SUMMARY

We are looking for a Senior Software Engineer with deep Python expertise to join our Engineering team. You’ll be a core builder on Hello Rasa — our interactive developer playground that lets engineers prototype AI agents powered by CALM (Conversational AI with Language Models) in minutes, without any setup. Think templates, a built-in copilot, a real-time inspector, and full code access — all in the browser.

This is not a maintenance role. You’ll shape the product experience from the ground up: driving architecture decisions, owning features end-to-end, and working closely with Engineers, Product Managers, and Designers. You’ll report to an Engineering Manager. We build in Python, with additional tooling across Node and React.

Full-time - 100% remote - Location: Serbia

• This is a remote position, but we cannot hire anybody outside of Serbia for this position.

• Rasa can not assist with work authorization (visa sponsorship) for this position.

ABOUT THIS ROLE

As a Senior Software Engineer on the Hello Rasa team, you won’t just write code — you’ll shape how it gets built. You’ll lead architecture decisions, push on quality, and take full ownership of complex, user-facing features. Concretely, you’ll:

• Lead architecture and technical design for major features in Hello Rasa — the developer playground that gives engineers a fast, code-first path into building production-grade AI agents with CALM

• Drive product discovery alongside PMs and Designers — proactively identifying problems and shaping solutions before they’re handed to you

• Make decisions under ambiguity: break down complex, uncertain projects into clear milestones and move the team forward without waiting for perfect requirements

• Set the standard for code quality through rigorous code reviews, sharp documentation, and a sustained commitment to engineering excellence

• Navigate and improve our tech stack: Python 3, Fly.io, Redis, RabbitMQ, Postgres, GitHub Actions, AWS, Kubernetes, and related frameworks

• Balance pragmatism and correctness: solve user problems without over-engineering; know when to optimize and when to ship

ABOUT YOU

• 5+ years of professional Python experience, with a strong track record of designing and shipping production-grade systems

• Deep experience building complex, scalable, and highly reliable distributed systems

• Demonstrated ability to own technical decisions — not just implement them

• Strong product instinct: you think in terms of user outcomes and developer experience, not just technical correctness

• Comfortable operating in a fast-moving, product-led organization where requirements evolve

• Proven track record of mentoring engineers and raising the technical bar of a team

• Excellent communicator — you can align stakeholders, write crisp technical specs, and translate complexity for non-engineers

• Based in Serbia, collaborating with teammates across Serbia, Germany, and the UK

Please keep in mind that we are describing the background we imagine would best fit the role. Even if you don’t meet all the requirements, yet you are confident that you are up for the task, we absolutely want to get to know you!

MEET YOUR TEAM

You’ll be joining Team Swift - a cross-functional squad of 8 people building Hello Rasa, Rasa’s interactive developer playground. The team spans Serbia and Germany, and includes 4 full-stack engineers, 1 ML engineer, 1 Staff QA, 1 PM, and 1 Staff Designer.

Team Swift sits within Rasa’s broader Engineering organization and works in a product-led, iterative way - close collaboration between engineers, design, and product is core to how the team operates. You’ll be working on a product that is the entry point for developers into the Rasa ecosystem, with direct impact on how engineers first experience conversational AI with CALM. We aim to release at least once per week, and we’re constantly polishing our processes to be faster and more efficient.

• Flexible hours and a dedicated remote budget

• A stipend for professional development & 6 paid education days to help you grow within your role

• 26 days of PTO + paid sick leave + paid public holidays
