Senior Software Engineer

Who You Are

You have run Temporal in production — not just written workflows on top of it. You've operated a self-hosted cluster yourself, configured and maintained the datastores it depends on, and reasoned about retries, idempotency, and partial failure under real load. You've been the person other teams escalate to when something breaks. You think in terms of guarantees, and you can say concretely what teams building on a shared platform should be able to assume, and how you'd prove the platform is holding up its end.

You've also led a technical migration, infrastructure consolidation, or platform re-architecture across multiple stakeholder teams — sequencing risk, owning the decision record, and driving it to completion.

This is a senior individual contributor role on Shared Services, the team that owns and operates platform shared capabilities across Justworks engineering, so product teams can build on reliable, well-run foundations without owning that complexity themselves. You would be the team's de facto Temporal tech lead and its long-term technical authority on the platform.

The role spans both halves of platform engineering: operating and hardening a live system other teams depend on today, and building the scaffolding, conventions, and documentation that make it straightforward to build on tomorrow. You'll be hands-on with reliability and migration work, and you'll help shape what the platform becomes as more teams adopt it.

What You Will Work On

• Harden the shared Temporal cluster for multi-tenant readiness — capacity modeling, namespace isolation, and admission control
• Define the service promise: SLOs for Temporal-backed services, and alerting trustworthy enough that every page is worth waking someone for
• Build the golden paths and conventions that let other teams build workflows on the shared platform safely, with less hand-holding over time
• Enable multi-cluster availability, so tenant workloads keep running through a cluster or regional failure
• Own capacity and cost efficiency as the shared platform scales to more tenant teams and workflow volume
• Partner with tenant teams on workflow design, idempotency, and safe retry patterns as they onboard
• Rotate on the shared platform's on-call schedule — incident response, root-causing production issues, writing postmortems, and continuously tuning alerts and SLOs

How You Will Do Your Work

Good judgment — the exercise of critical thinking, analyzing and assessing problems and implications, identifying patterns, making connections of underlying issues, understanding risks and developing mitigation strategies, and taking ownership of the outcome.

Resourcefulness — taking a can-do approach, even in the face of obstacles and constraints by assessing what's in front of you and effectively and efficiently optimizing what you have, whether it's working on something new or thinking about how to do something better.

Teamwork and communication — putting our collective best together through documentation, collaboration, relationship-building, listening, empathy, recruiting, and evangelism.

Influence and leadership — fostering a community of knowledge-sharing, collaboration, mentorship, and forward-thinking.

Skills and knowledge — the capacity to actively learn and apply specific domain knowledge, know-how, and best practices to continually enhance and improve.

Qualifications

• 5+ years of professional software engineering experience
• 2+ years of hands-on, production experience operating self-hosted Temporal — running the cluster itself, not only writing workflows against one. This is a hard requirement, not a nice-to-have: experience with another workflow orchestrator does not substitute, and Temporal Cloud alone does not meet the self-host requirement
• Experience operating a distributed system in production at scale — retries, idempotency, partial failure, and the datastores and storage configuration it depends on
• Operational depth in Temporal internals and cluster administration — how the cluster is configured, maintained, and tuned, and how its constraints shape workflow design
• Experience securing and troubleshooting service-to-service communication between clients, workers, and the cluster
• Experience leading a technical migration or infrastructure consolidation across multiple stakeholder teams
• Experience defining SLOs and alerting for a platform-level service, including per-namespace / per-tenant observability and routing problems to the owning team
• Experience with Kubernetes and container orchestration in production
• Strong Golang proficiency plus at least one additional language

Nice to Have

These are the parts of the profile we consider coachable — hands-on Temporal depth matters more than any of them:

• A specific language beyond Go
• A particular cloud or Kubernetes flavor
• A prior formal "migration lead" title — someone with deep Temporal chops can grow into leading the migration without that exact label on a resume

Technologies

• Orchestration: Temporal, self-hosted (primary focus)
• Infrastructure: Kubernetes, containers
• Languages: Go (primary), plus at least one more — whatever fits the problem
• Service communication: gRPC, TLS/mTLS

The base wage range for this position based in our New York City Office is targeted at $188,000.00 - $242,000.00 per year.
