Senior Full-Stack Engineer - Team Agent

Taktile is building a platform for creating, publishing, and executing AI-powered agents that help teams automate complex workflows in financial services. The Agents team owns the agent execution runtime, tool orchestration, and platform infrastructure that makes this possible, including the conversational copilot experiences built on top of it across the product. We are hiring a Full-Stack Engineer to help build and ship production features across this entire stack, from the agent runtime and tool orchestration layer in the backend, to the conversational copilot experiences users interact with every day.

What you'll do

• Build and ship features end-to-end for Taktile's AI agent platform: backend in Python (FastAPI) on AWS serverless infrastructure, and frontend in React and TypeScript.
• Build conversational copilot experiences end to end: chat UI components, streaming responses, rich in-chat interactions, and human-in-the-loop approvals.
• Improve how agents run, how they connect to external tools, and how they behave when something goes wrong.
• Own your work end-to-end: collaborate on scope, implement, test, release, and iterate based on real usage and customer feedback.
• Use leading-edge AI tools (e.g. Claude) on a daily basis to move faster, improve quality, and build AI-native capabilities where it makes sense.
• Review pull requests with depth, improve test coverage and CI/CD, and raise the bar on reliability and engineering excellence.
• For career growth at Taktile, this role will involve daytime ops duty and at some point joining an on-call rotation.

What you'll need

• Strong engineering fundamentals with a passion for simplicity and precision.
• Fluency in English, both written and spoken, is essential as we operate in a hybrid environment requiring clear and effective communication.
• Prior industry experience building full-stack web applications (this is not an entry-level position).
• Proficiency with React and TypeScript, and experience building rich, interactive user interfaces.
• Experience with Python back-end development, building and operating RESTful APIs, and working with databases.
• Experience integrating into AWS or similar cloud providers.

Nice to have

• Experience building chat or conversational UIs, real-time/streaming interfaces, or data visualization.
• FastAPI and Pydantic experience.
• DynamoDB or Postgres, SQLAlchemy.
• Exposure to LLM application development, agent frameworks, MCP, or building developer tools.
• Prior ops or on-call experience.
• Experience with distributed systems, async task processing, or observability tooling (tracing, metrics, logging).

What they offer

• Top-of-market equity and cash compensation package.
• Self-development budget for conferences, books, or classes.
• New Apple MacBook Pro and meaningful home office set-up.
• Flat hierarchy with direct communication to founding team members.
• Learning from experienced mentors and access to network of leading tech investors and advisors.
