Staff Software Engineer, Workflows Platform

About the Role

Key Responsibilities

• Lead the development and enhancement of Lumos's event-driven notifications and workflow orchestration systems, ensuring they are scalable, extensible, and reliable across core identity governance features like access reviews and JIT approvals.
• Own and evolve the core architecture for multi-channel messaging, including delivery routing, retry strategies, escalation paths, and message templating with support for localization and personalization.
• Partner with product and engineering teams to design developer-friendly APIs and contracts for triggering, previewing, and managing user-facing messages and workflow states.
• Implement infrastructure and tooling to support observability, auditing, and delivery guarantees, enabling teams to confidently build on top of the messaging and workflow layers.
• Collaborate with platform and infra teams to ensure seamless integration with identity workflows, system events, and service boundaries—prioritizing fault tolerance, idempotency, and high throughput.
• Build and maintain internal tooling, CLIs, and reusable abstractions that empower other engineers to quickly compose, test, and deploy communication workflows without deep platform knowledge.
• Drive systemic improvements in workflow lifecycle management, including support for delayed tasks, time-based escalations, approval state machines, and SLA-bound execution paths.

Requirements

• 5+ years of experience as a backend or platform engineer, with direct experience building event-driven systems, workflow orchestration, or notifications infrastructure.
• Deep knowledge of asynchronous architectures, including message queues, state machines, and tools like Celery, Kafka, Temporal, or Step Functions.
• Strong backend development skills in Python, Go, or TypeScript, with a focus on clean API design, testability, and observability.
• Hands-on experience building multi-channel messaging systems (Slack, email, in-app), including support for templating, delivery retries, and channel fallbacks.
• Familiarity with compliance and governance use cases (e.g., audit trails, access reviews, escalation policies) and how workflows support visibility and traceability at scale.
• A track record of designing developer platforms, internal tools, or infrastructure that improves velocity, reliability, and reusability across teams.

Nice to Have

• Experience with designing developer platforms and internal tools.
• Knowledge of compliance and governance workflows related to visibility and traceability.

Qualifications

• Experience as a backend or platform engineer with a focus on event-driven systems and workflow orchestration.

Benefits & Perks

• Competitive pay range of $190,000 - $240,000.
