senior software developer.

Our client, a prominent player in the insurance and wealth management sector, is seeking a Senior Software Developer to join a highly collaborative, diverse, and close-knit Shared Services team. Driven by internal promotion, maternity leave, and a major modernization pipeline, this role offers the opportunity to make a tangible impact.

You will split your focus between a critical PowerShell-heavy data movement project (approx. 50–60%) and broader web modernization initiatives. This role is ideal for a senior developer who is passionate about remaining technically hands-on while acting as a mentor to junior developers, co-ops, and offshore resources.

Great Work-Life Balance: Standard 37.5-hour work week, 9–5 hours, with no regular on-call or after-hours support required.

Positive Culture: Work in a highly diverse, supportive team environment with a "mini-family" atmosphere and a strong focus on inclusion and Women in Technology initiatives.

Streamlined Interview Process: A single-stage, collaborative conversation (behavioral and technical discussion) with no live coding or formal assessments.

Responsibilities
Development & Migration: Design, develop, test, and maintain internal applications. Actively participate in modernizing legacy assets (MS Access, on-premises applications, and mainframes) into AWS and Azure cloud environments.

Scripting & Tooling: Lead a high-priority, PowerShell-heavy project ensuring smooth automated processes and file transfers.

Mentorship & Leadership: Provide technical guidance, code reviews, and mentorship to junior developers and co-ops, while acting as an escalation point/advisor for an offshore delivery team.

Production Support: Provide application monitoring, tuning, and troubleshooting. Participate in a volunteer-based, flexible rotation for occasional Friday evening deployments (with time-off-in-lieu provided).

Stakeholder Collaboration: Translate complex technical concepts clearly to non-technical stakeholders, business analysts, and leadership.

- Scripting Mastery: Deep, production-level proficiency with PowerShell scripting.

- Legacy Modernization: Proven experience migrating legacy architectures (e.g., MS Access, VBA, or mainframe environments) to modern cloud/web solutions.

- Cloud & Databases: Hands-on exposure to Azure and/or AWS cloud environments. Strong working knowledge of relational databases (MS SQL, DB2, Entity Framework).

- Dev Tools: Familiarity with Git-based version control (GitLab, SVN) and collaboration tools (Jira, Confluence).
