Our Team

At Trilitech, our mission is to power the Web3 revolution by facilitating the development of cutting‑edge solutions on the Tezos blockchain. We specialise in Core Development, Application Development, Tooling & Infrastructure, Developer Experience, and Incubation & Acceleration across three key areas: Culture, Decentralised Finance, and Gaming. We’re committed to pushing the boundaries of what’s possible and continue to set new standards in this ever‑evolving space.

Our Technology

Tezos is an open‑source platform known for its flexibility, security, and self‑amendment capabilities. It’s built to empower developers to create smart contracts and decentralised applications with ease. Today, the Tezos ecosystem is made up of thousands of passionate community members actively involved in various projects and initiatives including the development of decentralised applications, smart contracts, and educational content. We’re proud to partner with the likes of Manchester United, Ubisoft, and Societe Generale (to name a few). Some of the exciting projects built on the Tezos blockchain are hash, Objkt.com, Kord.fi and Kukai.

We encourage you to explore the Tezos website and follow us on Twitter & Discord to learn more about the project.

• Experience working with React Native mobile development projects
• Strong computer fundamentals (e.g., algorithms, data structures and concurrency)
• Creative problem‑solving skills, with the ability to develop innovative solutions to complex problems
• Experience developing user‑friendly interfaces in a product environment
• Excellent interpersonal and communication skills, with the ability to work as part of a collaborative team
• Familiarity with best practices in software engineering, including version control, code review, and continuous integration

What you can expect from us

• Generous LTIP tez token scheme
• Flexible hours and a hybrid working environment; work from home and our dog‑friendly office in Soho with access to an onsite gym and media room
• Lunch delivered daily in the office (Dishoom, Honi Poke, Salad Kitchen - you name it, we’ve tried it!)
• Expense up to £2700 per annum for subsidised commuter costs
• 20 day working abroad policy
• 25 days paid holiday and an additional day to celebrate your birthday
• Enhanced parental & adoption leave to support you in your journey through parenthood
• We’ll double match your pension contribution (allowing you to contribute up to 5% of your gross salary, with us contributing up to 10%)
• Private medical insurance with Bupa from day one, inclusive of mental health support
• Learning and development initiatives to empower you in your career
• Comprehensive life assurance policy of 5x your base salary to provide you and your loved ones with peace of mind

Why you’ll love it

Our cutting‑edge projects offer you a chance to lead the way in shaping the future. We are dedicated to keeping your enthusiasm alive by fostering a fulfilling work environment that encourages open conversations and creativity. Collaboration and mutual support is key!

Our commitment to work‑life balance ensures you have the time and energy to excel in your role while still enjoying life beyond the office. We offer competitive compensation, an extensive benefits package, and ongoing development opportunities, empowering your personal and professional growth. We’ll chat more about this throughout the interview process.

We believe in hiring great people and granting them the flexibility to work in a way that suits them best. While we establish OKRs, you’ll have the autonomy to determine your approach. Given the incredibly fast rate the blockchain landscape is evolving, embracing a growth mindset and a commitment to continuous learning are integral to our culture. It’s okay not to have all the answers and to engage in research. We’re all human and we provide formal perks to support your ongoing education.

Our Principles

• Desire to Win In our highly competitive industry, success is all about being at the top of our game. We strive for excellence and aim to be the best.
• Sense of Urgency Adaptability and quick action are essential in maintaining a competitive edge. We thrive on staying ahead of the curve.
