Job Description


Our client is building the operating system for global mobility. By combining artificial intelligence with a vertically integrated supply chain, they orchestrate every step of employee relocations across 160+ countries. The team is lean, ambitious, and intensely focused on transforming a fragmented, manual industry into a unified platform that delivers a premium, white-glove relocation experience at scale.

About The Role

You will work across product, AI, and infrastructure to design and build the systems that power global relocations for enterprise customers. You'll play a key role in shaping the company's technical foundation as it scales from early traction to robust, platform-level deployments.

Expect close collaboration with product, design, and operations, along with the autonomy to make meaningful architectural decisions and directly influence the direction of the technology.

What You'll Do

  • Own and ship end-to-end product features across backend services, APIs, and frontend applications
  • Build AI-driven workflows and supply chain integrations that power the platform
  • Design scalable data models with Supabase and Postgres, including row-level security for enterprise multi-tenancy
  • Develop intuitive interfaces that make complex relocation data easy to act on
  • Partner with Product, Design, and Operations to turn ambiguous problems into shipped software
  • Contribute to architectural decisions, system design, and engineering standards as the team grows
  • Mentor future engineers and help define the engineering culture

Requirements

  • Fluent English
  • Frontend: TypeScript, React, Next.js
  • Backend: TypeScript, Node.js, Supabase (Postgres, Edge Functions)
  • Infrastructure: AWS, Vercel
  • Auth & Data: Supabase, Postgres, Row-Level Security
  • Tooling: GitHub, CI/CD, analytics and observability
  • Strong fundamentals and product thinking over exact tool match

Core Qualifications

  • You likely have 5+ years of professional engineering experience with meaningful full-stack ownership
  • You've built and shipped production web applications with modern TypeScript or JavaScript frameworks
  • You have strong fundamentals in backend systems, APIs, databases, and data modeling
  • You've owned large features or systems end-to-end, from design through production and iteration
  • You're comfortable in fast-moving, ambiguous environments where scope isn't always defined

What We Look For

  • Full-stack ownership instinct. You naturally pull across the entire stack to ship
  • Strong user empathy and attention to real-world workflows and edge cases
  • Product intuition that goes beyond implementation to ask 'should we build this?'
  • Clear, direct communication across engineering, product, and operations
  • Bias toward shipping, learning, and iterating quickly

Nice to Have

  • Experience with Supabase, Postgres, or serverless architectures
  • Familiarity with AWS infrastructure and deployment pipelines
  • Experience building B2B SaaS or operational software at scale
  • Exposure to AI-powered or data-driven products
  • Early-stage startup experience where you wore many hats

Benefits

  • Your pick when it comes to employment models: CLT/PJ/Cooperativa;
  • We provide the necessary resources for you to grow and learn on the job, the latest-gen laptops, and great ultra-wide, IPS panel monitors;
  • A fully remote work environment with flexible working hours;
  • Bonus for any referrals that we end up hiring;
