Senior Full-Stack Engineer - Team Agent

About the role

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. You'll work alongside experienced engineers, contribute to real product impact from day one, and grow your skills in a fast-moving, high-ownership environment.

Taktile is a hybrid company. This role requires working at least 3 days per week from our Berlin HQ, London Office or Iasi Hub.

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.
• Engage actively in team rituals such as daily syncs, planning sessions, demos, and technical deep-dive discussions.
• Grow as an individual and accelerate your career by learning from experienced team members, contributing to a foundational layer of the product, and joining cross-team learning groups.
• For career growth at Taktile, this role will involve daytime ops duty and at some point joining an on-call rotation, so you need to have passion for owning systems end to end and grow your DevSecOps skills as well.

Team's tech stack

• Backend: Python (FastAPI, Pydantic)
• Frontend: React, TypeScript
• Data: DynamoDB, Postgres
• Cloud: AWS serverless (Lambda, API Gateway)
• AI: LLM orchestration, tool-use frameworks, streaming execution

Requirements

• Strong engineering fundamentals with a passion for simplicity and precision.
• Fluency in English, both written and spoken, is essential as we operate in a remote environment requiring clear and effective communication. Strong English skills are also crucial to efficiently interacting with AI.
• 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 but not required

• 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).

OUR OFFER

• Work with colleagues that lift you up, challenge you, celebrate you and help you grow. We come from many different backgrounds, but what we have in common is the desire to operate at the very top of our fields. If you are similarly capable, caring, and driven, you'll find yourself at home here.
• Experience a truly flat hierarchy and communicate directly with founding team members. Having an opinion and voicing your ideas is not only welcome but encouraged, especially when they challenge the status quo.
• Learn from experienced mentors and achieve tremendous personal and professional growth. Get to know and leverage our network of leading tech investors and advisors around the globe.
• Receive a top-of-market equity and cash compensation package.
• Get access to a self-development budget you can use to e.g. attend conferences, buy books or take classes.
• Receive a new Apple MacBook Pro, as well as meaningful home office set-up.

OUR STANCE

• We're eager to meet talented and driven candidates regardless of whether they tick all the boxes. We're looking for someone who will add to our culture, not just fit within it. We strongly encourage individuals from groups traditionally underestimated and underrepresented in tech to …
