• Proven experience shipping LLM-powered features to production (non-negotiable)
• Deep expertise in:

• RAG systems (advanced retrieval evaluation)
• LLM evaluation methodologies (golden sets regression testing)
• Prompt engineering at API level
• Agent architectures (ReAct tool calling planning loops)
• Strong understanding of trade-offs (cost latency scalability)
• Ability to work independently in ambiguous fast-moving environments

Nice-to-Have:

• Fine-tuning experience (LoRA SFT DPO)
• Inference stack experience (vLLM TGI )
• Observability tooling (Langfuse LangSmith)
• Prior experience in early-stage or high-ownership teams

• Public work (GitHub blogs talks) demonstrating depth

• Advanced Python and backend engineering
• LLM systems (RAG agents prompting evaluation)
• API design and system architecture
• Docker Git CI/CD
• Understanding of inference systems and scaling

Soft Skills:

• High ownership and accountability
• Ability to operate in ambiguity (build while flying)
• Strong decision-making and trade-off analysis
• Clear communication with cross-functional teams

What Success Looks Like in the First 90 Days:

By the end of Month 1:

• Deeply understand Crosstalk/Zync architecture and ongoing projects
• Contribute meaningfully to ongoing systems (not just onboarding tasks)
• Identify gaps or risks in current implementations

By the end of Month 2:

• Own and deliver a critical feature or system component end-to-end
• Improve an existing system (performance evals or architecture)
• Demonstrate strong independent execution

By the end of Month 3:

• Act as a trusted senior engineer on the team
