Senior Salesforce Developer (m/w/d)
40,000 buyers. 20+ countries. One Salesforce org carrying all of it. You'll own the two-way sync between Salesforce and our core platform — and the migration off Aura and Visualforce that's been waiting for someone senior enough to do it properly.
Location: Remote from anywhere in Brazil — freelance contract, with your day starting at 7:00 AM Brazil time (12:00 CET) for overlap with the European team.
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 responsibilities
- You own the two-way synchronisation service between Salesforce and our core platform
- You build new features from scratch and continuously improve the existing codebase — hands-on coding, not configuration
- You translate business and user requirements into scalable Salesforce solutions, working with a distributed engineering team
- You take on underutilised platform features and cut technical debt
- You identify and resolve technical issues, optimise system performance and secure data integrity
- You mentor team members and keep technical documentation accurate and current
- You assess new Salesforce ecosystem releases and decide what's relevant for our platform
What you bring
- 5+ years of hands-on Salesforce development, most of it writing custom code rather than configuring
- Deep command of Apex, LWC, JavaScript, HTML5 and CSS — plus the confidence to work in the Aura and Visualforce code you'll be migrating away from
- Strong SOQL, SQL and relational data modelling, and a solid grasp of event-driven architecture where Salesforce meets external systems
- Strong knowledge of SFDC Flows, Metadata API and Salesforce APIs, working within release management and Scrum
- AI-native working style — you use coding agents and LLM tooling daily and have real judgement about where they accelerate you and where they don't
- English at C1 level or above, and an established entity in Brazil able to invoice in euros
Nice to have
- Salesforce certifications
- Experience with Agentforce or Einstein AI features
- Spanish as an additional language
What you get
- Fully remote from anywhere in Brazil on a freelance contract
- Architecture ownership from day one
- An engineering culture where AI tooling is embedded in how the work gets done
- Direct access to the European engineering team — no client-vendor layer in between
- Initial 12-month contract with possibility of extension
- Competitive hourly rate aligned with senior market rates
