About The Position

A software engineer is wanted to join a diverse, multi-discipline, and multicultural team of 8 people responsible for the full technology stack which delivers critical services to some of the largest energy consumers in the world. This is a small but nimble team where contributions will directly impact the end products. The role involves designing and building robust, scalable backend services that form the core of the platform, leveraging modern architectural principles and technologies to create high-quality APIs, manage data effectively, and seamlessly integrate with external systems. This role offers the opportunity to take ownership of significant backend components and drive technical solutions.

Requirements

• 2-5 years of professional backend development experience.
• Strong knowledge and practical experience integrating with various third-party APIs, including understanding authentication mechanisms (OAuth, API Keys), data transformations, and error handling strategies.
• Proficiency in data modelling and working with relational databases (e.g., PostgreSQL) and data warehousing solutions (Snowflake).
• Experience with backend testing frameworks and methodologies.
• Ability to independently analyze, debug, and solve complex backend challenges.
• Excellent communication and teamwork skills.
• Familiarity with cloud platforms (e.g., Azure) and containerization (Docker) is beneficial.
• Strong command of Python and its ecosystem, including FastAPI, SQLAlchemy, Pydantic, and Alembic.
• Proven experience designing and implementing RESTful APIs.
• Demonstrated understanding and practical application of Hexagonal Architecture or similar domain-driven design patterns.

Nice To Haves

• Experience with message queues (e.g., Kafka, RabbitMQ) or background task queues (e.g., Celery).
• Experience with infrastructure-as-code tools.

Responsibilities

• Design, develop, and maintain robust, scalable, and well-documented APIs using Python (FastAPI).
• Apply Hexagonal Architecture principles (also known as Ports and Adapters) to structure backend services, ensuring clear separation between core business logic, application services, and external concerns like databases, APIs, and UIs.
• Design and implement efficient database schemas using SQLAlchemy for relational data and manage data structures for our data platform (Snowflake).
• Lead the development of integrations with third-party vendor APIs, handling authentication, data mapping, error handling, and ensuring reliable data exchange.
• Write comprehensive unit, integration, and API tests to ensure the reliability, performance, and correctness of backend services.
• Partner closely with front-end engineers, product managers, and senior engineers to define requirements, troubleshoot issues, and deliver high-quality features.
• Contribute to CI/CD pipelines and deployment processes, leveraging Docker and Azure.

Benefits

• Great Place To Work® certified company
