Engineer – RF & Secure Communications

Job Description

The Role: You will be design the Link Architecture that defines how command network for UAVs operates and receives HD video without signal dropouts or interference. This is not about setting up WiFi; this is about Link Budgets, Fresnel Zones, as also ensuring continuous, high performance and secure communications in challenging RF environments.

What You Will Do

• Define the RF strategy taking it to Critical Design & Prototype stage.
  

• Select the critical radio hardware e.g. MANET/Mesh based on SWaP-C analysis.
  

• Simulate antenna placement to ensure the aircraft has no "blind spots" during dynamic flight profiles and varied banking angles.
  

Key Responsibilities

• Link Analysis: Calculate detailed Link Budgets for C2 and Video links, accounting for terrain, airframe shadowing, and fade margins.
  

• Hardware Selection: Evaluate and select MANET Radios and configure them for optimal throughput vs. range.
  

• Interference Mitigation Strategy: Design the architecture for Frequency Hopping Spread Spectrum (FHSS) and advise on antenna diversity (MIMO) to mitigate multi-path interference and signal degradation.
  

• Communications Security: Implement AES-256 encryption standards and manage advanced network security protocols.
  

Requirements

Minimum Qualifications:

• B.E./B.Tech in Telecommunications, Electronics & Communications (ECE) or RF Engineering.
  

• 1-3 years of experience in RF System Design, Wireless Communications or Aerospace Electronics.
  

• Proven capability to pick and configure mission-critical radio hardware (MANET/Mesh architectures) based on strict SWaP-C (Size, Weight, Power, and Cost) trade-offs.
  

• Core Technical Knowledge: Applied understanding of signal propagation physics, antenna metrics (Gain, VSWR, Polarization), modulation formats (QPSK, OFDM), and basic UAV protocol ecosystems.
  

Preferred Qualifications:

• M.Tech/MS in RF or Microwave Engineering.
  
• Experience with Software Defined Radios (SDR).
  
• Proficiency in 3D RF simulation and modeling software (ANSYS HFSS or CST Studio Suite).
  

Skills & Abilities:

• Simulation: Proficiency in MATLAB (RF Toolbox), CST Microwave Studio, or HFSS.
  
• RF Physics: Deep understanding of Gain, VSWR, Polarization, and Propagation models (Longley-Rice).
  
• Hardware: Experience with Spectrum Analyzers and Vector Network Analyzers (VNA).
  

Benefits

Rewards Plus

• Opportunity: To work in the hottest sector of technology today, and to work with cross-functional teams making emerging-tech systems. We are building high-speed autonomous systems.
  

• Impact: You are joining an iDEX winner team building next-gen aerospace technologies. As we scale, you will see accelerated growth. The runway is clear for take-off.
  

• Startup Vibe: This is a unique Firster’s Team opportunity to join 0-1 builders and help in building the company’s DNA.
  

The Compensation, Health, Wellness & Professional Development

• Compensation: Competitive Market Salary + Performance-Based Incentive.
  

• Comprehensive Allowances: Structured House Rent Allowance (HRA) and standard Conveyance Allowance.
  

• Digital & Workplace Enablement: Dedicated allowances covering Mobile & Internet connectivity, and monthly fixed value food coupons.
  

• Health & Wellness: Fixed Medical Allowance integrated into monthly compensation to support ongoing medical and wellness needs.
  

• Continuous Growth: Direct reimbursement for Professional Development and technical certifications, as specified/applicable to the role.
  

• Dynamic Work Culture in NCR: A collaborative, 'builder-first' environment in NCR (Gurgaon), which values institutional discipline alongside rapid startup innovation.
  

• Field & Travel Support: On deployment for travel on project work(if applicable).
