About the Role

We are looking for a product-focused Senior Software Engineer to join our Experiences Engineering team. This is a full-stack role, leveraging Java, SQL, React, AWS and AI tools. You'll build and maintain highly scalable distributed systems that power travel experiences for millions of users globally.

You can expect a remote-first working model with periodic in-person gatherings at your closest office for team connection, planning, or other key moments. This position is open to candidates based within a commutable distance (generally up to 1.5 hours) of one of our office hubs in London, Oxford, Krakow or Lisbon.

• Lead Technical Design: Own features end-to-end, leading the design and implementation of highly visible features while balancing security, privacy, and performance.
• Translate Strategy to Action: Work with Product and Data partners to turn high-level business goals into clear technical specifications, often serving as the technical lead for multi-quarter initiatives.
• Elevate the Team: Set the bar for code quality, lead the adoption of review standards, and mentor junior and mid-level engineers.
• Master Agentic AI: Use AI tools as a strategic partner to plan approaches, decompose ambiguous work, and establish new standards for monitoring and reliability.
• Architect for Resilience: Define the operational strategy and design highly fault-tolerant architectures, proactively identifying structural risks and setting the team-wide standards for automation, monitoring, and long-term stability.
• Actively look for opportunities to simplify, consolidate, or retire legacy code to reduce complexity and increase team velocity.

Skills & Experience

We typically look for 5+ years' experience, following a Bachelor's degree or above in Comp Science or a related field.

• Distributed Systems Expertise: Deep understanding of concurrent programming and experience building high-performance, scalable backend systems in cloud environments.
• Full-Stack Proficiency: Strong experience in at least one modern backend language (e.g., Java, C#, Go, Python) and familiarity with modern front-end frameworks.
• AI Coding: You are fluent coding with either Cursor or Codex/Claude/Open Code.
• Experience with NoSQL databases, GraphQL, Kafka, or containerization (Docker/Kubernetes) is a plus.
• Experience building tools or abstractions that provide leverage to an entire engineering team is also a significant plus.

You can complete our coding interview exercises in any language of your choice, but need to be open to working within the Java ecosystem when you join!
