QA Auto SDET

Were building a trading platform in Rust that trades on crypto and traditional exchanges around the world. Real orders and money flow through it and the cost of mistakes can be high. We run as a single product team: SDETs and core developers share the same backlog. Were looking for an engineer who would write automated tests and dig into the root cause of failures in a distributed system.

Key Responsibilities

• Design and write end-to-end automated tests for trading logic against real exchanges (Kotlin JUnit 5 Gradle gRPC ClickHouse) covering protocols like REST WebSocket FIX and binary SBE.
• Investigate incidents and test failures to root cause across logs ClickHouse data Rust platform code and exchange behavior working alongside AI agents that surface data and hypotheses.
• Validate releases by triaging large-scale test runs across dozens of exchanges filing well-evidenced bugs and stabilizing flaky tests.
• Build and maintain test infrastructure and tooling: fault-injection via an in-house MITM proxy test trading bots in Python and supporting Kotlin services (environments configs integrations).
• Maintain CI and test environments and track automation metrics to guide quality decisions.

Qualifications :

• 3 years in test automation or backend development in Kotlin/Java (or another strongly typed language with willingness to move to Kotlin).
• Strong SQL and experience with analytical databases at scale (ClickHouse is a plus).
• Practical understanding of REST and WebSocket; FIX or binary protocol experience is a plus along with the ability to read raw messages.
• gRPC/protobuf Docker and pipelines in GitLab CI / Jenkins.
• Linux administration: deployment systemd networking diagnostics over SSH on test environments.
• Observability: Grafana Loki/Prometheus or similar.
• Daily use of agentic AI tools (Claude Code Cursor Codex): delegating tasks writing your own prompts/skills connecting tools via MCP and a critical eye toward model output.
• Ability to independently navigate someone elses codebase and find the fix or the bug.

Nice to Have

• Experience in trading exchange integrations or fintech; understanding of market microstructure (order books TIF post-only funding margin).
• Rust or willingness to learn it: youll regularly need to read platform code and write tests in it; well help you ramp up.
• Python for test bots and scripting.
• Experience with mocking/proxy tools for traffic interception (Ktor Netty mitmproxy WireMock).
• Ansible and test-environment maintenance.
• Experience with multi-agent systems: orchestration verifying agent output knowledge bases.
