Staff Java Engineer

Summary

At Remote Crew, we're partnering with a global sleep health company looking for a Lead Software Engineer to join its growing Porto based engineering team. You'll split your time between shaping technical architecture and writing production code inside a Scrum team. This is an individual contributor role for someone who wants real influence over how products get built, not just a seat in design meetings.

Salary: up to €80k / year

Location: Porto, Portugal.

What You'll Do

• Turn Product Requirements Documents into clear Technical Design Documents
• Define architecture, assess feasibility, and estimate effort for new features
• Design scalable, secure microservices running on AWS
• Embed inside one of four Scrum teams as an active developer
• Write production code in Java and Kotlin, with occasional Angular work
• Help your team break architecture plans into user stories and sprint tasks
• Review code and mentor developers to raise the technical bar
• Partner directly with Product Managers to evaluate trade offs before building
• Work with relational (PostgreSQL) and NoSQL (MongoDB) databases
• Support the team's move away from legacy MongoDB toward PostgreSQL

What We're Looking For

• Strong hands on experience building scalable microservices in Java
• Comfort learning Kotlin on the job if you haven't used it yet
• Proven experience with distributed systems and service boundary decisions
• Working knowledge of PostgreSQL and MongoDB
• A track record of writing technical design documents or RFCs
• Experience working in a Scrum or Agile environment
• Ability to explain technical trade offs to non technical stakeholders
• Comfort mentoring developers through code review
• Some exposure to frontend frameworks, ideally Angular
• You must live within about an hour of Porto

Nice to Have

• Experience with AWS and Kubernetes
• CI/CD pipeline experience
• Background in healthcare tech, regulated environments, or SaaS
• Familiarity with sleep diagnostics or medical devices

Why Work With Us

• Your work directly improves how millions of people sleep and live
• The company is growing fast, around 80% in sales this year, creating new architecture and leadership roles regularly
• No mandatory office days. Fully remote, with the team coming together only occasionally
• You'll split your time evenly between architecture and hands on coding, not just handing off designs to others
• Clear career paths are being built for both individual contributors and managers

If this sounds like your next move, we'd love to hear from you.
