Job description

ADP is hiring a Full Stack .NET based AWS Senior Software Engineer

Being able to work independently with minimal guidance, the ideal candidate will have strong business acumen, broad technical skills, and experience managing enterprise development and integration projects. The successful candidate will have a strong understanding of advanced C#.Net, SQL & NoSQL databases and experience of building cloud native REST APIs and serverless applications.

Technical leadership, including the ability to coach and train other developers and to drive continuous improvement through established agile practices is key to this role. You will be comfortable spending more time supporting others than hands‑on coding yourself. In addition, you will be a champion for quality with recognition for the importance of automated testing, meeting non‑functional requirements, maintaining operational tooling, and enabling continuous delivery. This role requires a deep understanding of both front‑end and back‑end technologies, cloud infrastructure, and a strong commitment to best practices.

• Set the gold standard for the team's output and inspire others to deliver to it by following your example.
• Guide the team to deliver at a predictable cadence without compromising quality or non‑functional concerns.
• Provide strong governance within the team to ensure adherence to the principles as laid out by the system architecture.
• Build good relationships with other functions such as Architecture, Product, other development teams and the wider business to ensure your team is building the right solutions in the right way.
• Ensure outcomes are identified and measured for success.
• Conduct code reviews, enforce coding standards, and ensure the quality and maintainability of the codebase.
• Identify and resolve performance bottlenecks in applications and optimize the use of cloud resources.
• Implement best practices for application security, data protection, and compliance with relevant regulations.
• Maintain growth through awareness of modern technologies, both for yourself and the team.
• Drive improvement individually and collectively, mentoring as the need arises and through dedicated sessions.
• Provide transparency to other parts of the organization on project progress, team maturity and ongoing challenges.
• Speak confidently about the technology used in each product and the associated benefits and drawbacks.
• Liaise regularly with internal onshore and offshore delivery teams including other ADP technology business units.
• Maintain a focus on how the software will deliver value to the end user and how it can be tested, deployed, maintained and operated.
• Ensure the work undertaken by the team is well scoped and clearly defined.
• Maintain awareness and support of ADP policies and procedures.
