Proofpoint

Role Description 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. What You’ll Own - 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. What Success Looks Like - You quickly become one of the people others trust for the hardest technical questions. - You can read unfamiliar parts of the codebase, understand the domain model, and make safe changes without needing perfect documentation. - You ship pragmatic, well-tested code while also improving the underlying system design. - You help the team move faster without creating avoidable operational risk. - You make ambiguous projects feel tractable by decomposing them into clear technical decisions. - You balance product urgency, customer needs, engineering quality, and long-term maintainability. - You are comfortable working close to production and close to customers when needed. Technical Environment - Python 3.12, Pydantic, psycopg/Postgres, SQL, async job systems, AWS, SQS/Lambda-style orchestration, Docker/local mock environments. - Shared platform models for accounts, feeds, events, jobs, schedules, agents, investigations, decisions, archives, and integrations. - Capture services organized around API clients, auth flows, data normalization, sync orchestration, retries, and backfills. - AI systems using structured LLM outputs, evals, token budgets, embeddings/vector search, vLLM/local models, and agent workflows. - React/TypeScript UI surfaces for settings, agent runs, investigations, decisions, and operational workflows. Qualifications - 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. Benefits - Competitive compensation - Comprehensive benefits - Career success on your terms - Flexible work environment - Annual wellness and community outreach days - Always on recognition for your contributions - Global collaboration and networking opportunities How to Apply Interested?
