About the Role

Reporting to a Software Engineering Manager, the Senior Software Engineer is a major contributor and technical influencer within an engineering team delivering high-quality applications and services used by thousands of customers.

As mkodo evolves, we are looking for more T-shaped engineers: not a ‘jack of all trades’ but individuals with deep expertise in one or more core engineering disciplines, combined with broad experience and adaptability across the wider software stack. While each Senior Software Engineer brings deep mastery in at least one area, they are comfortable collaborating across disciplines and contributing wherever business needs require.

Core areas of depth may include one or more of:

Web / Front-end engineering

Java/AWS backend and distributed systems

React Native

Android (Kotlin)

iOS (Swift)

Successful candidates demonstrate deep expertise in at least one of these areas while maintaining practical experience and willingness to work across others.

This role suits engineers who are highly autonomous, delivery-focused, and capable of owning technical design and execution for complex features and systems, while contributing to team growth and technical direction.

Main Responsibilities

Engineering delivery & technical ownership

Design, build, and deliver high-quality software across mobile, web, and backend systems depending on business needs.

Take complex product or technical problems and break them down into deliverable, well-structured solutions.

Own the technical design and implementation of projects or features of moderate to high complexity.

Write production-quality, well-tested, maintainable code aligned with engineering standards.

Ensure reliability, performance, security, and scalability across systems and platforms.

Drive investigation and resolution of complex technical issues across the stack.

Contribute to and lead technical projects spanning multiple components or services.

Transform and modernise legacy systems where required.

Cross-discipline contribution

Act as a deep expert in your primary discipline while contributing across other platforms or systems.

Collaborate effectively across web, mobile, and backend engineering to deliver cohesive solutions.

Demonstrate adaptability and willingness to work in different parts of the stack as business priorities evolve.

Support shared ownership of system quality and delivery across teams.

Technical leadership & influence

Act as a technology leader within and beyond your immediate team.

Provide clear technical direction and decision-making that supports long-term architectural health.

Identify and drive improvements to engineering practices, tooling, and processes.

Identify, prioritise, and reduce technical debt.

Contribute to architecture discussions and help align teams on technical approaches.

Support drama-free, predictable releases through strong engineering discipline.

Collaboration & delivery excellence

Provide realistic, data-informed estimates and delivery plans.

Break work into clear milestones and deliver predictably.

Collaborate closely with product, design, QA, and stakeholders.

Balance technical, product, and business trade-offs when designing solutions.

Mentor and support other engineers through pairing, reviews, and knowledge sharing.

Contribute to hiring and team growth.

Quality, security & compliance

Implement strong testing, monitoring, and observability practices.

Support security and regulatory compliance (e.g., ISO27001, PCI where applicable).

Adhere to secure coding and operational best practices.

Ensure systems meet reliability, performance, and quality standards.
