Senior Fullstack Engineer | Remote

About us

Pickle is a business enablement service. We provide fractional, embedded, human-led support across the functions that quietly keep growing businesses moving. EA and executive support, admin, customer support, operations, bookkeeping, talent placements and HR.

We work alongside founder and operator-led businesses at the moments when they need more capacity, more structure, or more support than they currently have. Our people embed into client businesses and take genuine ownership of the work. No task-ticking, no arm's-length delivery. Just real judgement and follow-through.

• Influence architecture decisions across APIs, event-driven systems and shared platform services.
• Design reusable backend services and scalable architecture to support future product growth.
• Champion engineering best practices through clean, well-tested code and thoughtful code reviews.
• Mentor junior engineers and contribute to a collaborative engineering culture.
• Partner closely with Product and Design to define practical technical solutions.
• Work autonomously while keeping stakeholders informed and aligned.
