Senior Engineer in London

We are Brainlabs, the High-Performance media agency, on a mission to become the world's biggest and best independent media agency. We plan and buy media that delivers profitable and sustained business impact. Brainlabs has always been a culture-first company, with a set of shared principles, philosophies and values documented in The Brainlabs Handbook, which has evolved into The Brainlabs Culture Code. This Culture Code consists of 12 codes that define what it means to be a Brainlabber, focusing on continuous development and creating a proud company culture.

As a Senior Engineer, you will be building tools to enhance the capabilities of our internal client-facing teams. Engineers take ownership of features, working with our product team and directly with internal users to design, develop, and iterate on feedback.

What you do:

• Take ownership of features or small-scale projects, from design to deployment.
• Develop features that enable Brainlabs teams to perform data analysis, planning, and testing for marketing campaigns, implementing end-to-end solutions using Python & Django (backend) and Vue.js (frontend), deployed with Docker on GCP.
• Review code to ensure it is maintainable and well tested, providing thoughtful feedback and sharing best practices.
• Collaborate with teams across the company to design features and iterate on feedback, including people from product, client‐facing account management, sales, and our data teams.
• Mentor and support the growth of junior engineers, with the opportunity for people management in the future.

Who you are:

• Professional experience as a software developer, with good computer science fundamentals (degree or equivalent experience).
• Strong proficiency in Python.
• Knowledge of front‐end frameworks (preferably Vue.js).
• Proven ability to own and deliver features or small‐scale projects independently.
• Collaborative mindset with the ability to explain technical concepts to non‐technical stakeholders and contribute to architectural decisions.

How you succeed:

• Driven by product development, user value, and business impact, not just writing code.
• Collaborate effectively with product managers, internal users, and fellow engineers to deliver user‐focused solutions.
• Continuously improve processes, tools, and workflows to enhance team productivity and code quality.
• Communicate clearly and constructively, whether in code reviews, technical discussions, or stakeholder updates.
• Care about quality, focusing on readable code for other developers and intuitive and well-designed UI for our users.
• Contribute to a positive team culture, supporting others and leading by example, living our culture code every day!
