What will you do?
As a Staff AI Software Engineer, you will:
- Design, build, and operate backend services in Python that power AI-driven products and shared capabilities.
- Build and maintain resilient service integrations across internal and external systems, handling failure modes, rate limits, and interface changes.
- Own ambiguous, end-to-end problems: from early design and architecture through implementation, rollout, and iteration in production.
- Develop and evolve LLM-backed features and agentic workflows used in production, with a focus on reliability, observability, and real-world behavior.
- Contribute to core AI platforms and enablement systems—services that your team uses directly and that other engineers can build on.
- Collaborate with product managers, researchers, and other engineers across teams to turn loosely defined AI use cases into concrete, production-ready systems.
- Help shape evaluation and quality strategies for AI-powered features, including building or extending evaluation harnesses, benchmarks, or feedback loops.
- Act as a technical leader for the work you own—making sound design decisions, coordinating with stakeholders, and contributing to design and code reviews.
- A degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
- 8+ years of experience building and shipping production backend software.
- Excellent modern Python engineering skills, with the ability to work effectively in distributed, asynchronous environments.
- Strong system design skills, including the ability to write clear design docs and solution specifications that align stakeholders and drive sound architectural decisions.
- Demonstrated ability to shepherd work from concept through production in complex, evolving environments.
- Proven experience designing and implementing integrations across multiple systems in production environments.
- Hands-on experience shipping and operating LLM- or generative-AI–backed features or services as part of larger production systems.
- Excellent communication skills and a collaborative approach in globally distributed teams.
- Experience designing or operating core platforms, internal services, or developer enablement tooling.
- Experience with applied LLM systems and context engineering, including agentic workflows, retrieval-augmented generation, or evaluation pipelines.
- Experience building and evolving service interfaces using REST, GraphQL, and/or gRPC, with an understanding of tradeoffs around performance, schema evolution, and compatibility.
- Experience with stateless and stateful backend systems (e.g., relational or NoSQL databases, caching, streaming systems).
- Experience with modern AI engineering ecosystems, such as Pydantic AI, LLM tracing and observability systems, evaluation pipelines, or MCP.
- Familiarity with MLOps or AIOps concepts and tooling (e.g., MLflow, Databricks, model gateways).
- Experience with cloud infrastructure (AWS, Azure, GCP), including effective use of managed services, and deployment tools (Docker, Kubernetes, Terraform, ArgoCD).
- Background in—or curiosity about—applying AI to cybersecurity or similarly complex, real-world domains.
You will be joining a cutting-edge company where you will tackle extraordinary challenges and work with the very best in the industry.
