Our client, a best-in-class globally recognised strategic advisory firm, is seeking an experienced Senior Applications Developer & Data Specialist to join their growing technology team.
This isn't a configure-and-maintain role. Reporting to the Group Head of Business Applications, you'll design, build, integrate, and support the business-critical applications and data platforms used every day by Finance, BI, Marketing, HR, and the wider ICT function. You'll architect complex solutions from scratch, own them end-to-end in production, and play a central part in the firm's drive to bring delivery in-house.
If you're an engineer who wants genuine ownership — the freedom to build properly, the trust to run what you build, and a direct line to the business you're building it for — this is a rare one.
Role Responsibilities
Application development & support
- Own core business applications including Dynamics 365 (Finance, CRM, Marketing), the Microsoft Power Platform (Power Apps, Power Automate, Power BI, Dataverse), Microsoft Forms, and collaboration tools such as SharePoint and Egnyte.
- Manage application environments for stability, performance, and scalability.
Integration & automation
- Architect and implement API integrations and automation workflows across the business — building complex solutions from scratch using C#, Azure, and modern integration patterns.
- Proactively identify and deliver automation and process-optimisation opportunities.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Data & reporting
- Support and enhance the data warehouse / data lake and internal ICT reporting mechanisms.
- Build and maintain Power BI dashboards and data tools.
- Define and lead data quality standards, validation processes, and ownership models across systems.
DevOps & release management
- Own DevOps pipelines and release management using Azure DevOps.
- Champion CI/CD best practice and maintain robust deployment oversight.
Security & governance
- Embed secure development practices in line with ISO standards and the firm's governance framework.
- Support ISO audit activity and ensure compliance across all application work, in close collaboration with the ICT Security team.
Architecture, strategy & stakeholders
- Contribute to application and data architecture decisions and longer-term platform roadmaps.
- Act as technical lead in vendor discussions, third-party assessments, and roadmap reviews.
- Engage business teams directly to turn requirements into scalable, secure solutions.
Essential Skills / Experience
These are the primary differentiators — we need substantial, hands-on delivery, not platform-level familiarity:
- Hands-on C#, .NET and JavaScript development (5+ years) — building complex solutions from scratch
- Azure architecture and services — Web App Services, Azure Automation, Logic Apps
- Azure DevOps ownership — pipelines, release management, CI/CD
- Microsoft Dynamics 365 (FSCM & CE) — 3+ years
- Agile ways of working and adaptability in fast-moving environments
