Full job description

Overview:

Expleo is seeking Software Engineers to join our growing Belfast team, delivering high-integrity engineering solutions across a range of complex and safety-critical domains. This role is ideally suited to candidates with experience in safety-critical or defence environments, though we also welcome strong software engineers from non-safety-critical backgrounds who are motivated to transition into this space through structured training and mentorship.

Responsibilities:

As a Software Engineer at Expleo, you will work on the design, development, testing, and integration of software systems used in regulated and high-assurance environments. You will contribute to the delivery of robust, secure, and reliable software solutions, often within defence, aerospace, or other safety-critical industries.

While prior safety-critical experience is highly desirable, we provide comprehensive training and support for engineers looking to develop expertise in standards-driven development environments.

Design, implement, and test high-quality software solutions in line with project and regulatory requirements
Work within structured development processes (e.g. requirements traceability, verification & validation)
Collaborate with systems engineers, test engineers, and stakeholders across multidisciplinary teams
Contribute to software design documentation and technical specifications
Participate in code reviews and support continuous improvement of engineering practices
Ensure compliance with relevant safety, security, and quality standards where applicable
Support integration and validation activities in lab or simulated environments

Qualifications:

Candidates without direct safety-critical experience are encouraged to apply. Expleo provides:
- Structured onboarding into safety-critical engineering practices
- Training in relevant industry standards and compliance processes
- Mentorship from experienced engineers within regulated domains
- Opportunities to work on progressively complex and high-assurance systems

Essential skills:

Strong understanding of software engineering principles and lifecycle development
Good problem-solving skills and attention to detail
Ability to work effectively within a team and communicate technical concepts clearly
Bare Metal Programming
Knowledge of embedded systems or real-time software development
HW/SW interfacing
Ability to hit the ground running

Desired skills:

Background in safety-critical, defence, aerospace, automotive, rail, or other regulated industries
Familiarity with standards such as DO-178C, ISO 26262, IEC 61508, or similar

Experience:

Background in safety-critical, defence, aerospace, automotive, rail, or other regulated industries
Familiarity with standards such as DO-178C, ISO 26262, IEC 61508, or similar
Experience with requirements management and traceability tools
Knowledge of embedded systems or real-time software development
Experience with configuration management tools (e.g. Git, SVN)
Experience with requirements management and traceability tools
Experience in software development using languages such as C, C++, Java, or similar
Experience working in structured development environments (Agile, V-Model, or similar)
Experience in software development using languages C, C++
Safety Experience working to develop SIL2 compliant systems
Defence Experience

Benefits:

Collaborative working environment – we stand shoulder to shoulder with our clients and our peers through good times and challenges
We empower all passionate technology loving professionals by allowing them to expand their skills and take part in inspiring projects
Expleo Academy - enables you to acquire and develop the right skills by delivering a suite of accredited training courses
Competitive company benefits such as medical and dental insurance, pension, life assurance, employee wellbeing programme, sports and social events, birthday hampers and much more!

- Offering an interview to disabled people who meet the minimum criteria for the job
- Anticipating and providing reasonable adjustments as required
- Supporting any existing employee who acquires a disability or long term health condition, enabling them to stay in work at least one activity that will make a difference for disabled people
