Senior Principal Software Developer - IC5

We are looking for a senior staff-level engineer to design, build, and operate high-scale distributed systems and lead agentic-first development practices. This role works across product, infrastructure, data, security, and platform teams to turn ambiguous goals into durable architectures and production-quality systems. You will stay deeply hands-on while setting technical direction, mentoring engineers, and raising the engineering bar.

Responsibilities

• Lead the design, implementation, testing, and operation of high-scale distributed systems, APIs, services, data pipelines, and platform components.

• Own major initiatives end to end, from ambiguous requirements and architecture through rollout, observability, and production support.

• Architect for reliability, scalability, low latency, fault isolation, backpressure, graceful degradation, data consistency, and operational visibility.

• Raise engineering quality through automated testing, code review, CI/CD, deployment automation, incident follow-up, and documentation.

• Use agentic-first development practices to accelerate prototyping, debugging, refactoring, test generation, documentation, and delivery while maintaining human ownership.

• Build or integrate AI/agent workflows, including tool use, RAG, agent harnesses, evaluations, workflow automation, AI observability, and LLM-backed experiences.

• Apply secure-by-default and responsible-AI practices across identity, access control, secrets handling, dependency hygiene, data protection, threat modeling, and secure code review.

• Partner with product, architecture, security, operations, and peer engineering teams to translate broad goals into technical plans and tradeoff decisions.

• Mentor engineers, lead design reviews, and define standards for maintainable, supportable, production-grade software across teams. Basic Qualifications

• 10+ years of software engineering experience, including senior/staff-level ownership of production systems.

• Strong programming ability in one or more languages such as Java, Python, Go, C++, Rust, or TypeScript.

• Proven experience designing and operating distributed systems, cloud services, SaaS platforms, data systems, or infrastructure services at scale.

• Deep knowledge of system design, APIs, data modeling, concurrency, asynchronous processing, failure modes, performance analysis, and production troubleshooting.

• Experience with cloud platforms, containers, CI/CD, observability, automated testing, deployment automation, and operational readiness.

• Hands-on use of AI-assisted and agentic development tools such as ChatGPT, Claude, Copilot, Cursor, or similar tools.

• Practical experience with LLM patterns such as prompt engineering, RAG, tool use, agent frameworks, harnesses, evaluations, or workflow automation.

• Working security knowledge across identity, access control, secure coding, dependency management, data privacy, and incident-aware engineering.

• Strong communication skills, technical judgment, and ability to lead across teams without direct reporting authority. Preferred Qualifications

• Experience building high-scale, low-latency, high-availability, multi-tenant distributed systems and influencing architecture across teams.

• Experience with agentic AI platforms, LLM evaluation, AI observability, guardrails, tool orchestration, or developer productivity tooling.

• Experience in regulated, enterprise, healthcare, cloud infrastructure, data platform, or security-sensitive environments.
