Senior Lead Full-Stack Engineer (Java/Spring Boot/React/Cloud) – Full Remote ABOUT THE OPPORTUNITY This is a senior engineering role inside a software house with a startup mindset — small team, real ownership, and a genuine appetite for new technologies. You won't be maintaining legacy systems in silence. You'll be shaping how things are built, contributing to architecture decisions, and working with a team that values critical thinking and proactivity over process compliance. If you've spent 5+ years doing serious Java backend work, you're curious about where AI-assisted development is going, and you want to actually influence the technical direction of what you build — this is worth your attention. At HumanIT (4.4 ⭐ on Glassdoor, 89% recommend), people stay because the work is real and the culture backs it up. Remote-first, autonomous, and built around people who want to grow — not just deliver tickets. 🔗 What it's really like to work here: PROJECT & CONTEXT You'll work within a small, cross-functional engineering team building modern software products across dynamic and innovative projects. The role is firmly backend-focused, but you'll collaborate across the full stack and contribute to architecture discussions that go beyond your immediate feature scope. The team embraces AI code assistance tooling as part of the daily workflow — including OpenCode, Ollama, Qwen3, Claude Code, and similar tools — expecting engineers to use them actively for development, refactoring, testing, documentation, and troubleshooting. This is an environment that rewards autonomy, continuous learning, and technical curiosity.
