About the Role

This is a senior engineering consulting role focused on modern application development, with a strong emphasis on system integration. You will work across both business and technical domains; helping to design, build, and improve digital solutions for clients across a range of industries and problem spaces.

We are a growing team, and this role is suited to someone at or approaching the senior level who is comfortable owning technical quality without needing layers of support around them. That means you will sometimes work across the full delivery stack; including tasks that might sit with a junior or intermediate engineer on a larger team. This reflects where we are as a practice, and it comes with real ownership, visibility, and the opportunity to help shape the team as it grows.

You will work closely with stakeholders to understand and shape business requirements, design practical technical solutions, and deliver working software. Our primary stack centres on .NET (Core and Framework) and React, but this is a consulting environment, we select the best tool for the client's problem, and we expect the same mindset from you. Strong transferable skills and sound engineering judgement matter more than deep specialisation in any single framework.

This role suits someone who enjoys variety, can move fluidly between technical design and hands-on development, and is comfortable contributing across the full software development lifecycle. Clear direction will not always be available upfront; the ability to ask the right questions, make sound assumptions, and proactively seek guidance is important.

Core Responsibilities

• Design, build, test, and maintain full-stack solutions across .NET (Core and Framework), React, and JavaScript/TypeScript, with Python used where appropriate
• Lead or contribute to architectural decisions and technology feasibility assessments, producing clear technical specifications from requirements through to system design
• Design and implement integration and middleware layers that connect enterprise systems, ensuring data integrity, auditability, and consistency across the full pipeline
• Deliver well-estimated, well-structured solutions: factoring in security, scalability, and maintainability from the outset
• Engage confidently with both technical and non-technical stakeholders, translating between business requirements and technical solutions
• Support and mentor junior team members as the team grows, contributing to a culture of quality and knowledge sharing
• Participate in code reviews, testing, and CI/CD practices, upholding team standards across the delivery lifecycle
• Provide support and maintenance across existing and new solutions, including participation in security and vulnerability reviews

Technical Standards & Ways of Working

• Apply OWASP standards and SDLC principles as a baseline, not an afterthought
• Bring first-principles thinking to new problem domains; able to decompose unfamiliar requirements into sound technical designs regardless of industry or stack
• Operate as an engineering generalist: equally comfortable writing production code, producing technical documentation, reviewing pull requests, estimating delivery risk, and presenting options to clients
• Manage periods of multiple concurrent client engagements where priorities may shift; maintain quality and communication across all commitments

Advantageous

• Cloud infrastructure experience including Azure (preferred), AWS, or GCP, particularly container orchestration, Entra ID / Azure AD authentication, secrets management, and parameterised CI/CD pipelines
• Practical experience integrating AI capabilities into solutions; working knowledge of API-based AI integration, RAG patterns, or agentic tooling is more valued than theoretical familiarity
• Experience designing and delivering multi-tenant or white-label cloud solutions with per-client resource isolation

What You Bring

You are a strong intermediate engineer ready to make the step up, or an early-career senior who wants real ownership and variety rather than a narrow lane in a large team. You bring:

• Approximately 4–6 years of professional software development experience, with demonstrated growth in technical responsibility
• Solid .NET development experience (Core and/or Framework) and proficiency with React or a comparable modern frontend framework
• Genuine comfort working across the stack; backend, frontend, integration, and infrastructure, without needing to specialise in one
• Strong problem-solving instincts and the communication skills to match: you can articulate a technical approach to a non-technical stakeholder without losing the rigour
• A consulting or client-facing mindset, or strong appetite to develop one. You understand that delivery quality and client relationships are inseparable
• Self-motivation and the ability to manage competing priorities with minimal hand-holding
