Python Developer

Join Nexchar Ventures and Help Decarbonise the Future

Nexchar Ventures is a climate‑technology product manufacturer creating scalable carbon‑negative solutions for a sustainable future.

We build and operate smart bio‑refineries, IoT‑enabled reactors, and ERP‑driven supply‑chains that convert waste biomass into high‑quality biochar and verified carbon credits. From our growing Gurgaon R&D hub, our 50‑plus team is engineering digital tools that link field‑level sensors with cloud analytics to automate every tonne of CO₂ we remove.

We are expanding our engineering organisation and invite mission‑driven developers to shape the tech stack powering climate action.

1️⃣ Python Developer – IoT Systems

Why this role matters

You will design, build and scale the data pipelines and micro‑services that connect thousands of field sensors to our cloud‑based carbon accounting platform. Expect to work with edge devices, PLCs, and AWS IoT Core while keeping latency low and data integrity high.

Key responsibilities

• Architect and develop REST / gRPC micro‑services in Python (Flask or Django) for real‑time device telemetry.(Expertia, ZipRecruiter)
• Integrate industrial protocols MQTT and Modbus for bidirectional control of bio‑reactors and smart meters.(HiveMQ, HiveMQ)
• Implement device provisioning, over‑the‑air updates and secure certificate management.
• Optimise data ingestion, storage and alerting pipelines on AWS IoT + Kinesis / Timestream.
• Collaborate with hardware engineers to validate sensor accuracy, uptime and fault tolerance.(Medium, Apix Drive)
• Write unit / integration tests and participate in code reviews; champion DevOps‑as‑code (Docker, GitHub Actions).

Qualifications

• 3–5 years of professional Python development with production deployments on Flask or Django.(Expertia)
• Hands‑on experience building IoT solutions with MQTT brokers, Modbus RTU/TCP, or similar industrial comms.(arXiv)
• Familiarity with sensor interfaces (RS‑485, SPI, I²C) and edge compute platforms (Raspberry Pi, ESP32, Jetson).
• Working knowledge of cloud services (AWS IoT, Azure IoT Hub or GCP IoT Core) and CI/CD pipelines.
• Bonus: exposure to time‑series databases, Grafana, or predictive maintenance models.

2️⃣ ERPNext / Frappe Developer

Why this role matters

Nexchar’s entire carbon value‑chain—procurement, production, credit issuance and franchise ops—runs on ERPNext. You will extend our multi‑tenant ERP, automate complex workflows and build APIs that tie factory data to finance, ESG and marketplace portals.

Key responsibilities

• Customize and maintain ERPNext modules (Manufacturing, Stock, Accounts) using Frappe Framework hooks and client scripts.(Frappe Forum, Frappe)
• Design DocTypes, dashboards and print formats; keep changes inside custom apps for clean upgrades.(Frappe Forum, Frappe Forum)
• Build REST/GraphQL endpoints to integrate IoT telemetry, blockchain registries and third‑party payment gateways.
• Implement role‑based permissions, automated approvals and BPMN‑style workflows to ensure auditability.(Frappe Documentation, Frappe Forum)
• Optimise database queries, caching and asynchronous jobs (RQ / Celery) for multi‑country scale.
• Create test suites and migration scripts; participate in peer reviews and DevOps releases with Bench.

Qualifications

• 3–5 years developing on ERPNext v13+ / Frappe v13+ with live production roll‑outs.(Frappe Forum)
• Strong Python (OOP, type‑hints) plus JavaScript skills for front‑end scripting.
• Proven experience in API integrations (REST, Webhooks) and third‑party auth (OAuth 2.0, JWT).
• Solid grounding in SQL (MariaDB / PostgreSQL), data modelling and performance tuning.
• Bonus: exposure to Helm / Kubernetes, Redis and automated testing frameworks (PyTest, Playwright).

What we offer

• Mission with impact – measure your code’s contribution in tonnes of CO₂ removed.
• Cutting‑edge stack – IoT edge + cloud, blockchain MRV, and low‑code ERP custom apps.
• Growth & autonomy – join a flat, engineering‑led culture that encourages experimentation.
• Competitive package – salary, ESOPs, learning stipend and on site work (Gurgaon campus).
