Staff Software Engineer, Test Systems & Tooling

What You'll Do

• Build production-like test environments: Design and evolve tooling that makes it easy for engineers to spin up test cells that resemble production topology, configuration, and behavior, in partnership with Cloud/Infrastructure.

• Enable production-representative workloads: Build capabilities for workload generation, multi-tenant testing, stress/load testing, and (where appropriate) traffic replay or replay-like systems to reproduce production behaviors in controlled environments.

• Make failure-mode testing repeatable: Create tooling for injecting and validating failure conditions (latency, dependency faults, resource exhaustion, degraded-state recovery, and region-level failure scenarios) so we test them deliberately—not just learn from production.

• Drive system-level test coverage: Identify high-impact system-level scenarios that are currently hard to test, and implement (or partner with the right teams to implement) repeatable coverage that’s incorporated into continuous and/or release validation.

• Build shared frameworks and paved paths: Provide opinionated libraries, harnesses, and patterns that make it easier for product teams to write high-quality system and integration tests consistently.

• Raise the technical bar through leadership: Mentor engineers and influence testing strategy across the org through design docs, code reviews, and cross-team collaboration.

• Partner across Engineering: Work closely with Reliability and Release Engineering to turn incident learnings into durable pre-production test coverage and to integrate validations into the release pipeline.

• What You'll Bring

• Strong software engineering fundamentals and experience building and operating production-quality systems (platforms, infrastructure, developer tooling, or distributed systems).

• Demonstrated technical leadership: leading ambiguous, cross-team initiatives; driving alignment; and delivering durable systems that other teams rely on.

• Experience designing for observability, debuggability, and operational readiness (metrics, logs, tracing, safe rollouts, and failure analysis).

• Comfort working across organizational boundaries—collaborating with Cloud/Infrastructure, Reliability, Release Engineering, and product teams to land outcomes.

• Strong written communication skills (design docs, testing strategy proposals, and documentation that scales adoption).

• Nice to Haves

• Experience with chaos engineering, fault injection, workload replay/shadowing, performance testing, or multi-tenant test strategy.

• Experience building internal platforms used broadly across an engineering org (paved roads, self-serve environments, shared frameworks).

• Familiarity with measuring engineering/system outcomes (e.g., signal quality, coverage gaps closed, incident-to-coverage time, adoption).

• How We Work

• Temporal is remote-first. Most roles are remote in-country, some

• are remote within a region, and a few teams have an in-office hub.

• Occasional travel supports onboarding and team gatherings, and

• some teams share an on-call rotation. See how we work →

• Benefits & Perks

• Temporal offers competitive benefits, equity, flexible time off,

• and support for learning, wellness, and your home office. See everything we offer →
