About Us

H2 Cognitive Designs (H2CD) is a health technology company working at the intersection of cognitive science, clinical research, and large-scale digital assessment. We build platforms used to measure cognitive performance across clinical trials, occupational health programmes, and large institutional deployments in the UK and internationally.

Our clients include demanding and security-conscious organisations across healthcare, national institutions, and sectors where the performance and reliability of what we build genuinely matter. Our infrastructure is cloud-native, and our engineering team is distributed, collaborative, highly skilled and highly specialised.

We have a rapidly growing portfolio of significant projects, and this role sits at the heart of how we deliver them.

Monitor software performance and implement optimizations as needed
Respond efficiently to reported software maintenance and defect requests
Maintain accurate version control and documentation of reported issues and remedial actions taken
Implement bug fixes and enhancements promptly

Testing and Quality Assurance

Write and execute unit tests, integration tests, and end-to-end tests
Identify and resolve software defects and security vulnerabilities
Ensure that all code meets industry standards for security and data protection
Apply best practices for test-driven development when appropriate
Maintain test documentation and test coverage

Professional Development

Stay current with industry trends, technologies, and best practices
Participate in team meetings and initiatives to support business growth
Research and evaluate new technologies that could benefit the company
Share knowledge and expertise with team members
Propose innovative solutions to technical challenges

What We Are Looking For

Essential

Bachelor’s degree in Computer Science, Software Engineering, or related field, or equivalent practical experience
Proven experience delivering high-quality full-stack web applications
Experience with Django web framework
Excellent knowledge of Python, HTML, and JavaScript
Strong working knowledge of Git version control
Experience with Docker containerization
Familiarity with database design and management
Ability to work independently and collaboratively in a small team
Strong problem-solving skills and attention to detail
