Automation & Performance Engineer | 12 weeks+ (575) at Ubiminds: You, International.
Worldwide | Sept. 10, 2026
Company: Remote First
Country: Worldwide
Type: Remote
Employment: Full-time
Description: About the opportunity A full-time engineer covering two complementary needs across both apps: test automation on Nehemiah Layer and performance/load testing on CALL-IT. On the control plane you help automate the adversarial and functional suites into repeatable CI runs; on the real-money 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 Nehemiah decision path, integrated with the freeze-audit CI gate. Design and run performance and load tests for Nehemiah intercept latency and throughput — the layer cannot become a bottleneck. Design and run load tests for CALL-IT 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 preferred for the Nehemiah side; JS/TS useful for CALL-IT). 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.
