infrastructure improvements.
• Drive automation-first engineering practices across development teams.
