ABOUT THE ROLE

We are looking for a Senior Full Stack Engineer to build web applications that connect back-end data to front-end interfaces and automate business workflows.

MUST HAVES

• Senior-level (5+ years) of hands-on software engineering experience; as the first core software engineer on the team, must possess the architectural maturity to design and implement solutions, set foundational coding standards, and guide and upskill peers.


• 5+ years of programming experience in at least one of the following languages: Java or Python.


• 5+ years of experience developing backend APIs in a data-driven environment.


• 5+ years of experience with datastores such as MySQL, PostgreSQL, MongoDB, or similar long-term stores.


• 4+ years of experience building production frontend applications using React and TypeScript.


• Strong knowledge of REST or GraphQL, RPC, and JSON.


• Working knowledge of a cloud-based environment, with a focus on AWS.


• Experience conducting and leading code reviews.


• Experience impacting a product or project in a tangible, positive manner.


• BS in Computer Science, Engineering, or another technical-related degree.

NICE TO HAVES

• Working knowledge of service-oriented and event-driven system architectures.


• Experience consuming GraphQL APIs from the frontend (Apollo Client or similar).


• Demonstrated use of Kafka, SQS, RabbitMQ, or other messaging frameworks.

• Strong problem-solving skills and a passion for debugging complex issues and maturing code.


• Significant experience with large-scale, high-performance systems, including an understanding of the tradeoffs between consistency and scalability and common patterns for scaling reliable systems through data replication and redundancy.

WHAT YOU WILL DO

• Architect and build full-stack software solutions that power business operations, spanning both backend API development and frontend application building.


• Develop custom web applications that give stakeholders an operational front-end interface to review, monitor, and execute complex business logic in a self-serve manner.


• Merge the modern data stack with software engineering capabilities, including API services, microservices, and workflow orchestration engines.


• Build automated workflows and triggers that instantly sync cross-platform systems.


• Transform static and traditional data/analytics solutions into automated operational workflows, closing the loop between data ingestion, analytical insights, and automated operational execution.
