Staff Salesforce Engineer (f/m/x)

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. About us CarOnSale is the AI-powered platform for B2B used car trading in Europe. Over 40,000 buyers from more than 20 countries trade on our platform — and 85% of inventory is exclusive to us. We connect software, pricing intelligence, logistics and financing in one layer — as the operating system for an entire industry. One Platform. One Profit Engine. 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 Apply now — your CV is enough.
