Job description

The Role

We are seeking a Junior Full Stack Software Engineer to join the team building the software behind Chemify’s robotic synthesis platform. You will work across the stack on real features — from backend services to the interfaces scientists use — with senior engineers close at hand to review your work and help you grow fast.

What sets this role apart is the platform itself: a rare early-career seat where the software you write helps physically make molecules, not just move data around.

If learning fast across the full stack on a real-world platform sounds like the right shape of job for you, we’d love to welcome you to our team.

Key Responsibilities
  • Build and ship full-stack features under the guidance of senior engineers.
  • Fix bugs, write tests, and improve tooling across backend services and web front-ends.
  • Learn how the platform turns experiment definitions into robotic execution, and contribute to it.
  • Take part in code reviews, design discussions — growing your ownership over time.
About You

You are early in your career but serious about the craft — curious, quick to learn, and energised by hard problems. You ask good questions, act on feedback, and want to grow alongside engineers who will push you.

We expect you to bring:

  • 0–2 years of software experience (internships, projects, or a strong portfolio count).
  • Working knowledge of at least one backend language ([Python/C/C++)]
  • Strong fundamentals and a genuine appetite to learn quickly.
  • Clear communication and comfort asking questions and acting on feedback.

Beneficial Skills

  • A degree in computer science, engineering, or a related field — or equivalent self-taught proof.
  • Any exposure to robotics, hardware, lab automation, or scientific computing.
Why Join Chemify?

Impact. Even early on, your work ships into a platform that physically makes molecules — you will see the results of what you build.

Autonomy. You will be trusted with real features from the start and given room to grow your ownership.

Ambition. We are a Series B deep-tech company at the frontier of AI, robotics, and chemistry — a place to learn fast, surrounded by people who will raise your bar.
