Job description

TestSprite is an AI-powered software testing platform that helps teams plan, generate, run, and debug tests automatically—speeding up releases and improving reliability. We're building the backbone that lets developers ship with confidence, and we're looking for a backend-focused engineer to help us scale.

What You'll Do

• Design, build, and operate backend services and APIs that power AI-driven test generation and execution.


• Own projects end-to-end: architecture, implementation, observability, and iterative improvements.


• Optimize data flows, queues, and storage for performance and reliability.


• Harden security, auth, and multi-tenant controls across our platform.


• Collaborate with founders and product to translate customer needs into shippable software.


• Raise the bar on code quality through reviews, testing, and documentation.

What We're Looking For

• 5+ years of professional software engineering experience (backend-heavy).


• Cloud experience required — AWS preferred (Lambda/ECS, API Gateway, DynamoDB/Postgres, S3, CloudWatch).


• Strong in one or more backend languages (Python, TypeScript/Node, Go) and modern API design (REST/GraphQL).


• Understands distributed systems, reliability, and observability (tracing, metrics, logging).


• Comfortable with containers, CI/CD, and infrastructure-as-code (Docker, Terraform/CDK, etc.).


• Communicates clearly, ships pragmatically, and enjoys fast iteration with real users.

Nice to Have

• Background in developer tools, testing frameworks (e.g., Playwright), or security-minded systems design.


• Python + TypeScript/Node


• Docker, IaC, CI/CD


• Playwright, modern observability tooling

Why TestSprite

• Meaningful ownership and impact on a product used by engineering teams.


• Tight-knit, high-agency culture with fast feedback loops.


• Competitive compensation with equity, benefits, and hardware support.


• Hybrid rhythm that balances focus time with in-person collaboration.
