About the role
Passionate about building great software and excited by what AI can bring to modern engineering? If so, we'd love to hear from you! Haven is looking for a Senior Engineer to join our talented Technology team, playing a pivotal role in shaping how we design, build and evolve the digital products behind memorable holidays for millions of guests.
As a Senior Engineer, you’ll be a “go to” person within your squad, bringing deep technical expertise to both hands-on delivery and the wider engineering approach. You’ll define how features get built, drive them through to completion, and help others grow along the way. Around 80% of your time will be hands-on engineering, with the remainder spent guiding, mentoring and shaping technical direction.
This is a fantastic opportunity for an engineer who’s excited by the current AI-driven shift in software development, keen to embed AI capabilities across the engineering life-cycle, and eager to help evolve how a modern team plans, designs, builds and validates software.
