Senior Rust Engineer - Audio Technology

Please note: Candidates must already be based in and authorized to work in the United States, no exceptions.

A small, profitable audio technology company is hiring a Senior Rust Engineer to take full ownership of the real time decisioning system at the core of their product. It makes billions of decisions a month and reaches a very large consumer audience through well known media and consumer technology partners.

Production Rust on AWS serverless. A dense set of interacting constraints, real time guarantees, and a service that cannot be taken offline while you work on it. Not greenfield: the codebase is mid migration, and you would step in, hold its architectural context and move it forward without breaking what already works.

What they are looking for

• 5+ years production backend, with Rust at production depth
• Real fluency in distributed failure modes: retries, dead letter queues, idempotency, at least once delivery
• AWS serverless: Lambda, DynamoDB, SNS/SQS
• Experience taking over a live codebase mid lifecycle
• Daily, practical use of coding agents
• Pragmatic. Builds on what exists rather than arriving and rewriting it.

Why it is worth a look

• Complete ownership of a core system, not a slice of one
• Real consumer scale and a genuinely hard problem
