Are you a technical architect looking for a new opportunity? Now is a fantastic time to continue to build your career in our exciting, creative and world-class software development team. If you want to learn, lead and help others to deliver technological solutions and be part of delivering public service that makes a real difference, HMRC is a great place to do that.
HMRC is replacing legacy applications with SaaS and PaaS cloud services. We need a Senior Technical Architect who will act as the architectural authority for Business Developed Applications (BDApps), defining how we use our technology stack across the estate, including application structure, hosting models, security patterns, integration approaches and lifecycle management. You will guide teams on when Blazor is the right choice and when alternative approaches are more appropriate, making technology decisions based on fitness for purpose rather than novelty.
As a senior member of the multidisciplinary Technical Innovation team, you will work with Product Managers, Software Developers and technology specialists to provide architectural leadership for HMRC’s Business Developed Applications estate. You will oversee around 140 desktop and web applications, ensuring they are efficient, effective and aligned to HMRC’s wider technology strategy.
Your focus is shaping and governing the technical direction of BDApps as they move from legacy solutions to modern SaaS and PaaS services on AWS. You will define and maintain the BDApp Platform, setting clear standards, patterns and guardrails that enable teams to deliver safely and consistently. This includes providing strong direction on web architecture, Blazor based solutions and cloud native use of AWS, with decisions driven by user need, operational reality and value.
You will work closely with delivery teams, business partners and IT colleagues to review designs, challenge proposals and set clear architectural direction. You will support teams running live legacy applications while defining realistic, phased migration paths to AWS hosted web services and SaaS solutions. You will ensure BDApps integrate cleanly with the wider HMRC technology stack and support end to end digital services.
The role focuses on architectural leadership rather than hands on development. You will address issues across the BDApp estate, identify opportunities to simplify and standardise and assess emerging technologies where they add value. You will contribute architectural input to business cases and strategic decisions. You will not be expected to code, but you must be technically credible, comfortable working in ambiguity and able to explain complex technical concepts to non technical audiences.
Candidate profile
We are looking for a Senior Technical Architect who provides clear, pragmatic technical leadership across HMRC’s BDApp estate. You will shape and govern the architecture for around 140 desktop and web applications, balancing the need to run and improve legacy services with a steady transition to modern SaaS, PaaS and AWS hosted web solutions. You are comfortable working at pace in complex environments, able to make sound architectural decisions and explain them clearly to both technical and nontechnical audiences. You focus on service quality, sustainability and user need, selecting technology because it is appropriate to the problem and not because it is new. You work confidently with delivery teams, senior stakeholders and partners to ensure BDApps are efficient, secure and aligned to HMRC strategy.
