Job description

Senior Software Engineer C++ (Fixed Term Contract)

Within your role as Senior Software Engineer C++ no two days will look the same; with a variety of projects there’s always something new to learn. You will be joining an already established and talented team, which is currently 150 strong and comprised of Apprentice Engineers through to Solution Architects. You will be provided a clear, individual career path with full training, support and mentorship as required to ensure you are reaching your full potential.

You will be involved in a variety of projects within the Software Engineering team such as regular stand ups, fixing bugs, project, and design, and supporting junior members of the team. Additionally, you will also be part of sprint reviews and demos, product release cycles and reports, to name a few of your responsibilities.

At Microlise we know the importance of a good work/life balance, so offer flexible working opportunities with a low overtime culture; there’s a reason our average length of service is 7+ years! If you are looking for a new challenge and have a strong technical background then we want to hear from you!

As a 12-month fixed-term contract, this role offers the opportunity to make a significant impact on key business-critical projects while working with modern technologies and a highly collaborative engineering team.

Ways of Working:

• Monthly: Contribute to stakeholder demonstrations and product reviews, support the product release cycle, generate technical reports, participate in mobile development activities, and provide engineering input across ongoing projects.
• Fortnightly: Take part in planning sessions, retrospectives, sprint reviews, and team demos, helping to shape delivery priorities and drive continuous improvement.
• Weekly: Engage in public code reviews, engineering dojos, and refinement sessions to enhance code quality, shared understanding, and team capability.
• Daily: Participate in stand‑ups, perform unit testing, submit and review pull requests, conduct code reviews, resolve defects, reduce technical debt, monitor system performance, contribute to design work, and collaborate through katas and pair programming.

What we’re looking for:

• A degree in Computer Science or a closely related technical discipline.
• A strong understanding of fundamental computer science principles and be able to apply them effectively to real-world engineering challenges.
• Demonstrable hands‑on experience working as a Senior Software Engineer, including responsibility for delivering high quality, maintainable software in a commercial environment.
• Significant industry experience with modern C++ (such as C++11 and later), including practical knowledge of memory management, templates, concurrency, and the standard library.
• Experience with C# and the .NET ecosystem is highly advantageous, particularly in scenarios involving cross language integration or tooling. Proven capability to work effectively within an established software development lifecycle, including code reviews, design discussions, and collaborative delivery.
• Strong understanding of object‑oriented programming concepts including encapsulation, inheritance, polymorphism, and abstraction. This should extend to a clear understanding of SOLID principles and the ability to apply them to create robust and extensible software designs.
• Proficiency in SQL, specifically using Microsoft SQL Server, with the ability to write efficient queries, analyse execution plans, and collaborate with database specialists where necessary.
• Experience in implementing and maintaining unit tests across multiple layers of an application, including user interface, back‑end services, and database components.
• Working knowledge of widely used software design patterns, optimisation techniques, performance profiling, and implementation strategies for high throughput or low latency systems.
• Experience mentoring and coaching engineers at various stages of their career development. This includes providing technical guidance, assisting with setting development goals, and supporting colleagues in improving their engineering practices. Ability to contribute positively to team culture, encouraging knowledge sharing, continuous improvement, and collaborative problem solving.
• Enthusiastic, initiative‑taking, and enthusiastic about technology, with a strong desire for continuous learning and professional growth.
• Motivated to succeed, with a commitment to delivering exacting standards of quality and contributing to a positive and productive engineering environment.
