Description
Work on Technology That Protects What Matters
At SiXworks , we build secure digital solutions that support Defence and National Security missions . Our teams work on complex problems where reliability, security, and speed of innovation matter.
We’re looking for a Software Engineer who enjoys solving difficult technical challenges and wants their work to have real operational impact.
This role requires occasional visits to Herefordshire
What You’ll Do
As a Software Engineer , you’ll help design, build, and deliver secure digital solutions in highly secure environments. You’ll work alongside engineers, architects, and delivery specialists to develop technology that enables faster, safer decision-making for critical operations.
Your work may include:
Collaborate with the development team to design, develop, and maintain software solutions.
Develop reliable applications in Kotlin Jetpack Compose for Android.
Utilise GIT for version control, ensuring efficient code management and collaboration.
Design and implement backend solutions using either Rust, Python, or Go, ensuring robustness and scalability (e.g. writing web APIs)
Utilise Docker for containerisation to streamline deployment processes and ensure consistency across environments.
Implement and maintain CI/CD pipelines to automate software delivery and deployment.
Write clean, efficient, and well-documented code following industry best practices.
Participate in code reviews, providing constructive feedback to team members.
Stay updated with the latest technologies, trends, and best practices in software development.
What We’re Looking For
We value people who take ownership, think critically, and enjoy working as part of a collaborative team tackling complex challenges. You don’t need to tick every box, but we’re particularly interested in people with skills/experience in:
Bachelor's degree in Computer Science, Engineering, or related field.
Strong proficiency in GIT for version control and collaborative development.
Proficiency in Android Kotlin front-end development.
Happy to develop PoC applications where requirements may change rapidly and rework is common.
Familiarity with backend development languages such as Rust, Python, or Go.
Solid understanding of software development principles (MVVM, UDF), Web APIs, standards (e.g. OpenAPI), and data structures.
Experience with Docker for containerisation and deployment.
Knowledge of DevOps processes, including CI/CD pipelines and automated testing frameworks.
Strong communication and collaboration abilities within a team environment.
Ability to adapt to a fast-paced, dynamic work environment and learn new technologies quickly.
Comfortable with developing in a secure environment (on remote developer environments, VMs etc)
Just as important are curiosity, strong problem solving ability, and the motivation to continuously improve how technology is designed and delivered.
