Job Description

Waracle are looking for a Principal Developer to join our world-class digital technology consultancy and home to a diverse, smart, curious, and ambitious community of specialists in technology-driven transformation. We work with ambitious clients to help them solve their biggest business and customer challenges. We help our clients to innovate and create intelligent digital products and services. We thrive on complex challenges and deliver business-critical IT transformation projects, moving seamlessly from strategy, design, and delivery to operations.

This is a Hybrid role working from our London office 2 days a week.

Shape the Future of Digital Innovation

As a Principal Developer, you will act as a strategic technical leader, guiding and shaping robust architectures, data strategies, and cloud-native environments across multiple squads and collaborative programmes. In this role, you will champion technical excellence, making thoughtful choices that balance cost, security, performance, and user experience to help Waracle scale and deliver high-performance, world-class products. If you are a collaborative leader who thrives on mentoring talent, fostering inclusive engineering communities, and navigating complex technical landscapes with empathy and pragmatism, we would love to welcome you to our team.

Duties of This Role

Reporting to the Head of Engineering, your role will cover:

  • Solving Complex Technical Challenges: Partner closely with client technical and business stakeholders at all levels, gaining a deep understanding of their technology estates to advise on impactful, world-class digital solutions.
  • Technical Excellence & Delivery: Shape architectures across multiple squads; select tools and frameworks to scale across clients while optimising for cost, security, performance, and scalability.
  • Collaboration & Stakeholder Management: Act as a trusted advisor to clients on technical strategy and roadmaps, translating complex technical concepts into clear, accessible communication for senior stakeholders.
  • Leadership & Community Cultivation: Mentor Lead and Senior Engineers, foster and grow our engineering community of practice, and ensure cross-team alignment on technical standards.
  • Culture & Knowledge Sharing: Define and evolve Waracle’s technical standards while contributing to our shared body of knowledge through lessons learned, thought leadership, and good practices.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

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.

Research shows that underrepresented groups tend to only apply for roles that they believe they meet 100% of the criteria for. At Waracle, we want to buck that trend! We hire for passion, potential, and mindset as much as credentials. If you think you'd be incredible in the role, then apply - even if you don't think you tick every box.

What you'll bring

  • Architectural Leadership: Proven experience designing, documenting, and scaling complex back-end architectures, distributed systems, microservices, and database designs (SQL and other technologies) within cloud-native environments—particularly Azure (with a focus on API management, maintenance, and scaling).
  • Technical Direction & Delivery Ownership: Strong leadership capability to set clear technical direction, maintain a dedicated ownership mindset, and foster high-standard outcomes across complex enterprise projects.
  • Consultative Communication: Excellent communication and influencing skills, with a demonstrated ability to navigate complex client organisations, support diverse stakeholders, and pragmatically balance commercial constraints with high technical standards.
  • Team Mentorship & Growth: A proven track record of mentoring, developing, and aligning senior engineers and technical leaders to foster a collaborative culture of continuous learning and psychological safety.
  • Modern SDLC Innovation: A pragmatic, forward-thinking approach with a strong interest and enthusiasm for applying AI across the Software Development Life Cycle to enhance engineering practices and advise clients on effective adoption.
