The Role

We’re looking for a seasoned and driven Lead Back-End Developer to become a key part of our engineering team at EdgeRed. In this vital role, you’ll be architecting, developing, and guiding the implementation of cutting-edge back-end systems for our diverse clientele. You’ll use your strong background in application architecture and popular Python frameworks like Django, FastAPI, and Flask to create scalable, dependable, secure, and high-performing services. This role offers the exciting opportunity to work on a stimulating mix of projects, including green-field development and enhancing existing client applications, translating client needs into robust, scalable, and secure Python-based solutions. As a lead, you’ll also guide and mentor other developers, promote technical best practices including security, and have a real say in our technology direction.

  • Architecture & Design: Take the lead on designing and architecting solid, scalable, and secure back-end systems, APIs, and microservices, across both new and existing client applications.
  • Develop & Implement: Write clean, efficient, maintainable, and well-tested Python code using frameworks like Django, FastAPI, Flask, and other relevant tools for various client projects.
  • Leading & Mentoring: Provide technical leadership, guidance, and support to the back-end development team, encouraging a culture of technical quality and teamwork.
  • Tech Strategy: Play a key part in shaping our back-end technology strategy, looking into and recommending new tools, technologies, and ways of working relevant to client needs and different project types.
  • Code Quality: Promote and uphold best practices in software development, including secure coding standards, code reviews, automated testing (unit, integration), CI/CD, and good documentation.
  • Teamwork & Client Interaction: Work closely with front-end developers, DevOps engineers, product managers, and potentially client stakeholders, to understand requirements and deliver high-quality solutions.
  • Performance Tuning: Pinpoint bottlenecks, optimise application performance, and make sure our back-end infrastructure is reliable and scalable.
  • Problem Solving: Investigate and sort out complex technical issues in both development and deployed client environments.
  • Solid experience of 7+ years in back-end software development, with substantial Python experience.
  • Proven experience (2+ years) in a technical leadership or application architecture position, ideally including experience designing systems and evolving existing architectures.
  • Extensive hands-on experience with Django, FastAPI, and Flask.
  • Experience with cloud platforms (AWS, Azure, or GCP).
  • Strong skills with other common Python libraries and tools (e.g., SQLAlchemy/Django ORM, Celery, Pytest, Pydantic).
  • A good grasp of software architecture principles, design patterns (like MVC, Microservices, Event-Driven Architecture), and RESTful API design.
  • Good understanding of web application security principles, common vulnerabilities (e.g., OWASP Top 10), and effective mitigation strategies.
  • Experience designing and using relational databases (e.g., PostgreSQL, MySQL) and ideally NoSQL databases (e.g., Redis, MongoDB).
  • Proficient with version control, especially Git.
  • Experience with automated testing frameworks and approaches.
  • Understanding of CI/CD principles and tools.
  • Top-notch problem-solving, analytical, and debugging abilities.
  • Great communication and people skills, with the ability to mentor and lead effectively, and potentially engage with clients.
  • Experience working in a consulting or agency environment, delivering projects for external clients.
  • Experience with containerization (Docker) and orchestration (Kubernetes).
  • Knowledge of asynchronous programming in Python (asyncio).
  • Familiarity with front-end technologies (e.g., React, Vue, Angular) is beneficial.
  • Experience with message queues (e.g., RabbitMQ, Kafka).
  • Understanding of DevOps practices and infrastructure-as-code.
  • Experience with specific security tools or formal security reviews/audits.
