Develop scalable backend services and REST APIs using frameworks such as FastAPI, Flask, Node.js, or similar technologies.
Design and integrate applications with relational databases, with a strong emphasis on PostgreSQL.
Build end-to-end application functionality spanning front-end, backend, APIs, authentication, and data layers.
Collaborate with data engineers, platform engineers, architects, product stakeholders, and customers to translate business requirements into working applications.
Develop applications and user experiences that integrate with data and analytics platforms.
Drive technical decisions and proactively identify and resolve engineering challenges.
Produce clean, maintainable, well-tested code and contribute to application development standards and best practices.
Communicate technical decisions, tradeoffs, risks, and progress clearly to both technical and non-technical stakeholders.
Take ownership of deliverables and drive projects from requirements through production deployment.

Must-Have Qualifications:

Strong professional experience in full-stack application development.
Demonstrated experience designing and building production Single Page Applications (SPAs).
Strong hands-on experience with modern front-end frameworks such as React, Angular, or equivalent.
Strong JavaScript and TypeScript development experience.
Experience building backend applications, services, and APIs using technologies such as FastAPI, Flask, Node.js, or equivalent frameworks.
Strong experience working with relational databases, including database design, queries, application integration, and performance considerations.
Hands-on experience with PostgreSQL or comparable relational database technologies.
Experience integrating front-end applications with backend APIs and data services.
Understanding of modern application architecture, authentication, security, testing, and deployment practices.
Ability to independently take a feature or application from concept through implementation and delivery.

Nice-to-Have Qualifications:

Experience developing and deploying Databricks Apps.
General hands-on experience with the Databricks Data Intelligence Platform.
Experience integrating custom applications with Databricks data, APIs, SQL warehouses, or other platform capabilities.
Familiarity with Databricks technologies such as Unity Catalog, Databricks SQL, Delta Lake, and Lakehouse architectures.
Experience building data-intensive or analytics-focused web applications.
Cloud application development experience with AWS, Azure, or GCP.

What We're Looking For

Beyond technical expertise, success in this role requires strong ownership and interpersonal skills.
Bias Toward Action: You are comfortable operating with ambiguity, making informed decisions, and moving work forward without waiting for perfect information.
Communication: You communicate proactively and clearly, raise risks early, and can effectively collaborate with engineers, business stakeholders, and customers.
Leadership & Ownership: You take responsibility for outcomes rather than simply completing assigned tasks. You can lead technical discussions, influence architecture and engineering decisions, and help other team members succeed.
Problem Solving: You enjoy breaking down complex business and technical problems and turning them into pragmatic, scalable solutions.
Collaboration: You work effectively across application development, data engineering, platform, architecture, and business teams and are comfortable working in a fast-paced, collaborative environment.
