Salesforce Developer (f/m/x)

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.

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

An engineering culture where AI tooling is embedded in how the work gets done
