About us
Giant Group is a workforce management business on a mission to make work just work. We support recruitment agencies, enterprise and SME businesses, contractors and workers across payroll, compliant employment solutions, invoice financing, back-office management and workforce technology.
We have been operating for over 30 years, are completely self-funded and are expanding in the USA. A major part of our next stage is becoming increasingly platform-led: using technology, automation and AI to make customer and worker journeys simpler and to allow revenue and service quality to grow faster than headcount.
The impact of your role
You will lead an established engineering team of around 20–25 people across the UK and Pakistan, owning engineering delivery, quality, testing, releases, technical standards, capability and technical debt.
Assess the team objectively, develop its strengths and make proportionate improvements to capability, structure and delivery. Stay close enough to the people and technology to understand the causes of problems and lead practical change.
Our technology estate includes significant established and legacy JavaScript,.NET core and.Net framework, C# and Microsoft SQL based applications. You do not need to code every day or be a database specialist, but you must have enough current technical depth to understand the environment, challenge engineers constructively and make sound technical judgements.
Product owns the customer problem, product vision, priorities, roadmap and outcomes. You will agree realistic delivery commitments jointly with the Head of Product and the business, based on capacity, complexity and dependencies, and be accountable for Engineering’s execution. The Group CTO retains responsibility for Group technology direction, architecture, infrastructure, cyber security and resilience, including approval of major architectural changes. You will lead the engineering team and its delivery within that direction, with authority over day-to-day engineering decisions and delegated accountability across the team.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This is a high-impact senior role with direct access to the CTO, CEO and Head of Product, and real scope to shape how Giant builds software during its next stage of growth.
Key responsibilities

- Work with Product from the beginning to assess options, challenge assumptions constructively and agree scope and sequencing.
- Use AI and automation to improve code understanding, testing, documentation and delivery. Measure the benefits and retain review, security and quality controls.
- Own the engineering budget and capability plan. Improve productivity as the business grows and make well-evidenced investment proposals for people, tools and modernisation, with leadership support.
Essential experience and capabilities
- Significant software-engineering experience followed by substantial engineering leadership responsibility.
- Strong previous experience with JavaScript,.NET core and.Net framework, C# and Microsoft SQL based applications, with sufficient current technical depth to work credibly with senior engineers and technical specialists.
- Proven experience leading and developing a multi-disciplinary engineering organisation of comparable scale and complexity, while staying close enough to the work to know what is really happening.
- Evidence of measurable improvements you personally led in engineering delivery, quality or output.
- Strong people leadership, including hiring, coaching, assessing capability, organisation design and managing difficult performance issues.
- Deep understanding of modern software-development practices, including secure development, testing, QA, change and release management, reliability, observability and production support.
- Pragmatic experience managing technical debt and modernising established or legacy platforms.
- Strong Product partnership, commercial judgement, clear communication and documentation discipline, with the confidence to challenge Product, the CTO and senior engineers constructively.
- Practical fluency with modern AI development tools, with concrete examples of using them to improve engineering productivity, quality or delivery.
- Comfort operating in an entrepreneurial environment, using proportionate processes and adapting when priorities change.
- Ability to work in the UK. Visa sponsorship may be considered for an exceptional candidate.
