Senior Platform Engineer (Hybrid - SF)
role at
Seam .
Why Seam? We build IoT infrastructure that powers smart devices globally. If you've used a code to enter an Airbnb, you've probably used Seam. Our customers range from startups to public companies. Platform engineering here is a force multiplier—you'll directly impact every customer and every line of code we ship. Our team includes alums from Nest, Apple, Stanford, YC. Backed by Tiger Global, Root VC, and founders from Stripe, Plaid, Airbnb.
About The Role We're looking for a Senior Platform Engineer to join our 3‑person platform squad. You'll own the systems that make our engineering team productive and our APIs reliable. Your focus: build efficient TypeScript tooling that lets engineers ship device integrations in days instead of weeks, create fast testing infrastructure, scale our background workers, and improve observability across our platform. We're growing rapidly into enterprise and need rock‑solid infrastructure without sacrificing developer velocity. We value pragmatism over perfection. Ship fast, learn quickly, iterate. You should be comfortable diving deep into TypeScript, optimizing PostgreSQL queries, and teaching the team what you learn.
What you’ll work on
Platform Infrastructure
– Design systems handling millions of API requests and complex background jobs for device communications
Developer Experience
– Build TypeScript tooling and frameworks that accelerate integration development, improve code sharing, create abstractions that let engineers ship faster
Performance & Scale
– Optimize PostgreSQL queries, design caching strategies, ensure our platform handles 10x growth
Testing & Reliability
– Transform testing from bottleneck to competitive advantage
About You We look for people with
sharp minds with kind souls .

Collaborative – work closely with product engineers
Clear communicator – explain complex systems simply
Qualifications
5+ years backend engineering with platform/infrastructure focus
Expert TypeScript and PostgreSQL (query optimization, scaling)
