Job description

We’re hiring | Senior Salesforce Developer – Product Engineering Team (ISV) in Winnersh (Reading area) or Newcastle, UK | Hybrid (3 days onsite)

Sage People is a global HR & people management SaaS product built on the Salesforce ( Force.com ) platform, serving customers worldwide. As an ISV, we build and evolve one single product, with a strong focus on code quality, scalability, performance and long‑term architecture.

We’re looking for a senior hands‑on Salesforce engineer who can go beyond feature delivery: someone able to understand business complexity, shape technical design, contribute to architecture decisions, and help build scalable, maintainable solutions within a mature Salesforce product environment.

Team culture & environment

• A stable, close knit engineering group — many team members have worked together for 8+ years
• A friendly, supportive and human environment, where people genuinely enjoy working together
• Engineers, testers, architects and product managers collaborating daily as one product team
• A culture that values shared ownership, learning and constructive technical discussions
• Strong leadership momentum and investment, particularly around AI and Salesforce innovation
• A modern, welcoming office in Winnersh, with teams enjoying face to face collaboration as part of a hybrid model

What you’ll be doing

As a Senior Salesforce Developer, you will take ownership of complex technical delivery while contributing to the design and architecture of our Salesforce-based product. You will work hands‑on with Apex, SOQL, JavaScript, Salesforce Lightning, Lightning Web Components, VisualForce and APIs, while helping define robust technical approaches for scalable product features.

• Design, develop and maintain enterprise‑grade Salesforce product features with a strong focus on scalability, maintainability and performance
• Translate complex business requirements into clear technical designs and robust implementation plans
• Contribute actively to Salesforce architecture discussions, design reviews and long‑term product decisions
• Apply strong object‑oriented design principles, automated testing practices, code quality standards and CI/CD ways of working
• Mentor and support other engineers through code reviews, technical guidance and knowledge sharing

This is a senior hands‑on development role with genuine technical depth. It is not an admin or configuration‑focused position: we are looking for someone who enjoys building, designing and improving complex Salesforce product capabilities.

What we’re looking for

Core skills

• Strong hands‑on Salesforce development experience, ideally within a product, SaaS or ISV environment
• Advanced knowledge of Apex, SOQL, JavaScript, Salesforce Lightning and Lightning Web Components
• Good understanding, and ideally practical experience, of Salesforce solution design and architecture
• Ability to design scalable, secure and maintainable solutions while considering Salesforce platform limits, data model, integrations and performance
• Solid object‑oriented programming background, for example in Java or C#, with strong software engineering fundamentals

Nice to have

• Experience contributing to architecture reviews, technical roadmaps or design governance
• Exposure to Salesforce REST APIs, integrations and enterprise application architecture
• Experience with Git, Jira, IntelliJ, CI/CD pipelines and automated testing strategies
• Salesforce Platform Developer certification, or architecture‑related Salesforce certifications
• Interest in AI‑driven product capabilities and how they can be embedded into Salesforce‑based solutions

Benefits – we have plenty

• Competitive salary plus generous bonus scheme
• Pension plan: up to 8% matched + 2% top‑up by Sage
• 25 days annual leave, with the option to buy up to 5 more
• 8 bank holidays
• 5 paid volunteer days per year via the Sage Foundation
• 50% income protection
• Holiday buy & sell
• Comprehensive health, dental and vision coverage
• Work Away scheme (up to 10 weeks per year)
• Ongoing training and professional development
• Hybrid working
• Healthy Mind app membership
• Access to financial, health and wellbeing memberships
