Senior Full Stack Software Engineer – Passenger Flow Modelling

We are seeking a Senior Full Stack Engineer with a strong foundation in Python development and experience in mathematical modelling for a short-term project focused on passenger flow modelling . The primary task will involve interpreting pre-defined modelling logic and translating it into an efficient, Python-based solution, which will then be integrated with an existing UI (ReactJS) and API .

This is an ideal opportunity for someone who excels in backend development , is comfortable with integration work , and has experience with large-scale, performant systems.

Key Responsibilities:

• Interpret and Implement Mathematical Logic: Understand and translate pre-defined passenger flow modelling logic into efficient Python code.
• Backend Development: Build robust and maintainable backend components, utilizing Python-based frameworks like Flask, FastAPI, or Django.
• API Integration: Develop and integrate with existing RESTful APIs, ensuring seamless data flows between backend and frontend components.
• UI Integration: Collaborate with front-end developers to ensure proper integration of backend logic with the ReactJS user interface.
• Optimization: Continuously optimize the Python code for performance, ensuring minimal computational cost and maximal scalability.
• Collaboration: Work closely with project stakeholders to refine requirements, align expectations, and deliver on technical needs.
• Documentation and Code Quality: Write high-quality, maintainable code with thorough documentation. Conduct code reviews to ensure best practices are followed.

Required Skills and Qualifications:

• Advanced Python skills with experience in backend frameworks like Flask , FastAPI , or Django .

• Experience with libraries like NumPy , Pandas , SciPy , or any others commonly used in data processing or modelling.
• Strong understanding of data structures , algorithms , and complexity analysis .

Mathematical or Computational Modelling:

• Experience with implementing mathematical models in Python, particularly in fields such as transportation or flow analysis .
• Ability to interpret and convert pre-defined modelling logic into working code.

Full Stack Development:

• Proven experience in full stack development , with the ability to work on both backend (Python) and frontend (ReactJS).
• Familiarity with state management tools such as Redux or React Query .
• Experience working with REST APIs , integrating backend logic with UI components and ensuring smooth data flow between systems.
• Solid understanding of SQL and/or NoSQL databases (e.g., MySQL , PostgreSQL , MongoDB ).
• Experience designing data models and optimizing queries for performance.

Cloud and Containerization:

• Experience working with cloud platforms like AWS , Azure , or Google Cloud .
• Familiarity with Docker , Kubernetes , or other containerization technologies, particularly for deployment and scaling of applications.
• Proficiency in Git for version control.
• Experience with CI/CD pipelines for streamlined development and deployment processes.
• Strong analytical and problem-solving skills, with the ability to optimize code for performance and scalability.
• Familiarity with performance optimization techniques for computational models, particularly when dealing with large datasets or complex calculations.
• Excellent communication skills, with the ability to collaborate effectively with cross-functional teams, including front-end developers, project managers, and stakeholders.
• Ability to document and explain complex technical concepts clearly.

Nice to Have:

• Experience with transportation or logistics systems , particularly related to passenger flow , traffic analysis , or queueing theory .
• Familiarity with integrating Python-based models into enterprise systems and understanding the challenges around this process.

Location:

• Hybrid. Office located in London. (Hayes area).
• Office presence required: Yes.
• Frequency: 2-3 times a week at the office.
