You’ll work across Python, Node.js, React, and PostgreSQL — integrating Azure billing data, designing APIs, and shipping data-heavy UI in a low-process, high-ownership environment. A strong fit for engineers who are comfortable with incomplete requirements and want direct influence over product and architecture.

- Design and build backend functionality to support billing rules, chargeback logic, and ROI calculation;
- Integrate external billing data sources, including Microsoft Azure billing systems;
- Build and evolve APIs and data pipelines that translate raw billing data into financial insights;
- Implement frontend functionality for metrics, dashboards, and data-heavy UI views;
- Make architectural decisions focused on maintainability and speed;
- Collaborate with founders and product stakeholders in a low-process environment;
- Ensure smooth deployment and delivery workflows using Vercel;
- Improve AI-driven development workflows using tools like Claude or similar LLMs;
- Design systems with strong guarantees around data integrity, auditability, and financial accuracy;
- Identify technical gaps, risks, and architectural improvements and drive solutions proactively.
- MUST HAVES
- 6+ years of experience in full-stack development;
- Strong experience with Python and Node.js in production environments;
- Experience designing and working with PostgreSQL schemas and data models;
- Experience building frontend applications with React or similar frameworks;
- Experience with AWS services in production;
- Experience using AI tools such as Claude, GPT, or similar in development workflows;
- Experience integrating third-party APIs, especially billing or usage-based systems;
- Ability to work with incomplete requirements and build solutions;
- Comfortable in early-stage product environments;
- Professional working proficiency in English;
- Experience integrating frontend tests into CI/CD pipelines;
- Familiarity with observability and usage tracking concepts;
- Upper-intermediate English level.
- NICE TO HAVES
- Experience integrating Azure billing systems or similar APIs;
- Experience building or consuming SDKs;
- Experience with PHP;
- Experience building financial, billing, or cost-allocation systems;
- Familiarity with AI usage metrics, token-based billing, or ROI tracking models;
- Experience with dashboards, tables, filters, and data-dense UI patterns;
- Prior startup or founder-led product experience;
- Exposure to AI tooling workflows.
- PERKS AND BENEFITS
