About Throne

Throne is a continuous tracking device for getting personalized insight about gut health and hydration. Co-founded by John Capodilupo — co-founder and former CTO of WHOOP — we're bringing the rigor of continuous health tracking to two signals that have long been a guessing game. Our north star is to improve health and save lives.

Backend Platform & Indexing

We’re looking for a Senior Backend Engineer to own major backend and infrastructure problems end-to-end across product APIs, async systems, media/ML indexing pipelines, and cloud infrastructure.

This is a hands-on, technical ownership role. You will frequently be given an objective rather than a detailed specification and will be expected to understand the problem, determine the right architecture and implementation plan, identify risks and dependencies, execute the work, and operate the resulting system in production.

You should be comfortable being the person who turns “we need this system to handle 50× the workload” into a concrete technical plan and then makes it happen.

Location

Austin, Texas (In-person)

What You’ll Own

• End-to-end technical ownership means translating company and product needs into technical requirements, architecture, implementation plans, and production systems without requiring a pre-defined engineering specification.
• Backend architecture across our Go services, including gRPC, grpc-gateway, REST, internal APIs, and shared libraries.
• The indexing and processing pipeline for large media/session workloads: object storage ingest, queueing, worker orchestration, ML inference integration, session indexing, and downstream metric generation.
• Cloud infrastructure and deployments, primarily in Terraform across AWS ECS/Fargate, networking, storage, queues, IAM, secrets, databases, and ML endpoints.
• Performance, reliability, and cost optimization across APIs, worker fleets, databases, queues, storage, and model-serving integrations.
• Database and data-flow design, including schema changes, migrations, concurrency patterns, throughput tuning, and operational safeguards.
• Observability and operational excellence: tracing, metrics, alerting, incident response, runbooks, capacity planning, and failure analysis.
• Engineering process improvements for the backend: design reviews, code reviews, testing strategy, rollout safety, and technical standards.

What We’re Looking For

• 7+ years of backend/infrastructure engineering experience, including substantial ownership of production systems and at least several examples of leading complex technical work from ambiguous problem statement through deployment and operation.
• Deep Go experience building and operating distributed backend systems.
