Lead Platform Engineer

Lead platform engineering for a scientific data infrastructure team building a foundational platform that turns diverse laboratory data into a unified, queryable knowledge base. You will own its architecture, security, and scale while establishing engineering practices and helping grow the team.

• Set the architectural direction and build production ingestion pipelines, APIs, microservices, and storage layers that normalize heterogeneous data while preserving provenance.

• Operate knowledge graphs and vector search systems to support hybrid symbolic and semantic retrieval for agentic workloads.

• Build high-concurrency services in Go and Python, including controlled write boundaries and isolated execution environments.

• Design security controls for service authentication, tenant isolation, secrets, encryption, and zero-trust access.

• Own Kubernetes-based cloud infrastructure, infrastructure as code, CI/CD, observability, SLOs, and internal developer workflows.

• Set engineering standards through architecture reviews, code reviews, mentoring, and team building.

• Partner with company leadership on engineering hiring and platform team growth.

On-site in San Francisco, United States, five days per week. Relocation assistance is available.

• At least 5 years of platform or infrastructure engineering experience, with a track record building and operating production backend infrastructure, data platforms, or distributed systems.

• Strong hands-on experience with Kubernetes, Terraform, Ansible, and modern CI/CD systems, alongside dedicated infrastructure engineering experience.

• Experience designing ingestion for messy, multi-source data, including schema harmonization and entity resolution.

• Proficiency in Go and Python or FastAPI, and familiarity with TypeDB/TypeQL, Qdrant, GitHub Actions, OpenTelemetry, and Prometheus.

• Experience establishing security boundaries and engineering rigor for production platforms; biotech data experience and SOC 2 or similar compliance experience are beneficial.

Base salary: $220,000 to $300,000 annually. Visa sponsorship or transfer is not available.
