Senior Software Engineer (Platform & Backend)

Open 29d

Alongside is a Portuguese company that partners with international organizations to build and scale exceptional tech teams.

Our client is a fast-growing SaaS company transforming the automotive dealership experience by automating administrative processes, streamlining sales workflows, and ensuring compliance.

They are looking for a highly experienced Senior Software Engineer (Platform & Backend) to join their fully remote team. This is a hands-on engineering role for someone who enjoys solving complex technical challenges, taking ownership of architecture, and leading technical initiatives across the entire stack.

This is not a people management role. Instead, you’ll act as a technical leader, driving architecture, owning critical parts of the platform, and leading projects from design through production.

Responsabilities:

  • Own and evolve major parts of the application architecture.
  • Design, build and maintain scalable software across backend, frontend and infrastructure.
  • Lead technical projects from design through production.
  • Make architectural decisions and drive technical direction.
  • Build and operate production systems with a strong focus on reliability, scalability and performance.
  • Review code and promote engineering best practices.
  • Troubleshoot production issues and improve platform resilience.
  • Collaborate closely with product and engineering teams to deliver high-impact features.

Requirements

  • Extensive experience building and scaling SaaS products.
  • Strong expertise in TypeScript, with solid experience across backend, frontend and cloud infrastructure.
  • Strong backend engineering experience.
  • Experience operating and maintaining production infrastructure in cloud environments.
  • Proven experience designing software architecture and leading technical projects.
  • Previous experience as a Tech Lead, Staff Engineer, Principal Engineer or Senior Software Engineer with architectural ownership.
  • Comfortable working across the full stack and taking ownership from infrastructure through backend to frontend.
  • Experience with AWS, Pulumi, Bun, React, Vite, GraphQL, PostgreSQL and Redis is a plus.
  • Excellent communication skills and the ability to work autonomously in a fast-paced startup environment.

Benefits

  • Fully remote, based in Portugal.
  • Salary range: 50k – 80k per year
