Responsibilities
- Design, build, and maintain Python microservices that ingest raw sensor readings and produce derived, structured, or aggregated data outputs
- Collaborate closely with data scientists to integrate statistical and AI models into backend services so they can run reliably in production
- Translate product and domain requirements into maintainable service implementations and data-processing logic
- Contribute to the reliability, scalability, and performance of services across development and production environments
- Implement data validation, error handling, and monitoring to support correctness and resilience of data services
- Work with relational data models, writing efficient and well-structured SQL to support product and analytical use cases
- Participate in improving existing systems through refactoring, performance optimization, and architectural evolution as the platform grows
Required Qualifications
- Bachelor's degree in Computer Science, Software Engineering, or related technical field (or equivalent years of professional experience)
- Professional experience building backend services using Python
- Experience working with microservice-based architectures or service-oriented systems
- Experience contributing to systems where reliability, scalability, and robustness are important design considerations
- Strong SQL skills and experience working with relational data models in production environments
- Understanding of data processing concepts such as transformation, aggregation, and validation
- Ability to collaborate effectively with cross-functional partners, including data scientists and product stakeholders
- Strong problem-solving skills and attention to detail
- Effective communication skills for technical collaboration
- Experience using analytical Python libraries such as pandas, NumPy, and matplotlib
- Exposure to integrating statistical or model-driven logic into backend or service-based systems
- Familiarity with cloud-based deployment environments and containerized services
- Experience implementing or working with observability practices (logging, metrics, alerting)
- Exposure to distributed data processing patterns or event-driven architectures
- The Product Development team operates in a growth-stage environment where systems evolve alongside product needs
- Engineers balance thoughtful design with pragmatic execution, iterating as requirements and scale become clearer
- Team members are encouraged to take ownership of their contributions while learning from peers and shared standards
- Ability to sit for extended periods while working at a computer
- Office setting with remote/hybrid flexibility
