Senior Consultant (.NET Engineering) in Sheffield

We’re looking for brilliant, well-rounded Engineering Consultants who specialise in the .NET ecosystem. At Nimble, you’re more than a developer; you’re a problem-solver and trusted advisor. You are a polyglot engineer at heart - adaptable, pragmatic, and capable of driving end-to-end delivery. You thrive on taking ownership of the entire software lifecycle - seamlessly bridging the gap between business requirements and technical execution to build, deploy, and maintain complete, fit-for-purpose solutions.

What you will do:

• End-to-End Delivery & Analysis: Shape messy backlogs, clarify ambiguous requirements, and drive features from concept to production. You don't just take tickets; you solve business problems.
• Drive Holistic Quality: Think in complete solutions. You evaluate "quality" against the client's reality - balancing Total Cost of Ownership, performance, scalability, maintainability, and pragmatic test automation to ensure sustainable success.
• Engineering in Complex Domains: Deliver robust software across everything from modern cloud-native apps to 20-year-old monoliths. You build the right solution for the client's specific constraints and deadlines.
• AI-Accelerated Engineering: Seamlessly integrate LLMs and AI tooling (Claude, Copilot, Cursor, etc) into your daily workflow to rapid-prototype, accelerate feature delivery, and cut through legacy complexity.
• Consulting & Leadership: Guide clients and small teams through uncertainty. You lead by example, bringing calm and clarity to high-pressure, fast-paced environments.

What you need to bring:

• Consulting Mindset: The ability to build trust, navigate ambiguity, and maintain high performance even when requirements or environments shift.
• Solution Shaping & Cloud Fluency: The ability to design and shape solutions that are right for the problem at hand. You bring proven experience with cloud providers (AWS, Azure, or Google Cloud) and a solid understanding of modern architectural patterns, including Infrastructure as Code (IaC), containerised systems, and serverless architectures.
• Deep Technical Foundations: Strong, proven experience across the .NET ecosystem (C#, modern .NET, legacy frameworks), backed by solid SQL and JavaScript skills.
• Polyglot Mindset: A genuine curiosity and interest in continuous learning. You aren’t dogmatic about tech stacks; you view different languages, older legacy systems, and modern front-end frameworks (like React, Vue, or Angular) as tools to solve problems, and you are eager to pick them up as the project demands.
• AI Tooling Fluency: Hands-on experience using AI coding assistants and LLMs to actively accelerate your development lifecycle.
• Agile Pragmatism: Experience thriving in fast-paced, collaborative spaces. You aren't afraid to question the status quo and organise chaotic workflows.
