Senior Software Engineer | Application Platform | Python | £75,000 - £85,000
Edinburgh / Remote
Are you a Senior Software Engineer who wants to shape a platform, not just implement against a defined design?
We’re looking for a Senior Application / Platform Engineer to join a small, senior team building and evolving a complex, data-driven technology platform.
This is a hands-on senior role for someone who can confidently contribute to backend architecture, system design, and technical direction — not just delivery.
What you’ll be doing:
- Designing and building backend services, APIs, and platform capabilities
- Shaping backend architecture, service boundaries, and system design
- Contributing to ingestion pipelines, data workflows, and scalable processing patterns
- Making pragmatic production trade-offs around performance, reliability, and maintainability
- Designing application patterns around tenancy, permissions, and authentication
- Reviewing code and helping define engineering and AI-assisted development standards
- Working closely with product, data, and infrastructure teams
What we’re looking for:
- Strong experience as a Senior Software Engineer in a product-led, SaaS, or platform environment
- Expert Python development experience
- Strong backend API design (FastAPI or similar)
- PostgreSQL, SQLAlchemy, and solid data modelling experience
- Experience designing scalable, production-grade systems
- Understanding of service-oriented architecture and system design principles
- Cloud experience (ideally AWS), plus Docker and CI/CD
- Strong technical judgement and ability to influence architecture decisions
Nice to have:
- Experience with data-heavy or integration-heavy platforms
- Next.js / TypeScript exposure
- Experience with AI-assisted development workflows
Tech stack:
Python | FastAPI | PostgreSQL | SQLAlchemy | AWS | Docker | Next.js | TypeScript
Why this role:
- Join a small, senior engineering team with real technical ownership
- Influence architecture and shape how the platform evolves
- Work on complex engineering problems with autonomy and trust
- Opportunity to grow into technical ownership of a core domain
- Remote-first with regular team meet-ups
Salary: £75,000 - £85,000
If you’re a Senior Engineer who wants to shape systems, not just build tickets, we’d love to hear from you.
