Software Engineer - Frontend

Can write legible, maintainable, and performant frontend code - ideally using TypeScript and React.

Are experienced with APIs and server-client communication like REST and GraphQL.

Have experience with running a live production software.

Are passionate about staying on top of current development best practices, libraries and frameworks.

Are comfortable working with unfamiliar backends, ideally with some exposure to languages like Rust.

Communicate well in English, both verbally and in writing.

Enjoy collaborating with others, including reviewing code and pair programming.

Are comfortable working asynchronously (writing PRs and RFCs, having discussions by email).

Strive to improve yourself, your peers, and the culture you work in over time.

Feel like ethical considerations are an inherent part of engineering.

Note: We operate at an intersection where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don’t meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.

Helsing’s work is important. You’ll be directly contributing to the protection of democratic countries while balancing both ethical and geopolitical concerns

The work is unique. We operate in a domain that has highly unusual technical requirements and constraints, and where robustness, safety, and ethical considerations are vital. You will face unique Engineering and AI challenges that make a meaningful impact in the world

Our work frequently takes us right up to the state of the art in technical innovation, be it reinforcement learning, distributed systems, generative AI, or deployment infrastructure. The defence industry is entering the most exciting phase of the technological development curve. Advances in our field of world are not incremental: Helsing is part of, and often leading, historic leaps forward

In our domain, success is a matter of order-of-magnitude improvements and novel capabilities. This means we take bets, aim high, and focus on big opportunities. Despite being a relatively young company, Helsing has already been selected for multiple significant government contracts

We actively encourage healthy, proactive, and diverse debate internally about what we do and how we choose to do it. Teams and individual engineers are trusted (and encouraged) to practise responsible autonomy and critical thinking, and to focus on outcomes, not conformity. At Helsing you will have a say in how we (and you!) work, the opportunity to engage on what does and doesn’t work, and to take ownership of aspects of our culture that you care deeply about

Significant recent experience with React.

Familiarity with backend interface tools like REST, GraphQL, gRPC/Protocol Buffers.

Established understanding of modern JS bundlers, such as Vite, and experience maintaining frontend infrastructure.

Experience with styling utility-class libraries such as TailwindCSS and building reusable React component libraries.

Data visualization expertise (e.g., D3.js, custom charting, or complex dashboard design).

Background in designing software for aerospace, defense, or AI end users.
