Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards.
As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously.
We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.
Helsing's maritime team is developing next-generation uncrewed underwater vehicles (UUVs), including the SG-1 Fathom platform and the Lura AI system, purpose-built to secure the subsea domain for open societies. As Supporting Tech Lead, you will sit at the centre of that effort, providing the whole-system engineering perspective needed to move the programme from prototype to a documented, repeatable, production-ready platform across a 40-unit build.
You will work alongside a skilled team of mechanical, electrical, and embedded engineers, bringing subsystems together into a coherent, buildable whole. Where competing design approaches create decision deadlocks, you will draw on your knowledge of what works underwater, what has been proven at depth, and what scales to production, to make well-reasoned calls and keep the programme moving. You will also play an active part in day-to-day team coordination, ensuring that deep domain expertise converts into concrete decisions and forward momentum rather than further analysis. The work is technically demanding, the timelines are short, and the output has direct relevance to the security of open societies.
Own the Production Pathway:
Ensure every design decision accounts for manufacturing, assembly, and test from the outset, so that unit 37 can be built identically to unit 1
Own design documentation, version control, and assembly instructions to a standard complete enough for someone outside the room to build from
Support supplier selection and qualification, identifying volume-available components, custom-development requirements, and single-source risks that could affect programme delivery
Drive the transition from engineer-built prototype to a fully documented, production-ready build across the 40-unit programme
Drive Integration & Testing:
Lead the integration of all subsystems, including the flight-controller board, edge compute, hydrophone array, satcom, network router, and sensor suite, ensuring each interface is clearly defined and validated
Coordinate with the Software Tech Lead to ensure the on-glider software stack and hardware requirements remain mutually consistent throughout the development cycle
Define and execute the test strategy from bench through tank trials to open-water sea trials, capturing findings and iterating the design accordingly
Break Design Deadlocks:
Apply whole-system UUV knowledge to resolve competing design approaches, drawing on what has been validated at depth and what is known to scale to production
Assess available options with the information at hand, make well-reasoned calls, communicate the rationale clearly to the team, and keep the programme moving
Ensure the team's collective expertise in mechanical, electrical, and embedded domains converts into forward momentum
Close the Design:
Work with the existing technical team to advance Helsing's maritime products from current concept to a fully buildable, producible system
Own trade-off decisions that span mechanical, electrical, and embedded software boundaries, articulating reasoning with enough clarity to secure team alignment
Distinguish between designs that are ready to build and those that need further iteration, preventing the programme from stalling in unnecessary refinement cycles
Embed scaled-manufacturing thinking from the outset, not as a downstream consideration
Have built, integrated, tested, and deployed complex electromechanical systems in real operational environments, not in simulation or on paper
Make systems-level engineering decisions that span mechanical, electrical, and embedded software boundaries with clarity and confidence
Resolve technical trade-offs under ambiguity, document your reasoning transparently, and bring a multi-disciplinary team to a shared decision
Have led design reviews and coordinated technical output across engineering teams with different domain specialisms
Know when a design is ready to build and when it requires further iteration, and have the judgement to act on that distinction
Note: We operate in an industry 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.
Direct experience with UUVs, AUVs, or underwater gliders, including buoyancy-driven platforms, variable buoyancy systems, or underwater propulsion
Familiarity with subsea communications (Iridium SBD), underwater acoustics, or edge compute platforms such as Jetson
Experience delivering within a defence or defence-adjacent programme, including LARS and vessel operations
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
Competitive salary and VSOP options
Relocation support: up to €2,500 and 4 weeks temporary accommodation
Learning: €500/£450 yearly allowance
Health & wellness: gym membership and mental health support (Nilo.health)
Social: regular company events and monthly social allowances
Enhanced parental leave: 22 weeks fully paid for primary caregivers & 6 weeks for secondary caregivers
Family support: 5 days of paid family emergency leave, 100% remote work option during pregnancy and phased return to work
A hands-on onboarding program (affectionately labelled “Infraduction”), in which you will be building tooling and applications to be used across the company. This is your opportunity to learn our tech stack, explore the company, and learn how we get things done - all whilst working with other engineering teams from day one
Helsing is an equal opportunities employer. We are committed to equal employment opportunity regardless of race, religion, sexual orientation, age, marital status, disability or gender identity. Please do not submit personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, data concerning your health, or data concerning your sexual orientation.

Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards.
As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously.
We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.
At Helsing we develop and deliver AI-based capabilities and the enabling infrastructure that allow semi-autonomous platforms to localise, navigate, and perceive the world in real time. We build software that is subject to significant and unorthodox technical constraints, must operate in a wide variety of constantly-changing environments, and has to support an ever-growing list of challenging use-cases. What we build ultimately ends up in the hands of real people in high-risk, high-stress situations, so must be both reliable and frictionless. Taken together, this brings a whole host of interesting engineering challenges across a wide variety of fields that you’ll help us solve. To give some examples:
Distributed systems (e.g., intermittent connectivity and byzantine actors)
Embedded computing (e.g., resource-constrained compute and reverse-engineering)
Robotics (e.g., control systems and tasking)
Networking (e.g., long-range low-bandwidth radios and cross-medium routing)
Deployment infrastructure (e.g., air-gapped devices and heterogenous fleets)
Security (e.g., data sharing in low-trust, no-TLS networks and actually-secret data handling)
Machine learning (e.g., systems for model development, storage, and dissemination)
In several of these areas, we are working near the state-of-the-art; we actively read (and sometimes implement) research papers, and often need to push even further to make theory work in practice. In others, we are applying well-known techniques to real-world situations (with real-world limitations) that have never been used in before, which requires skill, diligence, and honing a deep understanding of the underlying technologies.
Review code contributions, proposals, and RFCs from colleagues. At Helsing we strongly believe that unblocking others takes precedence over spending more time on your own work.
Propose and implement new features, capabilities, algorithms, infrastructure, or even full products across our stack. We encourage our engineers to look beyond their immediate team for missed opportunities, and to speak up when they identify one.
Become a mentor, find a mentee, and help support and develop our interviewing pipeline. The people make or break the company, and we want as many engineers as possible to be part of fostering and growing the organisation.
Share your experience and technical know-how with other Helsingers. We host tech talks, get together for smaller “let’s learn together” groups, run topical office hours (e.g., on Rust), etc. to help each other get better with time.
Maintain our existing software stack, including working with internal and external customers to identify issues, improving operational reliability and performance, and fending off technical debt. The stack is a mix of Rust and Python, with Python mainly living in the ML-heavy sections.
Further develop our tests and benchmarks, both at the micro and macro level. We operate in a domain where robustness is of the utmost importance, and an extensive and ever-improving test suite is key to achieving that. And without thorough benchmarks, we would be flying blind.
Present your work at our weekly demo sessions. We want engineers to come together around what they are working on and to feel like they are not endlessly squirrelling away at something that doesn’t matter. To that end, we host (and actively work towards) demo sessions that allow early feedback, celebration of progress, and a better shared understanding of everything that goes on at Helsing.
Can write legible, maintainable, and performant code.
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).
Have backend development experience, ideally with a language like Rust, Java, Go, or C++.
Are familiar with backend interface tools like REST, GraphQL, gRPC/Protocol Buffers, and Arrow.
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.
Rust and Python specifically.
Container-based and cloud-native application architectures (e.g., Docker, Azure, AWS).
Metrics tooling (e.g., Prometheus, Grafana, ELK).
SQL and streaming database systems.
Routing protocols (e.g., IGP, BGP).
Cryptographic protocols (e.g., Signal, WireGuard).
Hardware interfaces (e.g., Arduino).
Robotics (e.g., control systems).
Production ML systems.
