Job Purpose:
BTIG's Technology Quality Management team is hiring a hands-on Software Development Engineer in Test (SDET) to generate, execute, debug, and maintain automated tests across critical workflows. Reporting to the Head of QA, you will own test suites, improve reliability, investigate failures, and provide clear quality evidence to support daily engineering decisions. You will work on a lean, hands-on team where ownership, judgment, and follow-through matter.
You will also work with and improve OpenCode-based skills and frameworks that accelerate test engineering workflows. Prior hands-on experience with terminal/TUI agentic tools applied to real test engineering is required.
Duties & Responsibilities:
- Build and maintain Playwright and TypeScript-based automated tests across UI, API, integration, and regression coverage areas
- Translate product requirements, defects, and API specifications into reliable automated test cases
- Investigate flaky or failing tests, identify root causes, and produce reproducible defect evidence
- Design and maintain OpenCode-based agent workflows for test generation, failure triage, regression selection
- Apply context engineering and cost-efficiency strategies without weakening verification quality
- Develop and maintain test data approaches, including fixtures, synthetic data, and environment-safe datasets for repeatable automation
- Integrate automation into CI/CD pipelines with reliable gating, clear failure reporting, and retained test artifacts
Requirements & Qualifications:
- 3+ years hands-on SDET experience with demonstrated ownership of automated tests across UI, API, contract, integration, and regression layers
- Strong hands-on experience with Playwright and TypeScript, including fixtures, traces, parallel execution, and CI artifact analysis
- Experience using AI-assisted development or test tools in terminal, CLI, or editor-based workflows (OpenCode, Claude Code, Codex, etc.); proven ability to critically review and correct agent-generated tests, commands, and code
- Working knowledge of agent architecture: primary/subagents, scoped tool permissions, repo memory, model routing, and human-in-the-loop review
- CI/CD integration experience (GitHub Actions, Jenkins, or equivalent)
- API testing fundamentals: REST, OpenAPI, contract testing, auth/authz boundaries, and negative-path validation
- Strong debugging discipline for test failures, flaky behavior, and application defects
- Nice to have: performance, load, or chaos engineering exposure; open-source contributions to test or agentic tooling; Financial services or regulated environment experience
