About Sourcewiz
About
Sourcewiz is on a mission to revolutionize B2B commerce! The world of e-commerce changed back in the early 2000s when a few software empowered all retailers to create digital experiences for their customers seamlessly. Even though B2B Commerce is much larger than B2C commerce, it still runs essentially offline, and players who want to create B2B E-commerce experiences have to rely on software that is not meant for B2B but built primarily for B2C.
We are here to change that. We are building a SaaS platform to digitize B2B commerce businesses, factories, wholesalers, and distributors worldwide. We started with factories and have onboarded 800+ global factories (exporters) in India just in 11 months of launch and are now launching internationally.
If you want to disrupt a Trillion$+ space, Sourcewiz is the place to be.

Requirements
- 3–5 years of experience as a Product Engineer, ideally in a startup or B2B SaaS environment
- Strong proficiency in React.js for front-end development
- Strong proficiency in Python, with hands-on experience in Django for back-end development
- Solid understanding of REST APIs, databases (SQL/NoSQL), and system design fundamentals

- Strong debugging and problem-solving skills
Good to Have
- Familiarity with the Model Context Protocol (MCP) for securely connecting LLMs to external tools and APIs.
- Experience building conversational AI interfaces or managing complex multi-turn chatbot state across various platforms and channels.

- Exposure to cloud infra (AWS/GCP/Azure), Docker, and CI/CD pipelines.
- Experience with LLM evaluation/monitoring tools (Ragas, LangSmith, Langfuse, or similar).
- Experience with data visualization libraries (Recharts, D3.js, Chart.js).
- Familiarity with compliance-aware or explainable AI design in regulated domains.
What We Look For In Candidates
- Customer Obsession – A genuine curiosity about how your code impacts the customer's experience, not just whether it compiles.
- Ownership – You drive features to completion, chasing down blockers instead of waiting on them.
- Stakeholder Understanding & Management – You know when to loop in Product, Design, or Business to unblock yourself fast.
- High Standards – You hold your own code to a higher bar, even when no one's checking.
- Disagree and Commit – You debate technical decisions hard, then commit fully once the call is made.
- Simplify Relentlessly – You reach for the simplest working solution, not the most "clever" one.
