Role Overview

We are seeking a high-caliber Senior RF Systems Engineer to lead the development of next-generation situational awareness and electronic warfare (EW) platforms. You will be responsible for the full lifecycle of RF subsystems, from initial research (TRL 1) to field-tested operational prototypes (TRL 7+). Your work will directly impact projects such as autonomous drone detection, FHSS signal classification, and distributed SIGINT mesh networks.

Key Responsibilities

RF Design & Integration

• Design and optimize RF front-ends for unmanned aerial systems (UAVs) and ground-based detection stations.
• Develop hardware and firmware for high-speed FHSS (Frequency Hopping Spread Spectrum) detection and mitigation.
• Architect and implement Mesh Networking protocols for distributed sensor arrays (e.g., FPV-borne SIGINT mesh).

Signal Intelligence (SIGINT) & Electronic Warfare

• Develop algorithms for passive RF geolocation and signal classification.
• Engineer solutions for Drone Detection, focusing on identifying digital and analogue transmitting signatures even under heavy jamming.
• Design and test spoofing detection systems for Galileo and GPS navigation.

Field Validation & Testing

• Lead field testing of RF prototypes in relevant operational environments to validate TRL exit criteria.
• Analyze battlefield RF signatures to refine "kill zones" and improve EW training simulators.
• Collaborate with the software team to integrate RF data into C2 (Command and Control) dashboards.

Technical Requirements

SDR Mastery

Expert proficiency with Software Defined Radio platforms (HackRF, BladeRF, Ettus USRP) and GNU Radio.

Signal Processing

Deep understanding of digital modulation (OFDM, FSK), FFT analysis, and hopping pattern reconstruction.

Hardware

Experience with PCB layout for RF applications (up to 6GHz), antenna design, and impedance matching.

Frequency Bands

Experience working across 300–600 MHz (FHSS), 2.4 GHz, and 5.8 GHz bands.

Tools

Proficiency in MATLAB/Simulink, Python, or C++ for real-time signal analysis.

• Proven experience with SAW (Surface Acoustic Wave) filters and LNA (Low-Noise Amplifier) design/integration.

Preferred Qualifications

• Knowledge of FPGA development for low-latency signal processing (Verilog/VHDL).
• Background in military-grade communication protocols and LPI/LPD (Low Probability of Intercept/Detection) systems.

Logistics & Impact

• Location: Kyiv (Hybrid/Field testing required).

Role Overview – Product Designer

We are looking for a curious, product-minded designer who enjoys solving complex UX challenges and is excited about the future of AI-powered product design.

Beyond strong UX fundamentals, we’re looking for someone who actively explores AI tools and continuously experiments with new ways to improve design workflows. The ideal candidate already uses tools such as Claude, GitHub Copilot, Figma Make, or similar AI assistants to accelerate research, ideation, prototyping, documentation, and day-to-day product design.

We’re building a collaborative design culture where knowledge is shared openly, experimentation is encouraged, and every designer contributes to improving how the team works. If you enjoy discovering new tools, creating smarter workflows, and helping others adopt them, you’ll fit right in.

The designer will collaborate closely with Product Managers, Engineers, and Senior Designers to translate complex product logic into intuitive user experiences while helping shape the future of our AI-enabled design process.

Key Requirements

AI & Innovation
 

• Strong interest in AI-powered product design and hands-on experience with tools such as Claude, GitHub Copilot, Figma Make, or similar
• Experience using AI to accelerate UX workflows, prototyping, documentation, user flows, research, or content generation
• Passion for experimenting with emerging AI technologies and integrating them into everyday design work
• Experience building custom prompts, reusable AI workflows, internal AI assistants, or other productivity solutions is a strong plus
• Curiosity to continuously explore new AI capabilities and share discoveries with the team
  
  Product Design
• Strong wireframing, interaction design, and information architecture skills
• Ability to structure complex product logic into clear, intuitive user experiences
• Experience designing complex B2B SaaS products or enterprise applications
• Strong analytical and systems thinking
• Ability to transform ambiguous business or technical requirements into scalable UX solutions
• Attention to usability, consistency, and scalability
  
  Collaboration
• Strong communication and collaboration skills across Product, Design, and Engineering
• Open to giving and receiving feedback
• Enjoys working in a collaborative environment where teammates actively mentor and support one another
• Willingness to document ideas, share best practices, and help improve team processes
  
  Collaboration & Contribution
  
  This role goes beyond designing screens.
  
  You’ll contribute to building better design processes, improving team efficiency, exploring new AI capabilities, refining our Design System, and helping shape the future of product design within the company.
  
  We’re looking for someone who enjoys ownership, continuous learning, and discovering better ways of working—not only for themselves, but for the entire team.
  
  Focus Areas
• Designing intuitive user flows for complex B2B products
  AI-assisted prototyping and rapid design exploration
• AI-enhanced UX documentation and workflow optimization
• Building scalable design patterns and contributing to the Design System
• Collaborating with Engineering and Product throughout the SDLC
• Exploring and integrating new AI tools into the design process
• Sharing AI workflows, prompt libraries, and best practices across the team
• Improving team productivity through automation and continuous process improvement

You're the only designer. Brand, motion, website, product, presentations — all yours. Full ownership; you decide what the company looks like and defend it directly to the founder.
 

Brand first. Logo, identity, visual language, motion, landing page — from a blank page. Not "make it look nice" — make it recognizable.

AI-first. One person can't cover this scope without it. AI tools are already part of your process, and it shows in your output.

No incoming task queue. You bring directions, propose options, push back on weak decisions. Waiting for tasks won't work here.
 

What You'll Do

Brand & identity — Visual language from scratch: logo system, color, typography, grid, iconography, illustration. Living brand guidelines used by both the team and AI agents. One brand across all touchpoints.

Motion — Motion as brand language: animated logo, landing page animations, payment explainer videos, promo content. Micro-animations in the product. You set the movement principles — timings, curves, hierarchy.

Landing page & web — Main website from structure to live: visuals, responsive, states. You ship it with the frontend team (Next.js + Tailwind) and verify in the browser, not just hand off a mockup.

Product — Audit and rework of dashboards, transaction tables, settlement, chargebacks, onboarding, case management. You own visuals, UX, and the design system: Figma library, tokens, components, code sync.

Marketing — Investor and sales decks, one-pagers, infographics, LinkedIn templates, conference materials.

AI & automation — AI at every stage: concepts, variations, image/video generation, prototyping. Automate routine, keep guidelines in a format AI agents can actually use.
 

Requirements

Must have

• 3+ years with real experience in both brand and product
• Portfolio that shows full brand systems (not just logos) taken from blank page to market
• Motion at brand-language level — a system of movement, not just pretty animations; implementable on the web
• Product interfaces: dashboards, tables, complex forms, B2B or SaaS
• Design system ownership: built, maintained, synced with code
• Strong visual taste; expert-level Figma
• Landing pages end-to-end with understanding of how frontend builds them
• Experience as the only designer or in an equally autonomous role
• AI genuinely in your daily workflow — you adopt tools, apply judgment, ship production-quality output
• Proactive: you bring ideas, push back, drive to done
• Curiosity about fintech: acquiring, settlement, chargebacks — domain understanding matters
• English: confident reading/listening required; spoken is a strong plus
   

Nice to have

• Fintech / payments / B2B SaaS background
• Rebranding or market-entry brand work
• Redesigning a live product with legacy
• 3D, illustration, video editing
• Can build pages yourself: Framer, Webflow, or code
• Copywriting and positioning
