Senior Python Backend Engineer

Python • Microservices • AI/ML • Cloud & DevOps • Tech Leadership

WeyBee Solutions is looking for a Senior Python Backend Engineer to join our core team as a Tech Lead. You will own the design, implementation, and delivery of scalable backend services and AI-driven platforms that power our products. Beyond writing excellent code, you will set architectural standards, mentor engineers, and directly shape our technical roadmap. This is a high-impact, high-ownership role for an engineer who thrives at the intersection of backend systems and intelligent applications.

• Lead end-to-end backend development — from requirements and architecture to deployment and monitoring.
• Design and build scalable microservices and RESTful / GraphQL APIs that serve critical business and product functions.
• Develop and maintain data processing pipelines, integrating ML/AI algorithms into production systems.
• Own CI/CD pipelines and deployment workflows; ensure reliable, repeatable releases across environments.
• Collaborate closely with AI/ML teams, product managers, and designers to deliver cohesive, high-quality features.
• Define and enforce coding standards, conduct code reviews, and champion software engineering best practices.
• Analyze and optimize system performance, scalability, and stability; identify and resolve bottlenecks proactively.
• Evaluate and introduce new technologies to continuously improve infrastructure and engineering practices.
• Help identify, interview, and onboard strong engineering talent; mentor junior and mid-level engineers.
• Maintain clear technical documentation including architecture decisions, API contracts, and runbooks.

Experience

• 5+ years of professional software development experience.
• Proven track record of delivering production-grade systems in a SaaS or product-focused environment.
• Experience acting as a Tech Lead or senior contributor driving architecture decisions.
• Experience with microservices architecture and distributed systems.
• Experience designing and building production-grade APIs (REST/GraphQL).

Technical Skills

• Proficiency in Python (must-have) — strong command of modern Python patterns, async programming, and performance optimisation.
• Experience with at least one major Python web framework: Django / Django ORM, Flask, or FastAPI.
• Strong understanding of relational and document-based data modeling; hands-on experience with PostgreSQL, MySQL, or MongoDB.
• Deep understanding of multithreading, concurrency, and message queue environments (Kafka, RabbitMQ, Celery, etc.).
• Familiarity with Linux-based development and production environments.
• Solid understanding of software engineering best practices: unit testing, TDD, code reviews, design documentation, modular architecture.
• Strong command of Git, branching strategies, and collaborative development workflows.

Education

• Bachelor's degree in Computer Science, Engineering, Mathematics, or equivalent practical experience.

AI / ML & Computer Vision

• Understanding of Deep Learning concepts and AI/ML algorithm integration into backend systems.
• Experience with image or video processing pipelines (OpenCV, PIL, FFmpeg, or similar).
• Familiarity with ML frameworks such as TensorFlow, PyTorch, or ONNX Runtime.

DevOps & Cloud

• Hands-on experience with CI/CD pipelines and automated deployment workflows (GitHub Actions, GitLab CI, Jenkins, or similar).
• Hands-on experience with Docker and container orchestration (Docker Compose, Kubernetes).
• Experience with cloud infrastructure — AWS preferred (EC2, RDS, S3, Lambda, ECS); GCP or Azure also considered.
• Experience with infrastructure-as-code tools (Terraform, Ansible, or similar).

Additional Technical Skills

• Familiarity with C/C++ for performance-critical modules.
• Working knowledge of JavaScript / React or Flutter for cross-functional collaboration.
• Experience with data management, ETL pipelines, or automation platforms.
• Master's or PhD in a relevant discipline.
• Technical leadership or team building experience.

• Ability to write clean, robust, maintainable code and hold a high bar for engineering quality.
• Fluent in English with strong written and verbal communication skills.
• Comfort working directly with clients and cross-functional stakeholders.
• Out-of-the-box thinking — you bring creative solutions to complex engineering problems.
• A growth mindset — you stay current with industry trends and are eager to adopt new technologies.
• Strong sense of ownership: you see features through from idea to production and beyond.
