About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Take ownership of a backend platform that handles high-volume processing workloads, with a focus on speed, dependability and cost control. Collaborate with machine learning colleagues to get models running in production, and share on-call duties within a small platform group.

What you'll do

- Own and improve the backbone platform that executes customer workloads, keeping it quick, dependable and economical as demand grows.

- Collaborate with machine learning engineers on hosting proprietary models efficiently and fitting them into live data pipelines.

- Build and maintain core infrastructure, including data stores, job coordination, resource allocation and cloud releases.

- Resolve performance, resilience and capacity problems across multi-service systems as traffic increases.

- Join the on-call rotation and take responsibility for the overall health of the platform.

Requirements

What we're looking for

- 5+ years of experience owning and scaling core infrastructure at a fast-paced startup or a respected, high-velocity technology company.

- If coming from a larger company, a Staff or Principal title or a clear record of fast promotion.

- Full-stack skills; this is not a pure infrastructure or DevOps position.

- Solid background building reliable, large-scale backend systems that coordinate work across many services.

- Strong Python skills, or deep experience in another systems language along with willingness to move to Python.

- Comfort taking part in on-call duties.

Bonus points

- Experience with cloud infrastructure and tuning how models are served.

- Experience at an early-stage startup.

- A degree from a top computer science program.
