Role details
Responsibilities
- Collaborate within a cross-functional team spanning engineering, machine learning, and product to quickly design, build, and launch new features across the stack.
- Work comfortably across all parts of our stack, which includes core backend (Kotlin), ML scripts for evaluation, data processing, and inference (Python), low-level media streaming (Rust), the app (Dart/Flutter), and internal tooling (Next.js/TypeScript).
- Elevate user experience by continually refining the reliability, performance, and scalability of the systems behind Ash.
- Rapidly investigate, diagnose, and resolve production issues with a focus on latency, reliability, and cost.

Requirements
- 6+ years of software engineering experience with a track record of operating production systems at meaningful scale in high-growth, high-quality environments.
- Strong systems instincts and real opinions about latency, reliability, and cost; you know what breaks first under load and you design around it.
- Driven by creating a world-class product with a world-class team, want to own what you build, and you're happy redesigning systems as production teaches you something new.
- Comfortable building across the full stack; a keen learner who picks up new languages, technology stacks, and concepts quickly.
- Experience working in a fast paced environment, taking systems from prototype to scaled production in weeks.
