Job description

About Us: Solirius Reply delivers technical consultancy and application delivery to our clients in order to solve real world problems and allow our clients to respond to an ever-changing technical landscape. We partner closely with our clients, embedding our consultants into their businesses in order to provide a bespoke service, allowing us to truly understand our clients’ needs.

It is this close collaboration with our clients that has enabled us to grow rapidly in recent years and will drive our ambitious future growth plans. We currently have over 250 consultants working with a variety of key clients from both the public and private sectors such as the Ministry of Justice, Department for Education, FCDOS, UEFA, International Olympic Committee and Mercedes Benz; with plans to increase our client base further in the near future.

We operate as a flat organisation and believe in trusting and supporting our team to operate independently. We pride ourselves on being specialists at what we do, making the most of our consultants' expertise in their fields, to provide a best-in-class service to our clients. All our consultants have the opportunity to work on a range of different projects, providing a broad range of knowledge on which to develop their careers and progress in the direction they choose

About You:

You are a motivated and adaptable professional with a strong analytical mindset and a passion for using technology to solve real-world problems. You enjoy working in collaborative, agile teams and take pride in delivering high-quality solutions that make a tangible impact. With strong communication skills and a consultative approach, you’re comfortable engaging with clients, understanding their needs, and translating them into effective outcomes. You understand and align with Solirius Reply Values.

The Role:

We are looking for experienced Solution Architects to work on our projects with our public sector clients, helping to deliver Solirius’ services to the highest standard.

The role will involve working with multiple business stakeholders, helping them to design business solutions which will then be implemented by the delivery teams.

As a Solution Architect, you will be expected to operate with a high degree of autonomy, using your experience and judgement to resolve complex technical and architectural challenges in alignment with client needs.

Successful candidates will also be expected to take an active role in practice development: developing new services to help with Solirius’ business development - creating and updating new architecture artefacts, liaising with the other Solirius practices to maintain practice profile and contributing to the development of more junior practice members.

In addition to technical leadership, you will play a key role in identifying and shaping new business opportunities, working closely with stakeholders across client organisations to understand strategic objectives and deliver value-driven outcomes.

You must be a strong and confident communicator, capable of influencing both technical and non-technical audiences. You will lead and mentor technical teams, build consensus across diverse stakeholder groups, and foster collaborative, cross-functional working environments.

Your role will require innovative thinking, applying best practices and emerging technologies to solve complex business problems in creative and pragmatic ways.
