Backend Engineering: Develop scalable backend services and integrations using TypeScript or Python.
Data Engineering: Design, maintain, and optimize SQL-based data pipelines.
Client Engagement & Implementation: Act as a technical partner to our clients. You will interface directly with stakeholders to gather requirements, demo solutions, and ensure successful adoption of our tools.
On-Site Discovery: Travel to client sites periodically to understand their operational reality, identify pain points, and deploy solutions in the field.
Collaboration: Collaborate closely with other developers and business stakeholders to deliver digital solutions.
Mentorship: Mentor junior and intermediate developers through code reviews, pair programming, and technical guidance.

Language Proficiency: Expert knowledge and experience with TypeScript (or Python as an equivalent).
Data Skills: Deep knowledge of SQL and database design.
Problem-Solving: Strong problem-solving skills—you’re resourceful, curious, and comfortable tackling ambiguous problems, finding creative solutions even when clear answers don’t yet exist.
Communication: Excellent communication skills—able to collaborate, document, and explain your work clearly.
Autonomy: Self-directed, motivated, and organized — you thrive in a fast-moving environment without micromanagement.
