Sr. Software Engineer in Test, FinTech

Description:
As a Senior Software Engineer in Test (SDET) on the FinTech Team, you will engineer the automated defense systems that protect Tesla’s financial backbone. We are moving beyond traditional static test scripts. Your mission is to architect intelligent, self-healing automation frameworks completely in Python that leverage Generative AI to dynamically build, validate, and inject test scenarios directly into our CI/CD pipelines. You will work at the intersection of quality, DevOps, and AI, building tools that safeguard payments, reconciliation, billing, and invoicing systems handling billions in revenue. You will treat test infrastructure as production software, designing autonomous agents that analyze code changes, generate coverage for complex financial logic, and ensure 99.99% reliability without slowing down the release velocity.
Locations: Fremont, CA or Bellevue, WA

Responsibilities:
Architect and build next-generation, object-oriented test automation frameworks using Python that treat infrastructure-as-code and integrate deeply with backend microservices
Engineer AI-driven tools that utilize LLMs to analyze pull requests, automatically generate Python-based unit and integration tests for financial logic, and dynamically inject them into the CI/CD pipeline
Develop "self-healing" test suites that adapt to UI or API schema changes automatically, reducing maintenance overhead for the engineering team
Validate the integrity of complex FinTech flows—including multi-party payments, ledger reconciliation, and automated invoicing—ensuring mathematical accuracy across distributed systems
Build custom CI/CD plugins and orchestration workflows (e.g., in Jenkins or Argo) that intelligently select and execute tests based on the scope of code changes
Write high-performance Python code to simulate massive transaction loads, stress-testing our financial platforms to ensure stability during peak global events
Collaborate with backend engineers to design testable architectures and promote a culture where quality is baked into the code from the first commit

Requirements:
Degree in Computer Science, or equivalent experience with 5+ years of hands-on software engineering experience

Expert-level coding proficiency in Python
You are a developer who focuses on quality and can write production-grade Python code, not just simple scripts
Proven experience integrating AI/LLMs (OpenAI, LangChain, etc.) into developer workflows or testing tools (e.g., using AI for test generation or log analysis)
Deep understanding of CI/CD internals (Jenkins, GitHub Actions, Argo workflows) with the ability to write custom pipelines and dynamic build scripts
Expertise in testing backend microservices (REST, gRPC) and distributed systems, preferably within a FinTech context (Payments, Billing, Ledgering)
Experience with containerization (Docker, Kubernetes) to spin up ephemeral test environments on demand
A "shift-left" mindset with a track record of building tools that empower developers to ship faster and more confidently
