About the role
You don't want to be the architect who only draws the diagram. You want to design the integration, write the Apex, review the pull request — and set up the AI tooling so the whole team ships cleaner code by default. Here you do all of it, in an established Salesforce team that runs a mature org.
Location: Central Berlin — you work from our office, hybrid with 2 days in the office and 3 days from home.

Your role • You own the team's Salesforce architecture: you decide where declarative tools fit and where code does, and you build the scalable, well-tested solutions yourself. • You lead solution design. You simplify complex decisions, write down the reasoning and turn it into patterns the team reuses. • You pay down tech debt in a mature org. Fewer moving parts, more tests, smaller changes. • You align engineering, product and business teams on the Salesforce roadmap and drive cross-functional initiatives through to delivery. • You raise the quality bar through code review, pairing and onboarding, and you mentor engineers into owning their decisions. • You set the team's standard for AI-enabled development: shared skills, prompts, project instructions and guardrails that make everyone's AI output follow house conventions. • You translate product and business goals into a Salesforce strategy and shape the team's scope and hiring as it grows.
What you bring • 10+ years in software engineering, with deep hands-on Salesforce expertise across Apex, LWC and Flows — and a clear sense of when to use which. • Solid Salesforce data modelling and integration experience: REST APIs and event-driven patterns such as Platform Events, designed for reliability with retries, idempotency and monitoring. • Broad engineering foundations, including backend services, databases and microservices. • CI/CD for Salesforce (e.g. Gearset, Copado) and strong command of your tooling — Salesforce CLI, Git, static analysis — plus the drive to automate team workflows. • A track record of improving mature orgs and codebases, staying with your systems long after go-live, and making the engineers around you better. • Clear communication with engineering, product and leadership, in English at C1 level.
AI-enabled building • You use agentic coding tools (e.g. Claude Code, Cursor, GitHub Copilot) across investigation, design, implementation, testing and review — and you can explain where they save time and where they cost it. • You connect AI assistants to the team's real tools — code, org metadata, tickets, documentation — through MCP servers or the Salesforce CLI, with guardrails in place. • You review AI-generated code as rigorously as human code. Tests, static analysis and deploy validation catch invented field names, assumptions the org doesn't support and changes bigger than they need to be. • You've designed or evaluated LLM-powered features (e.g. Agentforce or LLMs via API), including when fixed rules should decide, evaluation and monitoring, fallbacks when the model fails, and GDPR requirements.
Nice to have • Experience with agile delivery (Scrum, Kanban) and Jira and Confluence.
What we offer • Hybrid working: 3 days in office, 2 days remote – plus 25 "Work from Anywhere" days per year • 28 days annual leave • 2× annual career & development conversations • Company pension with 20% employer contribution • Fully paid Deutschlandticket (public transport) • FitX membership or Urban Sports Club subsidy • Virtual stock options — share in the upside • Modern IT setup for your day-to-day work • Structured onboarding with buddy programme and social events • Lived diversity: active women's network, meditation & prayer room
