Member of Technical Staff, Agent Infrastructure
San Jose$170k - $400kfull-timePosted 7mo ago
About the role
Role focused on building the platform and runtime that powers Hark's AI agent, including orchestration, tool execution, memory and streaming infrastructure, and cross-stack primitives to enable production-ready intelligent systems.
Responsibilities
- Build the core runtime that powers Hark's agent platform. Orchestration, tool execution, memory retrieval, streaming, and the systems that make all of it work reliably together.
- Own features end-to-end, from early prototyping alongside model researchers to production deployment and iteration based on real usage.
- Architect the platform primitives that the rest of the product team builds on. Agent runtimes, execution sandboxes, memory APIs, streaming pipelines.
- Instrument and evaluate the product. Write evals, track quality regressions, and feed signals back into the model and product loop.
- Work across the stack when the problem requires it.
Qualifications
- Strong systems engineering fundamentals. You are comfortable designing APIs, building reliable infrastructure, and reasoning about performance, concurrency, and failure modes.
- Experience building production systems that real users depend on. You know the difference between something that works in a demo and something that works at scale.
- Genuine curiosity about AI and agents. You have built with LLMs, thought about how they fail, and have opinions about what makes agentic systems reliable.
- Comfort with ambiguity and fast iteration. You can start with a rough problem, build something real, learn from it, and improve quickly.
- Strong communication. You can explain tradeoffs clearly, collaborate across teams, and make good decisions with incomplete information.
- 5+ years of relevant software engineering experience. Experience at a fast-growing AI or infrastructure-focused company is a strong plus.
- Bonus: hands-on experience with agent frameworks, streaming architectures, execution sandboxes, memory systems, or tool integration protocols.
