Junior Software Engineer jobs in United Kingdom

🌍 Join Triptease — Where Travel Tech Meets Impact. At Triptease, we’re building technology that helps hotels thrive in a digital world dominated by Online Travel Agents. Our products empower hotels to increase direct bookings, regain profitability, and build closer relationships with their guests. Already helping generate over £1 billion in direct revenue annually, we’re scaling fast across 100+ countries with offices in London, New York, Barcelona, and Singapore. It’s a fantastic time to join us as we grow our impact and expand our engineering teams. We’re a team that values authenticity, ownership, inclusion, and delivering meaningful work — together.

We’re looking for a Mid Level Software Engineer who thrives in solving complex problems, working closely with others, and experimenting with new technologies. You will have excellent experience with backend projects and have also worked as a full stack engineer. You’ll help us craft accessible user experiences, design scalable systems, and explore how AI and automation can make our platform smarter and more impactful for hoteliers worldwide.

Tamarin looks after Triptease’s core off‑site marketing channels: Metasearch, Paid Search and Retargeting. Our mission is to empower hotels with control over these channels, giving them the tools to shape strategy, reach their most valuable guests and drive direct bookings. We’re a collaborative team working mainly in TypeScript (Node.js and React) with Google Cloud Run, Kubernetes, Terraform and BigQuery. Day‑to‑day we build backend services, integrations with platforms like the Google Ads API, and features within Campaign Manager that give hoteliers both strategic control and tactical flexibility. Our main challenges include unifying channels into a connected system, balancing automation with customer control, and staying ahead of the fast‑changing Google ecosystem. We value continuous learning, autonomy and product thinking; every engineer contributes ideas and helps shape the squad’s direction, not just the code.

• Languages: Primarily TypeScript, with some Kotlin and Python
• Backend: Node.js, experimenting with modern alternatives like Bun
• Frontend: React for admin tools and reporting (minimal UI work)
• Infrastructure: Google Cloud Run, Kubernetes, Terraform
• Data: BigQuery, PostgreSQL, MySQL
• Integrations: Google Ads API, various metasearch and advertising platforms

You’ll be part of a small, empowered squad responsible for building, growing, and maintaining key parts of the Triptease stack. While the work spans both frontend and backend, there’s a strong lean toward backend systems.

• Pair program with teammates for the majority of your coding time
• Take part in daily standups, weekly planning sessions, and frequent retros to continuously improve how we work
• Collaborate openly with colleagues — we value honest discussion and make sure everyone’s voice is heard
• Contribute to a team that owns its strategy end‑to‑end, deciding together what actions to take to succeed
• Practice trunk‑based development and continuous delivery, shipping small, incremental changes to production

• XP Engineering Practices: Comfortable with pair programming most of the day, and see test‑driven development (TDD) as integral to building reliable systems. You use tests to drive design, embrace refactoring as part of everyday coding, and value small, incremental code and test cycles.
• Backend and Full‑Stack Experience: Strong backend experience in TypeScript with additional frontend skills for admin UIs. Solid skills across the full stack, from client‑side to server‑side development.
• Cloud‑Native Experience: Practical experience building deployment pipelines and continuous delivery on cloud platforms. Familiarity with Google Cloud Platform, Docker, Kubernetes, and Terraform.
• Data Systems and Analytics: Experience with PostgreSQL, MySQL, and BigQuery. Passion for working with data to power real‑time analytics, A/B testing, and monitoring with tools like DataDog.
• Systems Thinking: Experience designing and building distributed, high‑availability, high‑throughput systems while maintaining modularity, functionality, maintainability, and data consistency. Solid understanding of HTTP and how the internet works.
• Code Quality: You write obvious, concise code that rarely needs comments and always leave the codebase better than you found it.
• Product Mindset and Collaboration: Customer‑centric approach, working closely with product managers to ensure technical solutions deliver value. You contribute ideas and strategy, not just code, and thrive in collaborative environments that drive squad momentum.
• Values Alignment: Commitment to continuous learning, autonomy, psychological safety, and developing your craft.

• Experience with online advertising or ad tech products
• Familiarity with the Google Ads API
• gRPC experience (we maintain a TypeScript Google Ads API library)
• You have an entrepreneurial streak, with examples of how you identified opportunities and delivered them
• Experience in cross‑functional teams practising XP (Extreme Programming) and Kanban techniques
• Familiarity with multiple programming languages and the ability to bring insights and practices across ecosystems

• We’re committed to your career development, most of our staff have seen considerable learning and progression. There is space to take dedicated learning time out each week to further improve your craft. Triptease will also fund training and conferences if you tell us why we should.
• We like to offer all our employees a stake in our success which is why we offer share options.
• Paid vacation (increasing with tenure)
• Work from anywhere: 4 weeks abroad annually (within a ±3 hour time zone)
• Monthly wellness budget – use it for gym, therapy, massages, or whatever keeps you at your best
• Yearly learning allowance – invest in your growth!
• Enhanced maternity & paternity leave
• 10 “Discovery Days” per year to explore innovative ideas together with colleagues from around the business
• Fun events for Tripteasers – the entire company is travelling to Madrid this September for a global retreat
• Whatever equipment helps you get your job done

• In Product‑Engineering, we hire people we trust, and then trust them to make their own choices on how they want to work, and how they want to reach a goal. This sounds simple but it requires a lot of investment in the right company culture. Our team is made up of autonomous squads who decide what they work on, how they work and within them have all the skills they need to complete their mission. That means we have no centralised teams (Ops, QA etc).
• We think that we are doing a good thing for hotels and guests and believe in our mission! We are working on a highly scaled platform that hotels use to build direct relationships with their customers and cut out middlemen. In terms of scale, our software operates on over 10k hotels and collects 30M guest events a day, and growing. That’s a big opportunity to positively impact a lot of people.
• We engage with our customers to validate assumptions and test new features. We like to go crazy deep on the problem. “Start with the problem” is one of our three core principles, and beyond tools like FullStory, Intercom and Analytics that help us learn about users, each squad has friends in CS and Sales and even hoteliers themselves to help build that knowledge. Hotel visits and travel research budgets are also a big plus.
• We care deeply about diversity and inclusion. We have a dedicated D&I squad who meet regularly to work on and propose actions to improve D&I within the team and wider biz. Outside of hiring activities, we work hard to foster an environment of psychological safety. We truly value collaboration and are invested in maintaining a team that encourages everyone to contribute.
• We optimise for learning. We regularly provide each other with feedback and reflect on the ways we work. We use Notion to bring efficient transparency and create a home for everything we do. We have initiatives like “Discovery Days”, “Field Trips” and “Product Management Dojos” to bring new people together and create more learning and development opportunities.
• We celebrate our progress. At the end of each week, we join the rest of the company to showcase what we’ve accomplished and share our pride in the work we have done with our colleagues.

Triptease is proud to be an equal opportunity employer with an active cross‑functional "diversity squad" devoted to addressing diversity challenges in the company and industry.
