Make An Impact.
Fundamentally, people do their best work when they can see its impact. We don't like hiding in the shadows; we want to do highly impactful, meaningful work for a company that is solving some of the world's biggest problems.
Learn Faster.
We’re addressing issues no one has before - that means we have to learn quickly and iterate readily. We support you with tailored development plans to help you thrive in your role and keep growing.
Go Further.
We believe working for Tessian is a rare career opportunity, which we want to be experienced by a diverse team. The contributions you make here will accelerate your career at an unusually fast pace.
Our Values.
Securing businesses, people and their data is critical work. We make sure that everyone that joins our team not only shares our mission for securing the human layer, but also our values, which define the way we work.

  • Human first.

    We approach everything with empathy and we look out for each other alongside our own wellbeing. Respect, kindness and inclusion are at the core of our company because our people are what make us Tessian.

  • Customer centricity.

    We fixate on our customers’ success. They’re the lifeblood of our business and guide our daily decision-making. Whether we’re launching a feature, or pursuing a partnership, we always ask “How does this help our customers?”

  • Positive mindset. Solution oriented.

    We lead with a curious, positive mindset, and go above and beyond to find solutions when problems arise. When our solutions fail, they fail fast — we embrace the failure and keep learning, iterating, and improving.

  • Grit and perseverance.

    We have sustained passion for achieving long-term goals. We see setbacks as opportunities to adapt and grow. We’re committed to building the resilience and motivation to tackle big challenges that others might give up on.

  • We do the right thing.

    We’re always honest and guided by integrity in every decision we make, with one another, with our customers, with everyone. We do what we believe is right, even when it means making difficult decisions.

  • Craft at speed.

    We work with great care and skill, sometimes at an uncomfortably fast pace. Rather than aim for perfection in one at the expense of the other, we balance attention to detail with speed of delivery.
