Job Description

Waracle are looking for a Principal Developer for an exciting new role joining 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.

Role Overview

Are you a strategic thinker who enjoys nurturing talent as much as solving complex technical puzzles?

We are looking for a collaborative Principal Developer to act as a technical North Star across multiple squads. In this role, you'll move beyond just writing code to shaping the very architecture of our digital products, ensuring they are secure, high-performing, and inclusive by design.

This is a Hybrid role, offering the flexibility to balance your professional and personal life, with 2 days a week spent connecting with colleagues in our London office. This role can be permanent or an Inside IR35 contract.

Key Duties and Responsibilities
  • Strategic Leadership: Shape and evolve technical architecture across various large-scale programmes.

  • Trusted Advisor: Build meaningful relationships with client stakeholders, translating complex concepts into clear, actionable strategies.

  • Mentorship & Growth: Actively support the career journeys of Lead and Senior Engineers, fostering a culture of continuous learning and technical excellence.

  • Innovation: Select the tools and frameworks that allow us to scale, while balancing commercial needs with high-quality user experiences.

  • Community Building: Define and evolve our practice standards, contributing your unique insights to Waracle's collective body of knowledge.


What you'll bring to the role:

We value a broad range of perspectives and experiences. If you are a natural problem-solver who thrives on collaboration, we want to hear from you.

  • Technical Artistry: Proven experience shaping and documenting architecture for large-scale programmes.

  • Modern Ecosystems: Strong expertise in scalable technologies, specifically React Native, with some knowledge of Python.

  • Empathy & Influence: The ability to navigate complex organisations and manage diverse stakeholders through clear, supportive communication.

  • Ownership Mindset: A dedication to driving positive outcomes and maintaining high standards of delivery.

  • Leadership: A focus on strategic decision-making and a passion for developing the next generation of technical leaders.

The recruitment process you can expect for this role is an initial call with your dedicated Talent Attraction Partner who will chat with you about Waracle, what you are looking for in a new position, the salary for the role, notice period and benefits (the important stuff!).

After that, you'll be invited to a two-stage interview process where you have an opportunity to find out more about the role and showcase your skills and experience. Your Talent Attraction Partner will guide you through the whole process to your first day with us.

Our Benefits

We believe in supporting our team holistically, ensuring you have the tools to thrive inside and outside of work:

  • Rest & Recharge: 35 days of holiday (27 days annual leave plus 8 bank holidays).
  • Financial Security: Company-matched 5% pension and a Death in Service benefit (2x salary).
  • Health & Wellness: Medicash Health plans, Employee Assistance Programme, and Group Sickness Cover.
  • Flexible Working: Hybrid-first approach with a home office setup budget.
  • Learning & Growth: Access to Udemy Business and a dedicated L&D budget for your continuous development.
  • Family First: Enhanced parental leave policies, including specific support for fertility journeys.
  • Community: Monthly office lunches, regular meet-ups, and the Spirit of Waracle initiative for local charitable impact.

We are an equal opportunities employer and welcome applications from all suitably qualified persons regardless of their race, gender, disability, religion/belief, sexual orientation or age.
