Senior Software Engineer, Apps & APIs

What you might do in your first 6 months:

• Help take our MCP server from early-stage to production-grade: design decisions, implementation, and all the rough edges in between
• Contribute to our public APIs: clarity, consistency, and best practices matter more than ever as our users are increasingly building AI-powered workflows
• Build backends for agentic apps: the patterns for this greenfield work are still being defined and you'll have a strong voice in how we build
• Work closely with the EM and your teammates to shape how this team builds: you’ll have real opportunity to help define what good looks like here, not just execute against it

Things you have experience in:

• Strong Python engineer: you write idiomatic Python, design and ship production APIs in it, and it's your natural default
• Comfortable enough in Ruby (Rails) to navigate the codebase, give useful PR reviews, and contribute without needing to be carried
• Designing and shipping APIs with real external consumers: developer experience, versioning, and reliability are priorities for you
• Shipping in an environment where 'good enough to learn from' is a real engineering value, not a compromise
• Hands-on experience with MCP and agentic AI patterns: you've built real tools, integrations, or apps in this space

Things that should excite you that might scare off other folks:

• Building with emerging tech like MCP and agentic AI: you’re willing to make opinionated architectural bets in a landscape that is continually evolving
• Working on customer-facing products with technical users: your users are developers, marketing analysts and data scientists who will notice when something isn’t right
• Startup pace is real: things move fast, not everything is written down, and priorities shift - you know how to make progress anyway
• Being part of a remote, async-first team spread across time zones where clear written communication is essential

What you'll work with:

• Python & Ruby on Rails
• REST APIs & MCP
• AWS Cloud Services & Heroku
• Bedrock AgentCore, Anthropic SDK, LangChain/LangGraph
• PostgreSQL & Redis
• Docker, Terraform, Kubernetes, GitHub Actions
