Participate in customer-focused discussions to understand pain points and translate them into technical solutions. Mentor and guide team members, championing best practices and high engineering standards.
- AI Systems: Collaborate on AI-driven features, integrating models or intelligent workflows into platform components.Help design systems that support data pipelines, model inference, and AI feedback loops.
Qualifications:
- 6+ years professional experience building production-grade software.
- Solid backend experience — building services, APIs, and database integrations with Python, Django, or comparable stacks.
- Demonstrated ability to work across frontend and backend contexts with clean, maintainable code.
- Experience with version control, deployment pipelines, and performance optimization.
- A proactive mindset and ability to work independently in a fast-paced startup environment.
Nice to Have:
- Experience building or working with AI agentic workflows, including orchestration, tool usage, and multi-step reasoning systems.
- Strong frontend expertise in React.js, including performance optimization and scalable component architecture.
- Ability to think beyond pure engineering — strong business and product acumen.
- Demonstrated curiosity and interest in working backwards from the customer, identifying real pain points, and translating them into technical solutions.
- Passion for building end-to-end features that create measurable product impact.
Why Join Us?
- Impact: Drive major product areas from inception to production.
