Job Description

Amplitude is the leading digital analytics platform. We’re a team of startup engineers working on a new product within Amplitude. We’re building an AI-powered personal chaperone for users, embedded into websites and apps. It’s a chatbot, but it’s a lot better in a few ways: It uses AI to personalize responses to every user, leveraging the power of Amplitude data; It can show users around with a cursor – think “tour guide” mode; It can perform actions on behalf of users by using APIs and interacting with other agent. We’re looking for an excellent product builder to join us - someone who’s as excited as we are to build the next generation of UX and bring it to millions of users.

Job Responsibility

  • Owning the product: Our team is hyper-focused on building a great product - this includes using the product, listening to customer feedback, and surfacing ideas for where we can improve. There’s no engineering vs. product fences here - everyone is a product owner
  • Shipping features: Own full-stack features end-to-end: from ideation to design to implementation
  • Exploring the frontier: AI is constantly evolving - you’ll be testing out new models, techniques and libraries to chart the path forward

Requirements

  • Experience building full-stack features and applications
  • Experience with relevant technologies (We use Python on the backend and React for the frontend)
  • Strong product intuition - proactively identify improvements without being asked
  • Comfort with moving fast and making smart tradeoffs
  • Stellar ownership of features and code quality
  • Familiarity with LLMs/AI - either from work or your own exploration

Nice to have

  • You’ve been part of a small startup or skunkworks team and thrived in uncertainty
  • You’ve built agents using frameworks like Pydantic AI
  • You’ve worked deeply with TypeScript
  • You’ve worked with applications built on Temporal
  • You’ve built RAG pipelines before

What we offer

  • 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)

  • 7+ years of professional software engineering experience, with a proven track record of shipping scalable production systems
  • Deep hands-on experience with LLMs in real products — including prompt design, context management, evaluation, and understanding real-world limitations (hallucinations, latency, cost, reliability)
  • Experience building agentic systems is highly valued. Alternatively, deep hands-on work with advanced LLM workflows (tool use, multi-step reasoning, memory, orchestration) and a clear understanding of their trade-offs — along with the drive and technical maturity to quickly evolve toward agentic architectures
  • You think like a builder — ideally a former founding engineer or founder — with a strong instinct for shipping what truly moves the product and the company forward
  • You’re drawn to agent-native architecture and believe this is where software is heading. You’re excited to rethink codebases, APIs, and documentation so AI agents can reliably operate and scale
  • You rely on AI tools daily (e.g., Cursor, Claude Code) and treat them as a core part of your engineering workflow — constantly experimenting, refining prompts, and pushing them to meaningfully increase your speed and output
  • Comfortable working in distributed systems and event-driven architectures (e.g., queues, async processing, service-to-service communication)
  • Able to lead complex technical initiatives end-to-end, raising the bar for architecture, quality, and engineering culture
  • Candidates must have the legal right to work in the EU
