Senior Software Engineer II, Enterprise Platform
About The Position
We're hiring a Senior Software Engineer II, Developer Platform to own critical systems across two areas: the enterprise lifecycle (multi-tenancy, auth, auditability) and the developer ecosystem (public APIs, SDKs, MCPs, and bring-your-own integrations) that let customers and developers build on Lila. Our internal scientists across both physical and life sciences are first-class customers of this platform, so you'll build for them as directly as for external developers. This is a high-autonomy role: you'll own outcomes, ship regularly, and operate with technical judgment about tradeoffs.
Requirements
- 7+ years of backend software engineering, with meaningful experience in APIs, backend services, or platform infrastructure.
- Strong expertise in one or more of: API design and versioning, multi-tenancy, authentication/authorization, or backend services at scale.
- Solid in Python (FastAPI), Kubernetes, AWS, databases (SQL or document).
- You care about developer experience — you know what makes APIs easy or painful. You write clear errors and think about backward compatibility.
- Ship working code regularly. Debug production issues. Own systems end-to-end.
- Work well across teams you'll have real overlap with infra, data, apps, and science teams.
- Communicate tradeoffs clearly and make decisions under ambiguity.
Nice To Haves
- Built or maintained multi-tenant SaaS platforms with audit, compliance, or isolation requirements (SOC 2, HIPAA, GxP, FedRAMP).
- Shipped public developer platforms, APIs, or SDKs and understand what makes integrations sticky.
- Familiarity with MCP, OpenAPI, or OIDC/OAuth 2.0.
- Worked on tenant isolation patterns (row-level security, schema per tenant, search-path isolation).
- Experience with policy-based authorization (OPA) or externalized authz.
Responsibilities
- Build secure tenant isolation, authentication, authorization, and audit across customer organizations.
- Implement the access boundaries and isolation guarantees that enterprise and regulated (e.g. GxP, FedRAMP) deployments require.
- Build resilient backend services in Python/FastAPI.
- Own schema design for multi-tenant data, tenant-aware query patterns, and operational correctness in a regulated environment.
- Build the services behind tenant provisioning, self-serve administration, and the customer onboarding lifecycle.
- Support billing, pricing, and metering surfaces for enterprise customers.
- Own and evolve Lila's public APIs (REST, streaming, async) designed for both human developers and autonomous agents as first-class consumers.
- Ship SDKs and define the tool/function interfaces agents call.
- Build the integration paths that connect MCPs, agents, and data into the platform — including how customers bring their own MCPs, agents, and data, and how those integrations are scoped, isolated, and trusted within a tenant.
Benefits
- competitive base compensation with bonus potential
- generous early-stage equity
- medical, dental, and vision coverage
- employer-paid life and disability insurance
- flexible time off with generous company wide holidays
- paid parental leave
- an educational assistance program
- commuter benefits, including bike share memberships for office based employees
- a company subsidized lunch program
