Senior AI Software Engineer

Amplitude • San Francisco, CA

12h • Hybrid

About The Position

Amplitude's People Systems & AI team is on a mission to rebuild how HR teams interact with technology—moving from manual, system-centric workflows to AI-native, outcome-driven experiences. We are building a modern HR stack powered by multi-agent orchestration, custom applications, and intelligent automation layered on top of our core systems (Workday, Greenhouse, Anaplan, NetSuite, and more). As our Senior AI Software Engineer, you'll be the primary technical builder on the team, owning the design, development, and production lifecycle of custom AI-powered applications that connect and orchestrate data across our people systems.

Requirements

• 5+ years of software engineering experience with strong fundamentals across frontend and backend development, including proficiency in Python and/or Node.js
• Hands-on experience building and consuming REST APIs and event-driven integrations
• Experience deploying and managing applications on AWS (Lambda, S3, API Gateway, RDS, or similar)
• Strong understanding of security best practices for applications handling sensitive or personal data
• Experience with AI/ML APIs and LLM integrations (OpenAI, Anthropic, or similar)—building agents, RAG pipelines, or AI-powered workflows
• Ability to work autonomously, move fast, and make sound architectural decisions without heavy oversight

Nice To Haves

• Familiarity with HR or people systems (Workday, Anaplan, ATS like Greenhouse, Ashby or similar)—you don't need to be an admin, but understanding the data model matters
• Experience with iPaaS or integration platforms like Workato, MuleSoft, or Zapier, and a sense for when to use them vs. writing custom code
• Hands-on experience with low-code/pro-code app builders like Superblocks or Lovable for shipping internal tools quickly
• Experience with multi-agent orchestration frameworks (LangChain, LangGraph, CrewAI, or similar) and agentic AI patterns like tool use, memory, planning, and chaining
• Comfort operating in fast-moving environments where the roadmap evolves and priorities shift as new capabilities emerge

Responsibilities

• Build custom AI-powered applications and multi-agent pipelines that orchestrate data and workflows across people, finance, and enterprise systems—think automated recruiting assistants, performance review agents, and workforce planning triggers
• Own end-to-end development of secure, production-grade internal tools, including architecture, AWS cloud infrastructure, security, deployment, and maintenance
• Design and build API integrations that make data flow reliably and safely between HR platforms, with security-first design for sensitive employee data
• Partner closely with HRBPs, recruiters, finance, and People leadership to translate business requirements into working software that non-technical users can actually use and trust
• Drive technical evaluation of new AI tools and frameworks, contributing to our two-track roadmap of committed outcome-based projects and short-cycle experiments on emerging capabilities

Benefits

• Excellent Medical, Dental and Vision insurance coverages, with 100% employer-paid premiums for employee Medical, Dental, Vision on select plans
• Flexible time off, paid holidays, and more
• Generous stipends to spend on what matters most to you, whether that’s wellness (monthly), commuter transit/parking (monthly), learning and development (quarterly), home office equipment (annual), and much more
• Excellent Parental benefits including: 12-20 weeks of Paid Parental Leave, Carrot Fertility Benefits/Adoption/Surrogacy support, Back-up Child Care support
• Mental health and wellness benefits including no cost employee access to Modern Health coaching & therapy Sessions and high quality physician office experience via One Medical membership (select U.S. locations only)
• Employee Stock Purchase Program (ESPP)
• Unlimited PTO
• 10 to 13 holidays annually (will vary)
• company sponsored 401(k) retirement plan
