| AI that’s redefining work for millions
We’re launching a new AI Hub in Portugal to advance Halo, our industry-leading AI platform that helps organisations across Europe turn learning into measurable business outcomes – developing people, boosting productivity, and proving impact at every level.
Be one of the first to shape the future of AI at Kallidus’ Portugal Hub. Build solutions that solve real problems for real people, from day one.
Growing a European leader in outcome-driven AI
Kallidus partners with some of Europe’s most innovative organisations, helping employees learn, grow, and perform better. Our customers span industries, sizes, and countries, which means the AI we build must work at scale, across cultures, and in real operational environments. Your work won’t stay a prototype, it will be relied on by millions of users every day.
We’re growing fast: in people, customers, and ambition. Recognised as #1 in Europe on G2’s Highest Rated Leaderboards for LMS and Corporate LMS, our platform delivers measurable impact: improving performance, engagement, and long-term organisational outcomes.
The next chapter of growth is powered by AI. By embedding intelligence across learning, performance, and development, we make outcomes faster, more measurable, and sustainable. Portugal is central to that vision. Joining today means shaping the future, helping define how we build, scale, and innovate, to deliver real, impactful results that our customers can rely on.

Halo: AI with real-world impact
Halo isn’t an experiment or a side project – it’s central to Kallidus’ platform and strategy
Halo is an AI platform built to solve real organisational challenges at scale, helping companies understand skills, performance, risk, and development, and act on them with confidence.
For engineers, that means:
– Production-ready AI, not prototypes
– Solving real problems, not building “AI for AI’s sake”
– Prioritising reliability, explainability, and lasting impact
– Focusing on quality over hype, thoughtful design over unnecessary complexity, and sustainable practices that benefit users
Joining the Portugal AI Hub means contributing to AI that already delivers measurable value, and helping shape where it goes next, influencing the future of learning and work.
Why Portugal?
Portugal offers exceptional technical talent, a strong engineering culture, and a rapidly growing AI and technology ecosystem. For Kallidus, it’s more than a location, it’s a long-term investment, a place to build, grow, and develop people over time, not a short-term experiment.
This hub will collaborate closely with teams across Europe while cultivating its own identity, culture, and leadership. We chose Portugal not just for talent, but for the engineering values it embodies: thoughtful problem-solving, collaborative teamwork, and pride in craft. It’s the kind of culture that enables AI to deliver real, measurable outcomes, both for our customers and for the teams building it.

The Bulgarian Hub: Proof, not promise
Our technology hub in Bulgaria is a key part of Kallidus’ success story.
What started as a small, focused team has grown into a thriving, highly skilled hub that plays a central role in our engineering and product development.
The Portugal AI Hub builds on this proven model: distributed teams, high standards, strong collaboration, and genuine ownership, not outsourcing.
