Why this role matters

You will help build the company from the ground up—shaping our culture and having an impact from Day 1 as part of the foundational team.

Senior C++/Qt Backend Engineer

(High-Performance Systems)

Location: Noida (On-site)

Introduction: Who We Are

We are a lean, product-based startup building the next generation of industrial robotics. Our products are deployed in critical, high-stakes environments, including Railways, Oil & Gas, Chemicals & Fertilizers, and Offshore operations.

We are not just writing code; we are building rugged, intelligent machines that operate in the real world.

1. The Mission (Pure Backend Focus)

You will architect the high-performance C++ Backend of our robotics software.

• No UI Work: You will NOT be designing UI pixels or writing QML front-end code.
• The Engine: Your mission is to build the “invisible engine” that processes 50 Mbps of raw scientific data and feeds it efficiently to the UI layer.
• Ownership: You own the threads, the data structures, and the logic.

2. Critical Outcomes (The First 4 Months)

• Architect the Data Ingestion Layer:
• Design a C++ backend capable of ingesting 50 Mbps of live sensor data (from embedded hardware) without dropping packets or consuming excessive CPU.
• Decouple Backend from UI:
• Implement Ring Buffers and Lock-Free Queues to separate high-speed data acquisition threads from the main Qt Event Loop, ensuring the backend never freezes the UI.
• Crash-Proof Concurrency:
• Refactor the threading model to eliminate Race Conditions and Deadlocks using proper synchronization (Mutexes/Semaphores) or lock-free designs.
• Efficient IPC Implementation:
• Establish robust Inter-Process Communication (Shared Memory / Sockets) to allow the C++ backend to exchange data with other Linux processes instantly.

3. Strategic Outcomes (Months 5 Onward)

As the product matures, your focus will shift from “Building the Engine” to “Hardening and Scaling the Ecosystem.”

• Robust OTA & Redundancy:
• Implement Linux A/B Partitioning strategies. You will design the fallback mechanism where the system uses atomic updates to revert to the last known good configuration in case of an update failure, ensuring high availability in remote offshore locations.
• Containerized Deployment:
• Move from manual builds to automated deployment. You will containerize the application (Docker / Podman) and integrate it with Jenkins / GitLab CI to enable seamless remote deployment to the robot fleet.
• Remote Diagnostics Engine:
• Build the internal logic to capture, compress, and transmit critical system logs and core dumps securely to the cloud without saturating the robot’s bandwidth.
• Fleet Monitoring Infrastructure:
• Distinct from simple logging, you will architect the heartbeat and telemetry protocols that allow our central command to monitor the health of robots deployed in railways and chemical plants in real time.

4. Competencies (Must-Haves)

• Qt Core (Backend Only):
• Expert in QObject, QThread, QEventLoop, and Signal/Slot mechanisms. You understand how to push data to QML, but you don’t style it.
• High-Performance C++:
• You handle data at the byte level, preferring Circular Buffers (Ring Buffers) over standard vectors for streams.
• Concurrency Mastery:
• You know when to use Lock-Free programming to avoid thread contention and can manage interactions between Data Acquisition and Processing threads without bottlenecks.
• Design Patterns:
• Competence in Producer-Consumer (for streams), Singleton (hardware managers), and Factory patterns.
• Linux System Programming:
• Comfortable with IPC (Shared Memory, Unix Domain Sockets) and optimizing process priorities.

5. The “Squad” (Your Team)

• Embedded Engineers:
• They push the raw 50 Mbps stream to the OS; you write the drivers to catch it.
• UI / Frontend Developers:
• They handle QML / UX; you provide the data APIs they need.
• Robotics (ROS) Engineers:
• You ensure their heavy algorithms don’t starve your data acquisition threads.
• Testers:
• You ensure your code stands up to their stress testing.

6. Why This Role Defines Your Career

• Deep Backend Engineering:
• Escape the “button styling” trap. This is 100% logic, memory management, and architecture.
• Real Engineering Problems:
• Solve race conditions, memory leaks, and high-velocity data streams.
• Architectural Autonomy:
• You decide how the data moves and choose the patterns. You own the “Engine Room.”

• Proven record of designing and delivering complex networking products from inception to production delivery. 
• Previous experience developing quality software for commercial products.
• Experience with communication systems involving wireless, radio, security and mesh networking technologies is a plus.
• Ability to work in a small team on fast paced projects that have tight deadlines
• Experience using Agile/Scrum methodologies.
• Seeking 10+ years software development experience
• Experience with Embedded real-time systems
• Must be an excellent SW developer. We expect experience developing software C/C++ in Linux. Python and other scripting languages is a plus.
• Target hardware includes Embedded CPU, DSP, and ARM environments
• Experience with Linux development infrastructure, tool chain and build environment.
• Experience developing both Linux device drivers and application software; installing Linux software and configuring embedded Linux systems
• Experience with OSI networking protocols and applications
• Experience and knowledge of Board Support package (BSP) development including board bring up, tool chain creation, and firmware/diagnostics support
• Experience with system development tools, including Source-Level Debuggers, Logic Analyzers, Oscilloscopes, Code Analysis tools, etc.

• Strong knowledge of the Go programming language
• Knowledge of common Go-routine and channel patterns
• Router packages, such as Gorilla Mux
• Development experience in embedded systems and Linux OS environments.
• Have expertise in implementing micro-services (using tools and technologies for messaging, RPC, containerization, etc.), Docker, container, Docker-swarm, Kubernetes, and Helm.
• Cloud-native architecture, Virtualization, Orchestration, VNFM, MANO, VIM (Virtualization Infrastructure Management).
• LCM (Life Cycle Management of microservices and VMs) - Monitoring, Resiliency, High Availability (HA) & Scalability
• Primary Skills: Golang
• Secondary Skill: Microservices
