Job description
Quality EngineeringSDETCI/CDTesting InfrastructurePerformance-sensitive Systems
Overview
OneChronos is building the bazaar for agentic systems. They are looking to build a dedicated quality engineering function proactively that increases engineering velocity and confidence by making testing reliable, scalable, and easy to use across the organization.
Responsibilities
- Design, build, and maintain automated test frameworks and testing infrastructure across our trading platform, covering correctness, performance, and reliability.
- Develop tooling that enables engineering teams to test their own code more effectively, without creating bottlenecks.
- Define test strategies for new features and system changes in partnership with engineering, SRE, and DevOps teams.
- Build and own CI/CD pipeline integrations that gate deployments on meaningful quality signals.
- Build testing infrastructure and validation tooling that surfaces regressions and correctness issues before they reach production.
- Investigate test failures, quality gaps, and escaped defects, driving structural improvements to prevent recurrence.
- Participate in design and architecture reviews to identify testability gaps early.
Qualifications
- You write production-quality code and treat test infrastructure the same way -- not as scaffolding, but as software that needs to be maintained and improved.
- You have strong experience with test automation frameworks, testing infrastructure, and developer tooling, and have built or meaningfully extended one from scratch.
- You're fluent in at least one systems-oriented language (Rust, C++, Go, or Java) and at home in Python for scripting and tooling.
- You have worked in low-latency, high-throughput, or otherwise performance-sensitive environments and understand what it means to test at that layer.
- You think in edge cases. You're the person on the team who asks "but what happens if..."
- You work fluidly across organizational lines -- with SRE on reliability, with DevOps on deployment pipelines, with product engineers on correctness.
Nice to have
- Financial markets or trading systems experience is a plus, not a requirement. Curiosity about the domain is.
