About Methods

Methods is a £100M+ IT Services Consultancy who has partnered with a range of central government departments and agencies to transform the way the public sector operates in the UK. Established over 30 years ago and UK-based, we apply our skills in transformation, delivery, and collaboration from across the Methods Group, to create end-to-end business and technical solutions that are people-centred, safe, and designed for the future.

Our human touch sets us apart from other consultancies, system integrators and software houses - with people, technology, and data at the heart of who we are, we believe in creating value and sustainability through everything we do for our clients, staff, communities, and the planet.

We support our clients in the success of their projects while working collaboratively to share skill sets and solve problems. At Methods we have fun while working hard; we are not afraid of making mistakes and learning from them.

Predominantly focused on the public‑sector, Methods is now building a significant private sector client portfolio.

Methods was acquired by the Alten Group in early 2022. Alten is a global engineering firm with approximately 57,000 employees specializing in engineering and IT services.

Security Clearance

BPSS (Required) / SC (Preferable)

Overview

We are looking for a Senior .NET Developer with a deep mastery of the Microsoft Azure ecosystem to lead the delivery of critical digital services for the public sector. This isn't just about writing code; it’s about shaping the technical direction of high-impact programmes that serve millions of citizens.

As a Senior member of the team, you will act as a bridge between complex architectural requirements and high-quality execution, ensuring that our solutions are secure, scalable, and aligned with Government Design Service (GDS) standards.

Key Responsibilities

• Technical Leadership: Lead the design, evolution, and maintenance of robust applications using .NET 8/Core and C#, setting the gold standard for code quality within the team.
• Architectural Oversight: Drive the implementation of cloud‑native architectures on Azure, making high‑level decisions on service selection (Functions, Service Bus, CosmosDB, etc.) to ensure cost‑effectiveness and performance.
• Security & Compliance: Take ownership of secure coding practices. You will ensure all solutions meet rigorous government security classifications and accessibility standards (WCAG).
• Mentorship: Act as a technical mentor to mid‑level and junior developers, conducting code reviews and fostering a culture of continuous learning and engineering excellence.
• Stakeholder Collaboration: Work closely with Product Owners, Delivery Managers, and Architects to translate complex policy requirements into technical roadmaps.
• DevOps Culture: Champion a "you build it, you run it" mindset by refining CI/CD pipelines and improving automated testing strategies.

Essential Skills & Experience

• Expert .NET Mastery: Extensive experience with C# and .NET Core/6+, including deep knowledge of dependency injection, middleware, and asynchronous programming.
• Azure Expert: Proven track record of architecting and deploying complex solutions using Azure App Services, Logic Apps, Key Vault, and Azure SQL.
• Modern Patterns: Expert knowledge of Microservices, Event‑Driven Architecture, and RESTful API design.
• Data Integrity: Strong experience with both SQL Server and NoSQL environments, including performance tuning and data modeling.
• Public Sector Fluency: Direct experience working within GDS frameworks or similarly regulated environments (e.g., Health, Defense, or Finance).
• Engineering Rigor: Experience leading CI/CD transformations using Azure DevOps or GitHub Actions, emphasizing Infrastructure as Code (Bicep/Terraform).

Desirable Attributes

• Containerization: Hands‑on experience with AKS (Azure Kubernetes Service) or Docker for orchestrating complex deployments.
• Frontend Savvy: Experience with modern frameworks like Angular or React to support full‑stack initiatives.
• Certifications: Microsoft Certified: Azure Solutions Architect Expert or Azure Developer Associate.
• Active SC Clearance: While BPSS is required, an existing SC clearance is a significant advantage.

What We Look For in a Senior

We need more than a coder; we need a problem solver who is comfortable with ambiguity. You should be able to explain the "why" behind a technical choice to a non‑technical stakeholder and be willing to challenge the status quo to deliver better outcomes for the public.

By joining us you can expect:

• Autonomy to develop and grow your skills and experience
• Be part of exciting project work that is making a difference in society
• Strong, inspiring and thought‑provoking leadership
• A supportive and collaborative environment.

As well as this, we offer:

• Development access to LinkedIn Learning, a management development programme and training
• Wellness 24/7 Confidential employee assistance programme
• Social – Breakfast Tuesdays, Thirsty Thursdays and Pizza on the last Thursday of each month as well as commitment to charitable causes
• Time off 25 days a year
• Pension Salary Exchange Scheme with 4% employer contribution and 5% employee contribution
• Discretionary Company Bonus based on company and individual performance
• Life Assurance of 4 times base salary
• Private Medical Insurance which is non‑contributory (spouse and dependants included)
• Worldwide Travel Insurance which is non‑contributory (spouse and dependants included)
