Software Engineer (Mid–Senior)

Python Full Stack

A fast-growing, technology-led consumer health & beauty scale-up is looking for a mid-level to senior Software Engineer to join its collaborative engineering team.

The business builds and operates multiple direct-to-consumer brands, supported by a highly bespoke ecommerce platform, internal tooling, and in-house manufacturing systems. Technology sits at the heart of the company, enabling personalised products that make a meaningful difference to customers’ lives.

This is a hybrid role, with regular collaboration time in a London-based office and flexibility to work remotely for part of the week.

The role

You’ll join an agile, cross-functional tech team working across the full stack, partnering closely with Product, Design, and Operations to deliver scalable, high-impact software.

The role has a strong backend focus in Python, with exposure to modern frontend technologies and the opportunity to influence architecture, tooling, and engineering best practices as the platform continues to scale.

This is a great opportunity for an engineer who enjoys ownership, autonomy, and seeing their work have real-world impact.

Responsibilities

• Designing, building, and deploying new features across a multi-brand ecommerce platform
• Writing high-quality, well-tested, maintainable code
• Contributing to architectural decisions and engineering standards
• Collaborating with Product and Design to translate requirements into robust solutions

• Helping scale systems to support rapid business growth

What we’re looking for

Essential experience

• Strong experience with Python and web frameworks such as Flask, Django, or similar
• Experience working with relational databases (MySQL preferred) and ORMs (e.g. SQLAlchemy, Alembic)
• Solid understanding of frontend fundamentals: HTML, CSS, JavaScript
• Strong grasp of software engineering principles:
  • Git/version control
  • Object-oriented programming
  • Testing (unit & integration)
• Comfortable working in a fast-paced, evolving environment

Nice to have

• Experience with TypeScript and React
• Exposure to frontend design systems
• Experience with Docker and cloud platforms (AWS preferred)
• Knowledge of modern web architecture and performance optimisation
• A proactive, pragmatic mindset — someone who takes ownership and gets things done

Why apply

• Join a mission-driven, high-growth tech business
• Work on products used by millions of customers
• Real influence over technical decisions and product direction
• Strong focus on learning, development, and career progression
• Competitive salary (£70k - £90k DOE)
• Equity, and a comprehensive benefits package
