At Skillko HSI, we’re on a mission to simplify training, compliance, and workforce management for businesses across regulated industries. Our platform helps organisations streamline their operations, keep teams safe and certified, and stay ahead of compliance requirements with ease.

As we continue to scale, we’re looking for a Senior Software Engineer to play a pivotal role in the future of our platform—shaping architecture, improving performance, and leading innovation.

You’ll be a key technical voice in our product and engineering team. You’ll be hands-on with code, lead architectural conversations, mentor engineers, and help drive the future of our platform.

You will:

• Assist Principal Engineer in the definition and implementation of scalable, maintainable software architecture

• Provide technical mentorship and guidance to other engineers
• Tackle complex challenges—whether technical or process-oriented—and help deliver smart, pragmatic solutions
• Investigate and resolve production issues with urgency and care
• Collaborate closely with product managers, designers, and DevOps to ship features that deliver real impact
• Champion best practices in testing, documentation, and secure coding
• Keep an eye on the bigger picture—suggesting improvements to tools, processes, or systems where needed

• Backend: Java, Spring Boot, Hibernate
• Frontend: AngularJS
• Database: PostgreSQL (AWS RDS)

• Other: RESTful APIs, automated testing frameworks

• 6+ years of professional software engineering experience
• Strong Java & Spring Boot expertise
• Experience designing and maintaining REST APIs and backend systems
• Hands-on work with Hibernate, PostgreSQL (or similar relational DBs)
• Cloud experience, ideally with AWS and associated tools
• Familiarity with CI/CD pipelines, Git, and test automation
• Solid front-end experience, preferably with AngularJS
• A strong understanding of secure coding principles and application-level security
• Agile team experience with a collaborative mindset
• Excellent communication skills—able to work with both technical and non-technical stakeholders

Nices-to-Have

• Master’s degree in Computer Science, Software Engineering, or related field
• Experience in the compliance, training, or workforce management space
• Familiarity with performance tuning and monitoring production systems
• AWS certifications or similar industry credentials

• Remote-friendly working culture with flexible hours
• Impactful work—you’ll help shape core platform components used by thousands
• Technical ownership—we trust our engineers to make decisions and drive improvements
• Tight-knit, supportive team that values curiosity, learning, and great code
• Room for growth, development, and continued career progression
