Senior Software Engineer - AI Agents

Summary Hatch engineering culture is driven by speed, ownership, and impact. We're a small, ambitious team building AI that transforms how service businesses grow, and we move fast. Engineers own problems end to end, ship to production early, and work across a modern stack (Elixir, Python, Go, React + TypeScript) on problems that directly shape the customer experience. At the end of the day, we're here to build something that matters, grow as engineers, and do it together. As part of the AI agents team, you'll work at the intersection of classic product engineering and AI - building the underlying systems that let our AI agents reason, act, and improve. Your work has a direct, measurable line to customer revenue. This opportunity requires you to be located in the United States. We’d love to have you apply, even if you don’t feel you meet every single requirement in this posting. At Hatch, we’re looking for great people, not just those who simply check off all the boxes. What you'll do - Design, build, and maintain scalable backend services, APIs, and third-party integrations and clearly communicate technical decisions and trade-offs to the team. - Partner closely with product and design as a true thought partner - bring a strong product sense and a product-oriented mindset to every feature, balancing user needs, business goals, and technical trade-offs. - Own your work end-to-end and deliver results on time, partnering across team boundaries when needed to unblock yourself, drive clarity, and ship. - Apply industry-standard engineering practices: thorough code review, automated testing, CI/CD, progressive delivery with feature flags and A/B experimentation, observability, and clear technical documentation. - Set the technical direction and quality bar for the team across architecture, code quality, and delivery practices. - Proactively identify and resolve critical technical issues, contribute to architectural discussions, and raise the bar for the group. - Mentor and guide junior engineers, fostering a culture of learning and technical excellence. What it takes to succeed - Solid backend experience in one or more of Elixir, Go, Python, or a comparable server-side language, with the curiosity and adaptability to pick up new languages and frameworks as our stack evolves. - Deep understanding of backend systems, API design, and data modeling - comfortable owning features end-to-end from architecture to production - Familiarity with ML/LLM systems including prompt engineering, evals, and model behavior is a plus. - Sense of ownership and bias for action - you take ambiguous problems from start to finish, work across team boundaries to unblock yourself when needed, and stay accountable through delivery. - Excellent communication skills and the ability to collaborate effectively with technical and non-technical stakeholders. - Eager to keep up with the ever-changing landscape of AI capabilities - actively exploring new models, tools, and techniques, and thoughtfully applying them to your work and to the product. - Several years of experience shipping production software, with a track record of leading projects from spec to launch alongside multiple contributors. What you'll get - Full responsibility for projects from day one, a collaborative team, and a dynamic work environment. - This opportunity has the option to be fully remote in all locations across the US - Effective your first day: Full medical, vision, and dental - Mental health support and services via Modern Health - 15 days PTO (accrual begins on date of hire and increases with 2+ years of tenure thereafter), 12 paid holidays, plus one floating holiday - Up to 14 weeks of parental leave - Monthly wellness stipend - 401(k) retirement savings plan - Employee stock purchase plan - Professional development reimbursement - Work from home reimbursement Why Hatch - Shape the future of AI-driven customer service - Build alongside founders and leaders who value speed, ownership,a
