FryerMiles are delighted to be working exclusively with an early AI startup in their quest to recruit a Senior Backend Engineer (Python), to assist in a long term, well backed scale up. Our client is seeking an experienced Backend Engineer, a sound professional and subject matter expert who has been involved in scale ups previously. This is not a role for someone looking for a short-term stint, we’re seeking a Backend Engineer who is in this for the long run, to be fully involved in the company’s plans and grow with them.

As the Senior Backend Engineer, you will lead the backend development using Python (FastAPI) and managing cloud infrastructure. You will work closely with the CTO and Frontend Lead to design scalable, high-performance systems that power personalised AI-driven learning experiences. This role is ideal for someone with deep expertise in building and operating production-grade systems, who is ready to take full ownership of backend architecture.

Key Responsibilities:

  1. Lead the design, development, and optimisation of the Python FastAPI backend.
  2. Architect and maintain scalable APIs, database models, and AI-driven integrations.
  3. Oversee cloud infrastructure (Azure preferred) to ensure reliability and performance.
  4. Collaborate with leadership on enhancing AI capabilities (including LLMOps) in the backend.
  5. Implement best practices in code quality, testing, and documentation.
  6. Mentor and support other engineers, fostering a strong engineering culture.

Essential Skills & Experience:

  1. Backend Development Expertise
  2. Extensive experience developing, deploying, and managing large-scale backend services.
  3. Proficiency in Python (FastAPI preferred).
  4. Cloud Infrastructure & Scalability
  5. Hands-on experience with cloud platforms (Azure, AWS, or GCP) for deployment and scaling.
  6. Software Architecture & Performance Optimisation
  7. Strong knowledge of database design (SQL), caching strategies, and asynchronous processing.
  8. Experience making architectural decisions for scalable, high-performance systems.
  9. Proactive & Independent Approach
  10. Ability to take ownership of backend development and drive projects autonomously.
  11. Comfortable in a fast-paced startup environment, solving complex technical challenges.

Desirable Skills:

  1. DevOps & CI/CD: Familiarity with pipelines, monitoring tools (OpenTelemetry, Azure Monitor, Prometheus).
  2. Security & Compliance: Understanding of best practices around data privacy and application security.
  3. AI & Machine Learning: Exposure to AI/ML workflows, particularly in LLMOps.
  4. Startup Experience: Prior experience in a high-growth startup environment.
