Job Description

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
