Senior Engineering Manager - Test Systems & Tooling

Summary

What You'll Do

• Lead and grow the Test Systems & Tooling team: Hire, coach, and develop engineers building shared testing capabilities used across Engineering.
• Make production-like testing practical: Improve the ability for engineers to create test environments that resemble production topology, configuration, scale, and behavior—so reproducing issues and validating changes is faster and more reliable.
• Enable production-representative workload testing: Build or evolve capabilities such as workload replay, realistic workload generation, multi-tenant testing, load testing, and stress testing to surface behaviors that only emerge at scale.
• Drive failure-mode validation: Establish repeatable ways to test Temporal through real failure conditions (e.g., dependency failures, latency injection, resource exhaustion, degraded-state recovery, and regional failure scenarios).
• Create shared frameworks and guidance: Provide opinionated testing frameworks, patterns, and tooling that make it easier for product teams to write high-quality tests consistently, with visibility into test health and systemic gaps.
• Own system-level coverage outcomes: Identify critical system-level scenarios that need explicit coverage, drive them to completion (often through partner teams), and ensure they’re integrated into continuous and/or release validation.
• Collaborate across org boundaries: Partner closely with Cloud/Infrastructure, Reliability, Release Engineering, and product teams to turn production learnings into stronger pre-production detection.

What You'll Bring

• Experience managing and developing a high-performing engineering team (including direct reports), with strong coaching, feedback, and performance management skills.
• Strong technical background building or operating reliable distributed systems (or adjacent platform infrastructure) and the judgment to prioritize the failure modes that matter most.
• Track record delivering internal platforms/tooling adopted by many teams—balancing ergonomics, speed, and long-term maintainability.
• Comfort operating in ambiguous problem spaces where success depends on aligning stakeholders, clarifying ownership, and driving execution across multiple teams.
• Ability to define and drive measurable outcomes (adoption, confidence signals, reduced escaped issues, faster incident-to-coverage time), not just ship tooling.

Nice to Have

• Experience with large-scale testing practices: chaos engineering, fault injection, workload replay/shadowing, performance testing, or multi-tenant test strategy.
• Experience partnering with Release Engineering or CI/CD platform teams to institutionalize validations in pipelines.
• Familiarity with observability and incident response practices, and translating incident learnings into preventative test coverage.

Compensation

• The estimated pay range for this role is $268,000 - $351,750 depending on experience and location. 
• This role is eligible to participate in Temporal's equity plan.
