Software Engineer in London

We have an exciting opportunity for a Software Engineer to join Attest and help us build the foundations for the next evolution of the Attest product. You’ll focus on the core engineering building blocks that enable our teams to move fast: architecture, internal APIs, data models, and reliable, scalable foundations. Whether you come from a backend or full-stack background, what matters most is your depth in engineering fundamentals and your ability to design and build practical, robust systems in ambiguous, early‑stage settings. You’ll work in a cross‑functional squad alongside Product, Design and Data Science, using a modern stack including Java, Python, Kafka, VueJS and Postgres, as well as integrations with external providers. Collaboration is key at Attest—our teams work closely with stakeholders across the business to deliver meaningful value for customers.

Salary: We are able to offer between £65–85K depending on experience.

In person and remote working balance: We embrace a flexible hybrid work model. While we don’t mandate specific office days, we ask Attesters to work on‑site 2 days per week. This approach allows us to collaborate in person, while ensuring enough time remotely for deep, focussed work.

What You’ll Be Doing…

• As a Software Engineer, you will work within a squad to create best‑in‑class foundations for our product.
• Work effectively within today’s core frameworks and data models, contributing improvements and proactively recommending changes where different approaches would better serve scale, performance, or product needs—while maintaining overall architectural integrity.
• Design, build, and maintain REST APIs and web services that are reliable, secure, and easy to evolve.
• Proactively identify, debug, and fix bugs, while driving initiatives to reduce technical debt and improve long‑term code quality.
• Build and evolve architecture, internal APIs, data models, and system patterns that support fast product development.
• Collaborate on the design of scalable, performant, secure system architectures, with a practical, hands‑on approach rooted in real experience.
• Contribute actively to planning, stand‑ups and retros, helping guide discussions and remove blockers.
• Bring curiosity to your work, continuously learning and applying new ideas, tools, and approaches to improve how we build and operate software.
• Work comfortably in ambiguity, focusing on practical solutions that deliver impact quickly.

What You’ll Bring…

• Come from either a backend or full‑stack background and want to deepen your impact on core engineering foundations.
• Have worked with Java.
• Be energised by and have experience of working in start‑ups or scale‑ups where you have solved early‑stage challenges and built practical solutions that unlock speed at scale.
• Be curious and pragmatic about AI in software development, eager to experiment with new tools that help teams move faster and build better products.
• Like solving problems by keeping systems simple and effective.
• Thrive in collaborative, cross‑functional environments.

Our benefits:

• Work from anywhere up to 20 days a year.
• 25 days holiday per year plus additional festive days.
