About Us

Duel is a SaaS company on a mission to make Brand Advocacy the industry standard playbook for building brilliant retail brands. It was founded by world record breaking adventurer and former brand ambassador Paul Archer, alongside viral games developer Naio Tsarouchis, and we exist to show there’s a better way to build businesses, to build a better future, proving that caring for people builds brand, which builds long term and exponential profit returns.

The Duel Brand Advocacy Platform allows enterprise brands to do just that, scaling how they manage their relationships with thousands of advocates, customers, creators and brand ambassadors. We’re proud today that brands such as Abercrombie & Fitch, Charlotte Tilbury, Spanx, Victoria’s Secret and Elemis (to name a few, but not to name some household names that we can’t talk about yet) are doing just that. The Duel team comprises psychologists, brand experts and community builders, combining cutting edge brand expertise, with seasoned SaaS experience.

The Role

You’ll work closely with engineering leadership and cross-functional teams to build new features, enhance our platform, and improve developer experience. We want you to be an integral part of an engineering team that values autonomy, impact, and ownership.

Our technology stack primarily includes Angular (latest version), TypeScript, Node.js, MongoDB, Tailwind CSS, and Elastic Beanstalk (AWS), with an increasing focus on real-time data processing and scalable services. If you enjoy working across front-end, back-end, infrastructure, and everything in between, this role is for you.

We’re looking for someone who will…

• Take end-to-end ownership of new features, from conceptualisation to deployment.

• Design, build, and optimise high-performance applications using Angular, Node.js, and MongoDB.

• Develop and maintain scalable RESTful APIs and scalable services.

• Work on our AWS-based infrastructure and contribute to infrastructure-as-code practices.

• Ensure best practices for security, scalability, and maintainability across the application.

• Actively participate in architecture discussions and technology decisions.

• Work closely with Product, Design, and other Engineers to create intuitive and effective solutions.

• Mentor and support junior engineers, fostering a culture of continuous learning.

• Help optimise database performance, indexing, and query efficiency in MongoDB.

• Contribute to the enhancement of front-end practices, including the adoption of Tailwind CSS for scalable design systems.

• Take care of your own DevOps and security to ensure the stability and security of applications.

• Improve developer experience by automating repetitive tasks and enhancing deployment pipelines.

We’d love to hear from you if you..

• Have 4+ years of experience in a fullstack engineering role, preferably in a SaaS or high-growth startup environment.

• Have the ability to break down complex problems, investigate effectively, and drive solutions.

• Have the ability to “work off your own steam” in an autonomous environment, making independent decisions while keeping teams aligned.

• Work iteratively and collaboratively, preferring to ship quickly and refine based on feedback.

• Value creating scalable systems that allow other teams to move faster and be more self-sufficient.

• Value documentation and knowledge sharing to improve team efficiency.

• You are comfortable navigating uncertainty and helping shape solutions without a rigid roadmap.

Technical Skills
