Job Title
We are seeking a highly experienced and competent Senior Developer with expertise in C#/.NET and a strong background in stakeholder engagement to work within a collaborative, cross-functional team.

As a Senior Developer, you will be able to articulate and advocate for architectural patterns, engineering and testing principles to drive our product forward as we scale.
Role Responsibilities
- Understand business requirements and translate them into user-facing features using.NET (C#) and Python.
- Work closely with other members of the Individual Retirement Solutions team (including business stakeholders) to understand the logic and rationale behind the Retirement Pathway.
- Participate and contribute to the go-to-market strategy for this new business line.
- Own features and releases to ensure they are delivered as quickly as possible without compromising on quality.
- Take a security first approach to development to protect sensitive data and Insight’s reputation.
- Conduct code reviews and provide constructive feedback to peers.
- Inform and improve our testing strategy, working with other developers and QAs to evolve our test suites (Unit, Integration and Automation tests).
- Contribute to the continuous improvement of the team by enhancing our delivery process and coding efficiency.
- Work closely with Insight’s existing technology organization to ensure corporate standards and regulatory requirements are met.
- Stay up-to-date with the latest industry trends and technologies.
- Participate in and, where appropriate, lead meetings with business stakeholders.
