The Role
As a Senior Software Engineer, you'll build the products our customers rely on every day to make multi-million dollar media
decisions. You'll work across the full stack - from crafting responsive, intuitive frontend experiences through to designing and
scaling the backend microservices that power them - and, given the seniority of this role, you'll also help shape system design
and infrastructure decisions as we scale.
You'll work alongside engineers, product managers, and AI agents as part of our AI-first operating model, where lean,
high-autonomy teams ship fast and learn faster. This is a hands-on engineering role for someone who's comfortable owning a feature
end-to-end - from initial design through to production - and who wants to grow their craft in a fast-moving, ambitious
environment.
Where you'll focus
- Frontend development using modern JavaScript frameworks (React.js or Next.js)
- Backend development using Python-based microservices
- System design and infrastructure, contributing to architectural decisions as we scale
- End-to-end feature ownership across the stack
- (Nice-to-have) Exposure to Data Science / Data Engineering workflows
Key Responsibilities
- Design, build, and maintain full stack features - from frontend UI/UX through to backend services and APIs in Python.
- Contribute to system design and infrastructure decisions, helping evolve our technical foundations as we scale.
- Get involved across the full Software Development Lifecycle, from initial planning and design through execution, release, and
monitoring in production.
- Write clean, well-tested, maintainable code, and champion good engineering practices across the team.
- Collaborate closely with product managers, designers, and fellow engineers to translate requirements into working software.
- Build and consume APIs (REST/GraphQL) that connect frontend experiences to backend services.
- Work with AI agents as part of our AI-first operating model, using clear specifications to shape high- quality, AI-assisted
engineering work.
- Take ownership of the quality, performance, and reliability of the features you ship.
- Participate in code reviews, giving and receiving candid, constructive feedback.
- Stay curious about new tools and technologies, including opportunities to explore Data Science / Data Engineering problems as
they arise.
What are we looking for? We hire for how you think and how you ship. You should apply if you:
- Have around 5+ years of professional experience as a full stack / senior software engineer, with a balanced skill set across
frontend, backend, and infrastructure.
- Have strong, hands-on experience with front-end technologies such as React.js or Next.js, and solid backend experience building
and maintaining Python-based microservices.
- Are comfortable contributing to system design and infrastructure decisions, reflecting the seniority of this role.
- Are comfortable working across the full stack and can move fluidly between frontend, backend, and infrastructure concerns.
- Have solid experience working in an agile environment and know how to embed quality into fast-moving teams.
- Bring exceptional attention to detail and a genuine ownership mindset over what you build.
- Are enthusiastic about new technologies, with the ability to adapt and learn quickly - we're open to candidates with strong
experience in other modern languages/frameworks if the core skill set and seniority are a strong match.
- Have an awareness of spec-driven AI development and how clear specifications shape the quality of AI- assisted engineering work.
- Have the confidence and initiative to evolve ideas and pull pieces of work together into meaningful change.
- Have an active interest in self-learning and growing your craft.
- Nice-to-have: exposure to Data Science / Data Engineering (not core to the role, but a strong plus).
You don't have to tick every box. If you're a strong engineer who's hungry to step up, we'd still like to hear
from you.
