Senior Engineer (Python)

The Senior Python Engineer will be responsible for architecting and implementing complex back-end systems, designing RESTful APIs, optimizing database performance, and leading technical decisions regarding architecture and deployment strategies. This role requires close collaboration with product and design teams to deliver high-quality solutions.

Candidates should have 5-7 years of professional software engineering experience, expert-level proficiency in Python (preferably with frameworks like Django or Flask), and strong knowledge of relational and NoSQL databases like PostgreSQL and MongoDB. Experience with cloud platforms such as AWS or GCP and familiarity with containerization technologies such as Docker are also crucial.

Essential technical skills for the Senior Python Engineer role include proficiency in Python, experience with database design and management, REST/GraphQL API development, and familiarity with testing frameworks like Pytest. Knowledge of CI/CD tools, Docker, Kubernetes, and performance monitoring is also valuable for success in this position.

The work environment is hybrid, tailored to encourage flexibility and productivity. Although based in NYC, our company values work-life balance and offers a range of benefits, including competitive salary, equity options, and comprehensive health coverage.

As a Senior Python Engineer, you will not only contribute to critical projects but will also have the opportunity to mentor junior engineers, influence important architectural decisions, and grow your technical skill set through innovative projects and professional development programs.
