Job Description

🌟 The Opportunity

We’re looking for a Senior Software Engineer to step into a leadership role within our engineering team — someone who doesn’t just write code, but shapes how we build, grow, and innovate. You’ll be at the heart of designing scalable systems, mentoring developers, and driving technical excellence across high-impact projects.

This is your chance to lead by example, solve complex challenges, and help define the future of our software architecture — all while working with modern tech and a team that values craftsmanship and collaboration.

🧩 What You’ll Do

• Architect with purpose: Design robust, scalable systems that stand the test of time — think long-term reliability, not just quick wins.
• Lead the team forward: Mentor junior engineers, share best practices, and foster a culture of continuous learning and technical excellence.
• Tackle the tough stuff: Dive into the most complex parts of the codebase, optimize performance, and drive innovation.
• Bridge business & tech: Work closely with stakeholders to turn real-world needs into smart, scalable solutions.
• Improve how we build: Challenge the status quo — refine our tools, processes, and CI/CD pipelines to ship better software, faster.
• Solve under pressure: Be the go-to expert when things go sideways — troubleshoot critical issues and keep systems running smoothly.
  
  
  

🛠️ What You Bring

✅ Must-Haves

• Proven experience (5+ years) in software development with a track record of delivering complex, high-quality systems.
• Strong expertise in:
• Java 11+ and Spring Boot
• Angular 17 (front-end mastery)
• REST API design
• SQL (MySQL is a plus)
• Deep understanding of software architecture, scalability, and maintainability.
• Solid experience with cloud infrastructure, containerization, and CI/CD pipelines.
• Natural leader — great communicator, mentor, and collaborator.
  
  

🌱 Nice-to-Haves

• Experience with Docker, Git/GitLab, MongoDB, or Elasticsearch
• Background in MVC patterns
• Familiarity with GWT (Google Web Toolkit) — bonus points!

💬 Why This Role Matters

You won’t just be another developer on the team — you’ll be a technical compass, guiding projects from concept to production. Your work will directly influence product quality, team growth, and engineering standards.

If you love solving hard problems, lifting others up, and building systems that matter — this is your playground.
