Senior Consultant – Python Progtamming (Full Stack)

Job Title: Senior Consultant Python Progtamming (Full Stack)

Career Level: D2

Introduction to role:

Are you ready to harness modern engineering to help transform how life-changing medicines reach patients Join a high-impact team building secure scalable products that turn data into better decisions across our business. Your work will shorten feedback loops increase the reliability of critical platforms and directly influence how quickly we can move from scientific discovery to realworld outcomes.

Operating at a senior level you will own complex services end to end from shaping solution architecture to hands-on coding testing and deployment. You will raise the engineering bar through clean code robust patterns and strong DevOps practiceswhile collaborating closely with product architecture and data teams to deliver value in short measurable increments.

Do you thrive on taking ideas from whiteboard to production instrumenting what matters and iterating fast This is a chance to lead by example in an Agile environment aligning modern Python React/ and AWS-native capabilities to solve meaningful problems at scale.

Accountabilities:

- Product-Focused Delivery: Translate outcomes into clear increments with product and data partners; plan and execute delivery within Agile/Scrum ceremonies to create measurable impact.

- Backend Services (Python/FastAPI): Design and build secure scalable APIs and microservices; apply async I/O and multithreading where it adds throughput and reliability; enforce robust error handling logging and performance optimization.

- Frontend Engineering (React/ Build responsive accessible components and pages; optimize for performance maintainability and reuse; integrate modern UI patterns.

- API and Systems Integration: Integrate frontend apps with backend systems and external services; implement and harden authentication/authorization flows using JWT and OAuth.

- Cloud-Native Operations (AWS/EKS): Containerize services with Docker; implement CI/CD with GitHub and ArgoCD; apply IAM best practices; design for resilience observability and cost efficiency.

- Data and Storage: Model query and optimize against PostgreSQL and Snowflake; ensure data integrity and reliability in high-traffic scenarios.

- Quality and Reliability: Drive a testing culture with Pytest and Jest; lead code reviews and refactoring; champion secure coding and progressive hardening of services.

- Engineering Excellence: Apply OOP SOLID DRY and KISS; design modular testable architectures; establish reusable patterns and internal libraries to accelerate delivery across teams.

- Ways of Working and Mentorship: Contribute to a culture that embraces AI and modern digital tools to improve outcomes; coach peers share knowledge and help scale best practices across squads.

- Business Impact: Reduce lead time and defects improve system uptime and user experience and ensure solutions align to strategic priorities that speed and strengthen decision-making across the enterprise.

Essential Skills/Experience:

- Were looking for an experienced Full Stack Engineer with 8 to 10 of experience and strong expertise in Python backend development and ReactJS / frontend development to join our team.

- 5 years of skill relevanyt experience in full stack development

- Strong backend experience in Python using FastAPI (must) Flask (good to have).

- Frontend expertise in ReactJS and TypeScript

- Experience building and integrating RESTful APIs

- Strong understanding of authentication and authorization using JWT and OAuth

- Experience with PostgreSQL Snowflake

- Knowledge of microservices multithreading and async I/O

- Experience with Docker GitHub CI/CD pipelines and ArgoCD

- Testing experience using Pytest and Jest

- Comfortable working in Agile/Scrum teams

- Strong AWS knowledge is required including EKS IAM S3 and Identity Management and ability to articulate them clearly.

- Strong foundation in Object-Oriented Programming (OOP) and software design principles

- Practical experience applying SOLID principles DRY KISS and clean coding practices

- Ability to write modular reusable scalable and maintainable code

- Experience with code reviews refactoring and improving code quality over time

- Good understanding of design patterns separation of concerns and writing testable application architecture

- Focus on error handling logging performance optimization and secure coding practices

Desirable Skills/Experience:

- Exposure to Agile.

- Familiarity with modern UI libraries or styling frameworks such as Shadcn UI and Tailwind CSS

When we put unexpected teams in the same room we unleash bold thinking with the power to inspire life-changing -person working gives us the platform we need to connect work at pace and challenge perceptions. Thats why we work on average a minimum of three days per week from the office. But that doesnt mean were not flexible. We balance the expectation of being in the office while respecting individual flexibility. Join us in our unique and ambitious world.
