Staff Software Engineer in London

At TixTrack, we support our clients by creating superior ticketing solutions for performing arts and cultural institutions through a combination of modern technology, beautifully simple design, and the art of listening. Founded in Los Angeles, we are a small, but growing team of hardworking, highly motivated individuals. Our core product, Nliven, is a real-time platform that helps venues manage ticket sales efficiently while creating a more engaging buying experience for customers. With a presence across both the US and UK, and trusted by key organizations on Broadway and the West End, we are passionate about our work and driven to innovate with our customers to solve current and future challenges with new solutions.

We are transforming our engineering culture to align with an Empowered Teams model, embracing Continuous Delivery and focusing on building capabilities to drive higher quality, reliability, and speed. Even with a highly dispersed, largely remote workforce, we stay connected through our Slack channels, virtual events and regional meetups.

The Staff Software Engineer is a key technical leader and mentor in our UK engineering organization. This role is responsible for driving modernization of our core product by architecting, developing, and optimizing both frontend and backend systems with a relentless focus on quality, reliability, and architectural excellence. This role requires deep expertise in .NET Core and modern frontend frameworks (React, Angular, or Vue) to build scalable, high-performance applications. It also requires a deep appreciation for the principles of Site Reliability Engineering (SRE) and DevOps to ensure our systems are stable, observable, and rapidly deployable.

Beyond technical execution, this position is a force multiplier; you will mentor engineers, assist the team in adopting Continuous Delivery practices, and ensure engineering best practices. The Staff Software Engineer plays a pivotal role in system design, risk assessment, and deployment strategies while partnering with Product, Design, and Engineering Leadership to deliver solutions as part of a cross‑functional, empowered product team.

You have a strong background in .NET Core and modern frontend frameworks like React, Angular, or Vue, with a deep understanding of both backend and frontend development. You don’t just write code; you mentor, assist, and collaborate with your peers to elevate the entire team’s technical output and skill level. You thrive on the challenge of modernizing an established product and are skilled at designing and building independent services to enable team autonomy and faster delivery. You have experience taking ownership of large‑scale projects, driving architectural decisions, and mentoring junior engineers to foster a culture of technical excellence and continuous learning. You thrive on solving complex challenges related to performance, scalability, and security, ensuring reliable and high‑performance applications. You are comfortable partnering with Product, Design, and Engineering Leadership to deliver technical solutions that align with business goals as a member of an Empowered Product Team.
