Job description

Overview

Senior Software Engineer– Permanent - £47,000 - £58,760

Join us and be part of a mission-driven, independent publisher. You’ll work with a diverse group of people who share a passion for empowering researchers, educators, and institutions to shape the future.

About Sage:

Sage is a global academic publisher of books, journals, and library resources with a growing range of technologies to enable discovery, access, and engagement. Believing that research and education are critical in shaping society, Sara Miller McCune founded Sage in 1965. Today, we are controlled by a group of trustees charged with maintaining our independence and mission indefinitely.

Our guaranteed independence means we’re free to:

• Do more– supporting an equitable academic future, furthering disciplines that drive social change, and helping social and behavioural science make an impact
• Work together– building lasting relationships, championing diverse perspectives, and co-creating resources to transform teaching and learning
• Think long-term– experimenting, taking risks, and investing in new ideas

About our Team:

We are a collaborative, motivating engineering team. Our focus is on building robust systems while creating an environment where everyone can thrive. To help us maintain high standards, we have linting, pre-commit checks, unit tests, warn-as-error policies, and SonarQube quality gates in place - all designed, so we can concentrate on writing great code without distractions.

Openness and teamwork are at the heart of how we work. When challenges arise, we look for process improvements rather than placing blame, and we learn and grow together by sharing knowledge across the team.

Our team builds and maintains Sage’s flagship content delivery platforms - Sage Research Methods, Sage Video, Sage Business, Sage Books and Reference, Sage Skills - which play a critical role in enabling students, researchers, and academics around the world to access and engage with trusted content.

We partner with Product and QA, and are actively driving adoption of Gherkin across both product development and automated testing. We’re also at the forefront of Sage’s company-wide rollout of Claude Code, ensuring our engineers have access to innovative AI tools and training to support their work.

Could you be our new Senior Software Engineer? Are you?

• A highly skilled engineer who is proficient in full-stack development, with significant experience in Microsoft technologies and cloud platforms (ideally Azure). Our core stack includes .NET 9, C#, MS SQL, Vue.js, JavaScript, and TypeScript, so experience in some or all of these areas will set you up for success.
• Able to break down challenges, design scalable solutions, and continually improve existing systems.
• Confident in working across teams, building strong relationships, and contributing positively to Agile ceremonies in a remote environment.
• Focused on writing clean, robust, and efficient code, while maintaining high standards of quality.
• A natural inclination to mentor peers, share knowledge, and influence team success beyond your own contributions.

Your new role:

As a Senior Software Engineer, you’ll play a key role in shaping the technical direction of our publishing systems. You’ll design and build sophisticated solutions that enable content delivery, access control, analytics, and other critical business functions. Beyond hands-on coding, you’ll contribute to architecture decisions, champion engineering best practices, and ensure our systems are scalable, secure, and fit for the future.

You’ll partner closely with colleagues across multiple teams, fostering collaboration, sharing knowledge, and helping others succeed. This is not just about delivering features - it’s about driving progress, influencing outcomes, and ensuring the solutions we create are both effective today and sustainable tomorrow.

Overview of benefits:

• 25 days annual leave (plus bank holidays) with 2 additional floating personal days.
• Home working allowance.
• Life assurance, income protection and travel insurance.
• Private medical cover and access to the company doctor.
• Tuition scheme and support for pursuing professional qualifications, including access to Sage books and journals.
• Healthy lifestyle reimbursement and anniversary trips.
