About Scatterlink

Scatterlink is a product-based SaaS company tackling one of the toughest challenges in heavy industry —
inventory visibility.

We build
IoT-powered software
that connects physical assets from surface and underground operations into the digital world.

Our platform tracks inventory in real time, integrates with ERPs like Microsoft D365, SAP, and Oracle, and delivers instant operational insights.

If you love solving complex backend challenges, integrating large-scale systems, and designing architectures that move millions of data points in real time — this is your place.

Role Overview

We're looking for a
Senior Backend Engineer
who can own the integration and backend stack — from designing robust APIs to building scalable, multi-tenant microservices that can handle high data volume and reliability requirements.

You'll work directly with the core engineering team to evolve our monolith into a modern, event-driven microservices architecture and build deep ERP integrations that run seamlessly across AWS and GCP environments.

What You'll Do

  • Design, develop, and optimize
    RESTful APIs
    for large-scale integrations (D365, SAP, Oracle).
  • Implement
    error handling, batching, throttling, and retry mechanisms
    for stable real-time sync.
  • Convert an existing monolithic backend into a
    microservices-based architecture
    .
  • Build secure authentication and authorization flows (JWT/OAuth2).
  • Develop event-driven systems using queues, pub/sub, or serverless patterns.
  • Manage data pipelines and ETL workflows between Scatterlink and ERP systems.
  • Optimize
    PostgreSQL
    queries, indexes, and transactions for high throughput.
  • Work with
    AWS/GCP
    for deployment, scaling, and monitoring.
  • Collaborate with front-end and mobile teams to align API and data flows.
  • Ensure performance, security, and reliability across multi-tenant environments.

You Should Have

  • 5–8 years of backend development
    experience in SaaS or product-based companies.
  • Strong command of
    Python
    and TypeScript.
  • Proven experience building RESTful APIs and integrating with enterprise systems.
  • Expertise in PostgreSQL, including query optimization and schema design.
  • Deep understanding of
    microservices, message queues, and event-driven design
    .
  • Solid experience with
    AWS (Lambda, ECS, SQS, API Gateway) or GCP equivalents
    .
  • Knowledge of authentication protocols (JWT, OAuth2, SSO).
  • Familiarity with
    real-time sync
    and ERP integration patterns.
  • Startup mindset — hands-on, fast-moving, and ownership-driven.

Bonus Points

  • Experience with Microsoft D365 F&O, SAP, or Oracle ERP integrations.
  • Knowledge of GraphQL or gRPC.
  • Exposure to data mapping, API gateways, and middleware systems.
  • Prior work in IoT or inventory management domains.

Location

  • Mumbai-based (work from office)
  • Monday to Friday | Alternate Saturdays
