Principal Software Engineer

Leeds / Hybrid

High-Growth Technology Consultancy

Market Led Salary

We're working with a rapidly growing technology consultancy that's proving you don't have to sacrifice culture for scale. While the business continues to expand and win major client programmes, it has retained the collaborative, customer-first mindset that made it successful in the first place.

This isn't a consultancy built on body-shopping or endless layers of process. It's a business that prides itself on delivering real outcomes, building trusted client relationships, and creating an environment where talented engineers can do their best work.

They're now looking for a Principal Software Engineer to help lead the next stage of growth. This role is ideally suited to someone who has already built a successful career within consulting, has seen what great looks like across multiple organisations, and is passionate about sharing that experience with others.

You'll be the kind of person who's been there, done it, learned the lessons, and now wants to help shape engineering teams, influence technical strategy, and raise the bar across the business. You'll bring credibility, pragmatism, and leadership, while helping to develop the next generation of engineers and consultants.

What We're Looking For

Essential Experience:

• Proven experience working within a technology consultancy environment
• Strong development experience across at least two of the following:
• Python
• JavaScript
• Node.js
• C#
• Java

Commercial experience with:

• AWS and/or Azure
• Infrastructure as Code (Terraform or equivalent)
• CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, Azure DevOps)
• Agile delivery environments
• Supporting and evolving live products
• Source control using Git
• Relational and/or NoSQL databases

Demonstrable experience of:

• Technical leadership across teams or programmes
• Mentoring, coaching, and developing engineers
• Influencing senior stakeholders and decision-makers
• Driving architectural direction and engineering standards
• Building high-performing teams and engineering cultures
• Balancing short-term delivery with long-term technical strategy

Desirable Experience

• Public sector or healthcare delivery experience
• MongoDB or other NoSQL technologies
• Community involvement through blogs, meetups, speaking engagements, or open-source contributions
• Experience helping consultancies scale engineering capability and maturity

The Opportunity

As a Principal Software Engineer, you'll provide technical leadership across multiple client engagements, helping organisations tackle complex challenges and deliver meaningful outcomes through technology.

You'll be trusted to:

• Lead technical strategy across programmes and delivery teams
• Shape architecture and engineering decisions that stand the test of time
• Mentor, coach, and develop engineers across the organisation
• Drive engineering best practice, quality, and continuous improvement
• Work closely with senior client stakeholders, translating business objectives into technical solutions
• Champion modern engineering and DevOps principles
• Support teams through the full software development lifecycle, from discovery to delivery and beyond
• Share knowledge, challenge thinking, and help build a world-class engineering culture

What's In It For You?

This is a fantastic opportunity to join a consultancy that is growing at pace, investing heavily in its people, and building a reputation for delivering exceptional outcomes without losing sight of what matters most—its people, clients, and culture.

If you're an experienced consultancy engineer who wants to influence at scale, develop others, and help shape the next chapter of a genuinely people-focused consultancy, we'd love to hear from you.
