Lead Platform Engineer

ABOUT THE ROLE As the senior engineering anchor for a data infrastructure and analytics platform, you will lead the architecture and operation of systems that turn diverse scientific data into a reliable, queryable knowledge base. You will shape the platform's technical direction, security, and growth while helping establish strong engineering practices. WHAT YOU'LL DO - Own the architecture, delivery, security, and scaling of the core data and execution platform. - Build and operate ingestion pipelines, APIs, microservices, and storage that organize heterogeneous data while maintaining provenance. - Manage knowledge graph and vector search systems to support combined symbolic and semantic retrieval. - Develop high-concurrency services in Go and Python, with controlled agent write access and isolated execution environments. - Define security boundaries covering service authentication, tenant isolation, secrets, encryption, and zero-trust practices. - Own cloud infrastructure, CI/CD, and observability, and establish service-level objectives and developer workflows. - Set engineering standards through architecture guidance, code reviews, mentorship, and team building. - Partner with company leadership on team design, candidate interviews, and platform engineering recruitment. WHAT WE'RE LOOKING FOR - 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. - Dedicated infrastructure engineering experience in addition to software engineering. - Strong experience with Kubernetes, Terraform, Ansible, and modern CI/CD systems. - Experience designing ingestion for messy, multi-source data, including schema harmonization and entity resolution. - Proficiency in Go, Python, FastAPI, TypeDB and TypeQL, Qdrant, GitHub Actions, OpenTelemetry, and Prometheus. - Experience guiding early-stage infrastructure toward greater reliability and engineering rigor; familiarity with computational biology, biotech data systems, or compliance frameworks such as SOC 2 is a plus.
