In this role, you will lead the technical design, build, and deployment of complex Salesforce solutions across multi‑cloud environments. You will combine deep technical expertise in Apex, Lightning Web Components (LWC), and system integrations with strong client‑facing acumen and team leadership.

- Integrations & Middleware: Architect and implement secure REST/SOAP APIs, webhooks, and custom callouts (utilising OAuth, JWT authentication) to integrate Salesforce with third‑party systems.
- Technical Leadership & Mentorship: Conduct rigorous peer code reviews, enforce coding standards and security best practices, and actively promote best practices amongst the team.
- DevOps & Release Management: Drive modern Application Lifecycle Management using Git, Salesforce DX (SFDX), and CI/CD deployment pipelines across multi‑tier sandbox topologies.
- Solution Strategy: Evaluate client requirements to balance declarative ('clicks') and programmatic ('code') approaches, ensuring solutions are performant, maintainable, and aligned with standard platform capabilities.
- Client Engagement: Participate in client workshops, technical discovery sessions, and solution demos, translating complex technical concepts into clear business language for stakeholders.
Requirements & Prerequisites
- Experience: 5+ years of hands‑on technical development experience on the Salesforce platform, ideally within a consultancy or fast‑paced enterprise environment.

- Integrations: Proven track record of designing and executing complex API integrations (REST, SOAP, JSON, Event‑Driven Architectures).
- DevOps & Tooling: Proficient with Git‑based version control, SFDX, metadata deployment pipelines, and automated testing frameworks (>85% code coverage standards).
- Certifications: Must hold Salesforce Platform Developer I (Platform Developer II strongly preferred) and other relevant certifications.
- Communication & Leadership: Strong stakeholder management skills with the ability to lead technical discussions, estimate project effort, and mentor peers.
- Right to Work: Eligibility to work in the UK.
