Senior Backend Engineer - Python/Django

Position : Senior Backend Engineer - (Founding Member)

Position Overview :

As a Founding Senior Backend Engineer - Python-Django/DRF, you will build the core product AI agents, document processing pipelines, and automation workflows that take real accounting work off practitioners' plates.

This is a high-ownership, full-stack role where you work directly with the founders and PM, move fast with AI tools, and are fully accountable for everything you ship.

No black-box vibe-coding if you can't explain it in a code review, it doesn't go to production.

Responsibilities :

- Design and build multi-step AI agents and RAG pipelines using LangChain and LangGraph for real accounting workflows

- Develop document processing pipelines that extract, classify, and normalize semi-structured financial documents (PDFs, W-2s, 1040s, K-1s)

- Build and maintain Python-Django/DRF backend APIs with multi-tenant data models, RBAC, and audit trails for B2B SaaS clients

- Implement human-in-the-loop review queues with confidence thresholds and rule-based overrides for AI-generated outputs

- Design async task workflows using Celery and Redis for long-running document jobs with retry logic and failure visibility

- Collaborate directly with the PM and founders to size work, surface constraints early, and challenge underspecified requirements before building

- Write tests for AI pipeline logic, document parsing edge cases, and multi-step agent flows where silent failures are costly

Must-Have Requirements :

- 4- 8 years of total software engineering experience with at least 2 or 3 years in Python-Django and Django REST Framework in production

- 2+ years building and shipping LangChain-based agents or RAG pipelines to real users (not just tutorials or prototypes)

- Hands-on experience with Celery and Redis for async task processing including retry logic and failure handling

- Demonstrated experience building B2B SaaS products with multi-tenant architecture, RBAC, and audit logging

- Experience building document processing pipelines for semi-structured or scanned documents (extraction, classification, normalization)

- Strong ReactJS skills with ability to own frontend interactions end-to-end without requiring a dedicated frontend engineer

- Working knowledge of PostgreSQL including schema design, indexing, and ability to explain ORM queries in raw SQL

Nice to Have :

- Prior exposure to tax or accounting workflows documents like 1040s, W-2s, K-1s, or financial statements

- Experience with document OCR tools such as Unstructured.io or similar extraction libraries

- Familiarity with AWS or GCP for deployment, and Docker for containerization

- Experience with workflow orchestration tools like Temporal or Prefect for complex multi-step pipelines

- Previous work at a fintech or accounting software company serving CPA or advisory firms

What We Offer :

- Direct collaboration with founders your work shapes the product roadmap from day one

- High-ownership role at a well-funded seed-stage startup with a clear path to senior technical leadership

- Hybrid work setup based in Bengaluru with a fast-moving, technically deep team of 8

- The chance to build AI infrastructure that genuinely transforms how accounting firms operate at scale
