hackajob is partnering directly with Sage to hire for this role. We're hiring | Senior Salesforce Developer - Product Engineering Team (ISV) in Winnersh (Reading area), 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
What really makes this role stand out is the team.
- 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
