Staff Software Engineer
About The Position
Nuclei is looking for a Staff Software Engineer to help lead the evolution of our Capture and Intelligence platform inside Proofpoint. This person will work in a Python-first monorepo that powers communications capture, compliance workflows, event processing, AI classification, agentic investigations, and emerging decision-governance products. This is a role for someone who can operate in real production complexity: external APIs, OAuth flows, rate limits, async job orchestration, Postgres data modeling, customer-specific edge cases, LLM-powered intelligence, and enterprise-grade reliability. The ideal candidate is not just a strong coder, but a technical owner who can bring clarity to ambiguous systems and raise the quality of everyone around them.
Requirements
- 8+ years building production backend or full-stack systems, with Staff-level ownership of large or ambiguous technical areas.
- Strong Python experience, including typed code, data modeling, testing, and production debugging.
- Deep experience with relational databases, especially Postgres, schema design, query performance, migrations, and data correctness.
- Experience building distributed or asynchronous systems involving queues, workers, retries, idempotency, rate limits, and failure recovery.
- Strong API integration experience, ideally with OAuth, webhooks, pagination, throttling, vendor-specific edge cases, and long-running backfills.
Responsibilities
- Design, build, and maintain critical backend systems across capture services, shared platform models, event pipelines, async workers, APIs, and AI/intelligence workflows.
- Lead technical execution for ambiguous, high-impact projects that span multiple services or domains.
- Work directly in systems that ingest and normalize communications data from platforms like Microsoft, Slack, Zoom, Google, Bloomberg, Salesforce, Proofpoint Archive, and other enterprise sources.
- Contribute to AI-native product surfaces including LLM classification, agent runs, investigator workflows, telemetry, evaluations, and future decision-tracing capabilities.
- Improve reliability, observability, testability, and operational maturity across a fast-moving production codebase.
- Debug difficult customer and production issues involving data correctness, API behavior, async failures, scale, performance, and compliance-sensitive workflows.
- Mentor engineers through design review, code review, pairing, technical writing, and clear architectural judgment.
