Job description

At Gen25 we are looking for an experienced Senior Salesforce Developer (5+ years of hands‑on development experience) to play a lead role in our London delivery team.

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. Working alongside Architects and Consultants, you will help set development standards, mentor junior team members, and ensure high‑quality delivery across demanding client projects.

Key Responsibilities

• Technical Architecture & Development: Design and build end‑to‑end, scalable custom solutions using Apex (applying enterprise design patterns), Lightning Web Components (LWC), Flow, and complex SOQL/SOSL queries.
• 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.
• Front‑End & UI: Extensive hands‑on experience building modern UI components with Lightning Web Components (LWC) and Aura.
• 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.
• Advanced Certifications: Salesforce Platform Developer II, Platform App Builder, Integration Architect, or Application Architect credentials.
• Cloud Specialities: Practical experience with Salesforce Data360, Service Cloud Voice, MuleSoft or AWS integrations.

What We Offer

• Senior Leadership Pathway: Opportunity to shape technical standards, lead major enterprise projects, and influence ways of working.
• Certification & Continuous Learning: Support and study time to attain official Salesforce and AWS certifications.
• Hybrid Working Model: Flexible blend of home working (3 days a week) and collaborative team days at our London office (2 days a week).
• Agile, Inclusive Culture: A collaborative, challenge‑driven consultancy environment with flat hierarchies and high autonomy.
• Competitive Package: Excellent salary package, pension contributions, 25 days annual leave plus bank holidays, and regular team socials.
