This role reports to senior engineering leadership and owns applied AI architecture, model evaluation strategy, and end-to-end delivery of production AI capabilities.

- Own AI systems from prototype through production, including deployment, observability, latency optimization, and reliability
- Define evaluation frameworks to measure model quality, reduce hallucinations, and improve system performance over time
- Make architectural decisions across prompting, retrieval strategies, model selection, and fine-tuning where appropriate
- Contribute across backend and frontend systems to deliver complete AI-powered product experiences
- Partner closely with product and design to shape technical feasibility and product direction
What You Bring
- 6+ years of software engineering experience, including hands-on work building AI or LLM-powered systems
- Strong experience with retrieval-augmented generation, tool use, and agent orchestration patterns
- Deep system design judgment across scalability, reliability, and production tradeoffs
- Experience evaluating model performance and implementing safeguards for real-world usage
- Solid full-stack engineering fundamentals across modern backend and frontend environments
- Ability to communicate complex technical decisions clearly across engineering and product stakeholders
Bonus Experience

- Familiarity with LangChain, LlamaIndex, or custom orchestration frameworks
- Exposure to AI safety, guardrails, and responsible deployment practices
- Background in SaaS, analytics, or customer-facing data platforms
Who This Is For
- Builders who want to define new systems rather than maintain existing ones
- Engineers with strong product instincts who care about what should be built, not just how
- Hands-on technical operators comfortable moving between architecture, experimentation, and production delivery
- Candidates energized by high-autonomy environments with strong in-office collaboration
