Automation & Performance Engineer | 12 weeks+ (575)

About the opportunity A full-time engineer d rive cross-functional software and engineering delivery across two parallel workstreams to keep projects . On the control plane you help automate the adversarial and functional suites into repeatable CI runs; on the platform you design load tests for the high-traffic paths.

The through-line is engineering rigor applied to making tests fast, repeatable, and meaningful. About our client Our client is preparing two AI-driven platforms for enterprise readiness, with a focus on security, correctness, and financial integrity ahead of a production launch . What you'll do Build and maintain automated test suites for the team, integrated with the freeze-audit CI gate.

Design and run performance and load tests to the team intercept latency and throughput — the layer cannot become a bottleneck. Design and run load tests high-traffic paths (as a later pass in that workstream). Build test harnesses and data generators that respect each platform's gated identity and account rules.

Report performance findings and bottlenecks with clear evidence and reproduction steps. What you bring (must-haves) Strong test-automation experience (Python; JS/TS useful for the team). Hands-on performance / load testing (k6, Locust, JMeter, Gatling, or similar) with sound methodology.

CI/CD fluency (GitHub Actions or equivalent) and Docker. Ability to reason about latency and throughput in a service that sits in the request path. Clear written English and evidence-based reporting.

Bonus points for (nice-to-haves) Experience load-testing payment or transactional systems. Familiarity with Render, Vercel, and Supabase. Observability / profiling background.
