Job description

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
• 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
