Full description

We are looking for a Senior Software Engineer to join an AI-focused engineering team on an initial 6-month contract. The ideal candidate will have strong, hands-on experience with TypeScript and Go, combined with a platform engineering mindset and experience building AI-native or agentic systems.

This is an excellent opportunity for an engineer who enjoys solving complex technical problems and building the platforms, tools, and systems that other engineers rely on.

Key Responsibilities• Design, build, and maintain scalable software systems and engineering platforms.

  • Solve complex engineering and architectural problems beyond simply delivering product features.
  • Develop production-grade solutions using Go and TypeScript.
  • Build internal tools, platforms, services, and infrastructure used by other engineers.
  • Contribute to the development of AI-native and agentic systems and/or the infrastructure that supports them.
  • Work with cloud technologies across Azure and/or AWS.
  • Collaborate with senior engineers and technical stakeholders to design robust and scalable solutions.
  • Contribute to engineering best practices, architecture, reliability, and performance.
  • 5+ years of professional software engineering experience.
  • Strong, hands-on experience with Go (Golang) and TypeScript.
  • Proven track record of solving complex engineering problems, rather than focusing solely on feature delivery.
  • A strong platform engineering mindset, with experience building tools, systems, or infrastructure that other engineers depend on.
  • Hands-on experience building AI-native, AI, or agentic systems, or developing infrastructure/platforms to support AI workloads.
  • Experience working with Azure and/or AWS. Experience with both is a plus.
  • Strong understanding of software engineering principles, system design, scalability, and reliability.
  • Comfortable working independently in a fully remote environment.
  • English level: Fluent
  • All candidates must be currently based in Portugal or Brazil

Nice to Have• Experience with both Azure and AWS.

  • Experience designing and building AI/LLM platforms or agentic architectures.
  • Experience with developer platforms, internal tooling, APIs, distributed systems, or cloud infrastructure.
  • Experience working in fast-paced, technically complex environments.
