Job Description: Communication & Control Systems Engineer (Mesh Networks)

Role Overview

We are looking for an M.Tech engineer with expertise in communication and control systems for mesh networking technologies. You will design, implement and test self\-forming, self\-healing mesh links for drone swarms and ground units. You will also tie those links into the command\-and\-control loops that keep the platforms flying safely.

Key Responsibilities

• *Mesh communication design**

• Design and implement mobile ad\-hoc / mesh networks (MANET, FANET) for drone\-to\-drone, drone\-to\-ground and ground\-to\-ground links.
• Select and configure radios and protocols (e.g. 802\.11s, BATMAN\-adv, OLSR, Silvus/Doodle\-class MANET radios, LoRa mesh) for range, throughput and latency targets.
• Develop link\-budget, RF propagation and coverage analyses for line\-of\-sight, beyond\-line\-of\-sight and high\-altitude terrain.
• Design routing, topology control and self\-healing behaviour for networks of changing size and shape.

• *Control systems**

• Design and tune control loops for UAV flight, payload and gimbal systems, including latency\-tolerant command\-and\-control over the mesh.
• Integrate telemetry and command links (MAVLink and similar) with flight controllers (PX4 / ArduPilot) and ground control stations.
• Develop distributed / cooperative control for swarms: formation keeping, consensus and task coordination over the network.

• *Security \& resilience**

• Implement link encryption, authentication and key management suited to defence use.
• Design for jamming and interference resilience: frequency hopping, adaptive modulation, multi\-band fallback.

• *Simulation, integration \& testing**

• Model networks and control behaviour in simulation (ns\-3, OMNeT\+\+, MATLAB/Simulink) before hardware trials.
• Integrate radios, antennas and embedded hardware on airframes and ground nodes; support EMI/EMC checks.
• Plan and run field trials, measure throughput, latency, packet loss and range, and feed results back into the design.
• Prepare technical documentation, test reports and inputs for tenders and RFIs.

Required Qualifications

• **M.Tech** in Communication Systems / Electronics \& Communication / Control Systems / Wireless Networks / Avionics or a closely related field.
• Strong fundamentals in digital communication, RF and wireless networking: modulation, coding, link budgets, MAC and routing.
• Hands\-on experience with **mesh / ad\-hoc networking** (802\.11s, BATMAN\-adv, OLSR, AODV or MANET radios).
• Strong grounding in **control theory**: PID, state\-space, stability analysis and digital control.
• Proficiency in **MATLAB/Simulink** and at least one network simulator (**ns\-3, OMNeT\+\+** or equivalent).
• Programming in **C/C\+\+ and Python**; working knowledge of Linux networking.
• Demonstrated project work on wireless or UAV communication: thesis, publications, competitions or industry projects.

Preferred Skills

• Software\-defined radio (SDR) experience: GNU Radio, USRP, HackRF or similar.
• Experience with MAVLink, PX4 / ArduPilot and ground control stations.
• Embedded development on ARM / STM32 / NVIDIA Jetson / OpenWrt platforms.
• Familiarity with ROS / ROS 2 and multi\-agent / distributed control.
• Knowledge of anti\-jamming techniques, FHSS / DSSS, and secure communication protocols.
• Antenna basics and RF test equipment (spectrum analyser, VNA).
• Awareness of WPC/ETA spectrum rules, DGCA Drone Rules 2021 and defence QA documentation.

Key Attributes

• Systematic debugging from RF layer to application layer.
• Clear technical writing and communication.
• Ownership mindset and comfort in a fast\-moving startup team.
• Willingness to travel for field trials, including high\-altitude and remote locations.

Eligibility

• Indian nationality is required, as the role involves defence\-related projects.
• Candidates may need to undergo background verification and security clearance.

How to Apply

Applications without the mandatory documents below will not be considered.

• *Mandatory documents**

1\. **Detailed CV** in the prescribed format, covering education, communication/control tools used, and mesh or UAV communication projects with your role in each.

2\. **Experience certificate(s)** on the employer's letterhead, signed and stamped by an authorised signatory, stating designation, period of employment and nature of work in communication / control systems.

3\. **M.Tech degree certificate and marksheets** (provisional certificate accepted for recent graduates).

• *Supporting documents (preferred)**

• Project reports, test results, code repositories or publications.
• M.Tech thesis abstract.

Send all documents as PDFs to **careers@p9e.in** with the subject line **"Application – Communication \& Control Systems Engineer"**. Shortlisted candidates must produce originals for verification.
