Description
At the moment the company is looking for a Senior/Staff Backend Software Engineer who will take ownership of their core platform and AI Agents backend.
Tasks:
- Design and implement scalable backend services and tools for building and running AI Agents for multiple clients.
- Re‑architect and refactor existing backend services and internal tooling so they can scale from ~10 to 30+ customers.
- Extend and improve the workflow orchestration engine (Temporal) to automate complex operational workflows for content moderation, fraud detection, appeals and payments.
- Define and promote modern design patterns, coding standards and architectural best practices for the backend platform.
- Act as the software “glue” between Machine Learning / MLOps and Platform Engineering teams, integrating models and infrastructure into a coherent product.
- Collaborate closely with product and engineering stakeholders to understand client needs and translate them into technical solutions.
- Write robust, maintainable and well‑tested backend code in Python (and occasionally Go).
- Participate in code reviews, knowledge sharing and continuous improvement of the engineering culture.
Must-have:
- At least 4–5 years of experience as a Backend / Software Engineer.
- Strong hands‑on experience with Python (Go is a plus).
- Solid experience building and operating containerised microservices on Kubernetes.
- Understanding of event‑driven architectures and distributed backend systems.
- Experience working with cloud platforms and a DevOps mindset (infrastructure, monitoring, deployment).
- Basic understanding of machine learning principles and experience integrating with ML‑driven systems or data pipelines.
- Familiarity with AI‑assisted development tools (e.g. Cursor, Claude Code or similar).
- Good spoken and written English.
Nice-to-have:
- Experience with workflow orchestration systems (preferably Temporal).
- Background in early‑stage startups or fast‑growing product companies.
- Exposure to Data Engineering, MLOps and/or Platform Engineering.
- Experience with AWS and event‑driven messaging systems.
Benefits:
- Full‑time, remote‑first role (UK or Europe within ~2–3 hours of London time).
- Competitive salary in the UK market with localization for other countries, plus equity.
- Flexible working hours and location.
- Generous paid vacation, sick leave and parental leave.
- Annual budget for professional development and separate budget for health and wellness.
- Three team offsites per year to London or other locations in Europe.
Interview process:
- Intro call with Toughbyte.
- Interview with VP Engineering.
- Take‑home coding assignment in Python or Go (focus on design and best practices).
- Technical interview based on the assignment: discussion of the solution and a live system design session.
