Senior Platform Engineer

The Role

We're hiring a founding platform engineer. Brellium audits clinical notes against millions of criteria a day, with AI pipelines processing billions of tokens. You'll be the first person whose full-time job is scaling towards a highly available production environment by making our infrastructure reliable and observable, defining the patterns others build on, and making every engineer more effective in their work.

This is a hands-on senior IC role reporting directly to the VP of Engineering. You'll set this function's roadmap in collaboration with engineering leadership.

What You'll Do

• Manage and scale infrastructure that runs audits on clinical notes across millions of criteria daily
• Define and support infrastructure patterns that can improve latency (e.g. making audits real time), reliability, and cost effectiveness
• Improve developer productivity through CI/CD and local / testing environments
• Simplify observability and drive key reliability metrics across all of our services, including AI pipelines that process billions of tokens daily
• Manage our infrastructure and developer tooling spend
• Steward our security posture (e.g. SOC 2, HIPAA compliance)
• Consolidate SSO, identity, device management, and access controls across internal tools

You Might Be a Fit If

• You have owned the infrastructure / platform function somewhere
• You have informed opinions about infrastructure and collaborate with product engineers to find right-sized solutions
• You understand product engineering work to a high degree
• You measure your work by whether other engineers actually use it
• You'd rather ship something narrow in two weeks than complete in two months
• You are used to the blurred lines at a startup and are biased towards taking ownership
• You are experienced working in an environment with a high degree of autonomy

Required Skills

• 5+ years where platform was your primary work
• Built production infrastructure at an early-stage startup
• Depth in AWS and infrastructure-as-code. Our tech stack includes AWS, Vercel, Azure Foundry, Claude Platform, OpenAI Platform, Gemini, and Clickhouse
• You know how to write production-level code. Our applications are written in Python and Typescript
• You have driven towards a target number for a cloud bill
• You have managed audits for software compliance (e.g. SOC 2)

Nice to Have

• Healthcare or another regulated industry that includes sensitive-data handling
• Experience with LLM infrastructure: inference cost management, gateways (e.g. Bifrost), tracing and evals (e.g. Langfuse)
• Rolled out an identity provider like Okta
• Mentored engineers or led a small team
