Welcome to Davidhorn 

Davidhorn is empowering investigators with tools to make interviews efficient, accurate and fair. With over 40 years of experience as Europe’s leading provider of evidential interview solutions, Davidhorn is committed to enhancing justice and peace to strengthening institutions, promoting peaceful societies and providing access to justice for all. 

Our commitment to advancing global justice through technology aligns with UN’s Sustainable Development Goal 16.3 and reflects our dedication to a fair, peaceful world where trust in the justice system is universal. 

With offices in Oslo, Grimstad and Luton we have a great team of technical people, commercial people, and leaders. We are continuing our growth and hope that you would like to join our team as Lead Engineer in either Grimstad or Oslo. 

Lead Engineer, Investigative Intelligence

At Davidhorn, we build technology that helps investigators work faster, think more clearly, and reach fair outcomes- under pressure. Our tools are used in over 40 countries by professionals who protect the vulnerable and uphold justice. Now, we're building a new product line that combines AI, research-based practice, and public-sector reality to support the next generation of investigations.

We’re now looking for a Lead Engineer to help bring this vision to life. Some of your key responsibilities will include:

• Product & Architecture Focus

• Help shape the technical foundation of Investigative Intelligence- an AI-powered product that supports structured and ethical police investigations.
• Define a clear and forward-looking technological direction, ensuring the architecture is scalable, maintainable, and aligned with product needs.
• Select appropriate tools, frameworks, and architectural patterns to support performance, privacy, and scalability.
• Lead the development of the product and work closely with other engineers and domain experts.

• Cross-functional & Ethical Development
• Collaborate with investigators, researchers, and stakeholders to understand real-world challenges and translate them into higly valuable effective, responsible technical solutions.
• Ensure compliance with relevant legal and ethical standards (GDPR, youth protection, consent), especially in the use of machine learning and AI.
• Work with privacy and legal advisors to develop transparent, auditable, and explainable AI components that meet the highest standards of accountability.

Who we are looking for

We’re looking for a curious and passionate Lead Engineer who wants to turn advanced AI models into real, usable products. You combine technical insight with humility, and you thrive in a dynamic and collaborative setting.

You’re passionate about building ethical technology, have an open mindset, and enjoy learning -and teaching- as part of a team. An interest in psychology, investigations, or how people make decisions will help you connect deeply with the purpose behind the product. We also believe you´re someone who takes initiative, communicates clearly, and isn’t afraid to stand by your ideas- while staying open to others.

Key skills and experience

• Solid experience with AI systems and language models.
• Strong understanding of data platforms and how to design for scale and performance.
• Ability to turn AI output into valuable full-stack applications.
• Proficiency in software architecture, with focus on quality, resilience and maintainability.

Desirable skills

• Interest in investigative methods, forensic psychology, or related fields.
• Ability to communicate complex concepts clearly in writing and verbally.
• A natural enthusiasm for this industry- you can confidently explain why this product matters.

• Ability to clearly communicate your expectations to others, set mutual expectations, and confidently seek assistance when needed.

You may not tick every box, but if you're driven by the same purpose and believe in what we’re building, we’d still like to hear from you.

Why join us?

At Davidhorn, we’re not just building software-we’re building tools that help real investigators make better decisions in complex, high-stakes situations. When someone’s freedom, safety, or reputation is on the line, the quality of an investigation matters. And the tools behind that investigation matter too.

You’ll work on technology that’s directly used in interview rooms, case reviews, and frontline investigations across more than 40 countries. We have strong traction, a growing customer base, and the trust of police forces, prosecutors, and oversight bodies. That trust has been earned over years- and it's what gives us the mandate to do more now.

We believe the future of investigative work is not fully human, nor fully automated-but collaborative. That’s why we’re applying large language models and other AI technologies not to replace human judgment, but to support it: to reduce friction, surface what matters, and help professionals move with clarity and speed.

We’re backed by committed, long-term owners who believe in the mission and in building for the long haul-not chasing short-term gains. And we’re just getting started.

If you want to work on something that touches real cases, real lives, and real decisions-and you want to help shape how technology can responsibly support justice-we’d like to hear from you!

Tech-Stack includes, but is not limited to:

PostgrSQL, Python, Svelte, PHP, Golang, C++, Kubernetes, Azure, Svelte, Svelte Kit, .NET, Kotlin, Swift
