Jobs at Djinni

Antenna / RF Front-End Engineer (Contract)

About the Role

You'll design the antenna and RF front-end at the heart of a counter-UAV radar sensor — radiating elements, arrays, and feed networks — taking them from concept through EM simulation to measured validation. This is a contract engagement, so you'll need to work independently and contribute quickly. We care most about breadth across antenna design methods on a master's-level foundation; senior experience is a strong plus. You'll have access to high-end measurement facilities — including anechoic-chamber time in Kyiv (paid travel) — to characterize and iterate on real hardware, not just simulate. This is a key role to ensure our first launch cements our reputation in the industry  - make your mark with Valkyrie!

What You'll Do

• Design and optimize antenna elements and arrays — single-element and phased-array — for mmWave operation
• Evaluate tradeoffs across frequency bands and packaging: select the band and topology that best balance range, resolution, aperture size, and environmental performance for a given sensing requirement
• Design corporate-fed and series-fed feed networks for phased-array and MIMO systems, controlling amplitude/phase distribution to hit beamforming, sidelobe, and radiation-pattern targets
• Prototype and compare integration approaches — substrate-integrated waveguide (SIW), launch-in-package, and alternatives — to find the best fit for compact integration
• Model and optimize performance — gain, beamwidth, sidelobe level, VSWR/S11, mutual coupling, scan range, grating-lobe behavior — against sensing requirements
• Design MIMO arrays for multi-channel sensing: element spacing, channel isolation, and virtual-aperture formation for angular resolution
• Validate designs on the bench (VNA, anechoic/OTA range), correlating measured results against simulation and documenting deviations
• Work directly with the DSP and radar-systems engineers we're hiring in parallel — antenna, signal processing, and architecture designed together, not in isolation. You'll have real influence over the system design, not just your own slice
• Design to the RF front-end architecture — channel count, transceiver interface, phase coherence — and feed antenna feasibility back as the system evolves
• Prepare finished antenna and feed-network designs for handoff: specify antenna-critical constraints and review layout through bring-up

Required Qualifications 

• Master's in Electrical Engineering, Microwave/RF Engineering, or a closely related field — or equivalent hands-on antenna design experience with the skills below. PhD a plus
• Prior work on radar or RF sensing systems, not communications-only antenna work
• Hands-on experience across multiple antenna design methodologies: SIW, launch-in-package, phased arrays, MIMO systems, series-fed and corporate-fed networks. Breadth here matters more to us than years
• Strong feed-network fundamentals: power dividers, phase shifters, impedance matching, loss/isolation and beam-squint tradeoffs
• MATLAB/Simulink for array-factor synthesis, pattern analysis, and beamforming/system-level modeling (e.g. Antenna and Phased Array System Toolboxes)
• A track record of carrying designs from concept through simulation, prototyping, and measurement validation — not simulation alone.
• Proficiency with EM simulation software (HFSS, CST Microwave Studio, or equivalent)

Preferred / Bonus

• Working knowledge of multilayer PCB constraints (stackup, manufacturability) — enough to hand off cleanly to a PCB engineer

Engagement Details

• Type: Contract / consulting
• Rate: [TBD]
• Duration: [TBD]
• Location: Remote/Hybrid
  • Hybrid: Temporary travel to Kyiv for on-site testing, heavily preferred (expenses paid) — primarily anechoic-chamber characterization of candidate designs, with possible field testing.
• Long-term: Strong performance could lead to an ongoing or permanent role.
• Start: ASAP

About the Role

We've already proven the concept of a counter-UAV radar sensor with a first-generation prototype. This role owns the redesign that carries those lessons into a production-grade sensor, architected from requirements up, with the systems planning to do it right. You'll also own the system architecture, from the waveform, detection strategy to the system-level requirements and budgets that define it. You'll drive the RF chain and transceiver architecture hand-in-hand with the antenna engineer, converging on what's actually feasible to build while setting the DSP chain direction. Your success is our success - make your mark with Valkyrie Dynamics.

What You’ll Do

• Own the radar waveform and detection strategy
  • Chirp/FMCW design
  • Range-Doppler processing detection budgets (SNR, integration, CFAR)
  • Angle estimation to detect small, low-RCS UAV targets at high closing velocity
• Define and maintain the system-level requirements and budgets
  • Detection range, range/Doppler/angular resolution, update rate, power, thermal, and size
  • Write verifiable requirements so that meeting them validates the sensor
• Evaluate approaches across the integration spectrum, cascaded transceiver ICs, an integrated system-on-module, or a discrete RF front-end
  • Collaborate with the antenna engineer on a viable solution for channel count, LO/clock distribution, and phase-coherence strategy across the array
• Own and control the interfaces between subsystems
  • Ensure end-to-end signal chain from antenna to detection output holds together as one coherent system including:
    • Timing and synchronization (frame/trigger)
    • Transceiver-to-compute data path (sample rates, formats, latency/throughput)
    • RF/antenna boundary
• Own and continuously evolve the system model — effectively a digital twin of the sensor. During the evolution:
  • Maintain ICDs
  • Meet and manage performance metrics
  • Grow model fidelity over time, introducing the non-idealities and non-linearities that matter as complexity increases (phase noise, PA compression, quantization, channel mismatch, mutual coupling), and trace observed behavior back to the origin.
• Collaborate with the DSP engineer on the waveform and detection design
  • You lead the strategy, they own the implementation and pressure-test it for compute load, memory, and timeline — until the architecture is both performant and buildable
• Converge the open architecture questions to decisions on a schedule
  • Committing with the evidence available, revisiting only when new data (a budget, a measurement) actually changes the answer

Required Qualifications

• Radar systems you’ve architected and shipped end-to-end — from waveform and detection through the RF chain
• Strong grounding in radar detection theory
  • FMCW/chirp waveforms, range-Doppler processing, CFAR and SNR/integration, and angle estimation
  • Target-tracking fluency to set the requirements (update rate, track accuracy)
• Hands-on MATLAB for system-level radar modeling (Radar Toolbox) — you’ve built and evolved system models, not just read their output
• Track record personally owning and closing the quantitative budgets 
  • Link and detection budgets above all — and holding the design to them
• RF chain architecture experience with multi-channel/MIMO transceivers and the coherence challenges of scaling channel count, from LO/clock distribution to phase alignment across the array
• Able to work independently on a contract basis
• Must pass company security procedures
• Must communicate effectively in English

Preferred / Bonus

• Counter-UAV or defense radar experience specifically — small, low-RCS, maneuvering targets in cluttered environments
• Hands-on experience with integrated radar transceiver SoCs including integration tradeoffs they bring
• MATLAB Simulink

Engagement Details

• Type: Contract-to-permanent position
  • Starts as a contract engagement with an explicit track to a permanent lead role for the right candidate
• Rate: [TBD]
• Duration: [TBD]
• Location: Remote/Hybrid
   
  • Hybrid: Must be able to temporary travel to Kyiv for on-site testing is heavily preferred (all expenses paid) — system bring-up and field validation against real targets, correlating measured performance against the model.

• Run discovery calls and qualify genuine pain around forecast reliability
• Qualify opportunities for both SalesGuard and consulting services across Microsoft Fabric, Power Platform, Azure, Dynamics 365 and Data & AI initiatives
• Manage opportunities through the full sales cycle alongside the founder, who handles product demonstrations, solution architecture, security reviews and technical discussions
• Build relationships with Microsoft partners, consulting firms and enterprise decision-makers
• Help secure the first reference customers that will support future Microsoft co-sell activities
• Provide honest and fact-based feedback about messaging, market response and pipeline quality

What we expect

• 5+ years B2B software sales, at least 2 in enterprise deals
• Experience selling into UK, US or other English-speaking markets; experience in DACH region is an advantage.
• Comfortable representing a company that is still building market presence and customer references
• Able to hold a credible conversation with technical evaluators
• High integrity and transparency in reporting
• Professional English (C1 or higher); Professional German is an advantage

Nice to Have

• Experience within the Microsoft ecosystem
• Familiarity with Dynamics 365, Power Platform, Microsoft Fabric, Azure or Power BI
• Background in CRM, Revenue Operations or Sales Operations environments
• Experience selling consulting services, implementation projects or managed services
• Experience with public tenders, partner-driven opportunities or Microsoft partner ecosystems
• Experience navigating procurement, legal review and enterprise security processes

What we offer

• Full remote
• Direct work with the founder, no layers
• Real ownership of the go-to-market motion
• Base plus uncapped commission on new business
• Contract as a freelancer (ФОП), with monthly invoicing in EUR
• We support you with the administrative side of freelancer registration and taxation
• Long-term role as we grow, not a short campaign

Honest expectations

This is early. There are no inbound leads, no marketing team, no reference logos. The first months are outbound and discovery. If you want a mature pipeline handed to you, this is not the role. If you want to build a category from zero, it is.

About the Role 

ONU Health is building the AI-powered future of personal prevention. We unify medical, lifestyle, and wearable data into a single "health account," helping people see risks before they arise and take control of their wellbeing.

We're seeking a co-founding Marketing Manager who can bridge storytelling, community, and growth — turning a preventive health mission into a movement. You'll work closely with our designers and CEO to define how ONU Health is communicated, build our community, and grow our customer base.

Key Responsibilities

🧭 Brand Strategy & Positioning

• Define ONU's brand narrative — "Your data, your health, your prevention."
• Position ONU between medical credibility and lifestyle inspiration — where prevention feels aspirational, not clinical.
• Shape a unified messaging architecture across web, app, and social, highlighting ONU's unique value: predictive, data-driven, and privacy-first.
• Work with designers and the CEO to establish ONU's visual and verbal identity across all channels.

📊 Social Media, Funnels & Campaigns

• Own social media strategy and content calendar — building ONU's presence and voice across key platforms.
• Design and run campaigns that build brand awareness and drive customer acquisition.
• Build and optimize multi-channel acquisition funnels (content, influencer partnerships, paid social, and Apple Health integrations).
• Develop onboarding journeys, email/push automations, and retention loops tied to users' health improvements.
• Track activation, retention, and referral metrics to continuously refine messaging and campaign performance.

💬 Community & Thought Leadership

• Create the ONU Health Founding Member Program and early adopter community.
• Grow and nurture ONU's customer list and community channels.
• Collaborate with medical advisors and creators to launch educational campaigns around prevention and self-tracking.
• Drive storytelling across channels (press, social, product updates) to humanize complex AI health concepts.

Requirements

• Experience in social media, brand, or growth marketing, ideally in digital health, fitness, or consumer SaaS.
• Proven experience building campaigns and funnels that grow an audience or customer base, ideally for an early-stage product.
• Strong understanding of healthtech positioning, user psychology, and trust building (especially for sensitive data products).
• Analytical and creative mindset — fluent in both storytelling and metrics (CAC, LTV, retention).
• Comfortable working closely with designers and founders to shape brand identity from the ground up.
• Passion for preventive health, data-driven wellness, and AI-enabled personalization.

Benefits

• Equity: based on experience and time commitment, as a co-founding role.
• Vesting: 4 years with 1-year cliff.
• From February: Future Salary Post-funding (March 2026).
• Equal say in product and roadmap decisions alongside founders.
• Flexible schedule (20–30 hrs/week possible; past funding to full-time).
• Remote-first (EU time zones preferred).

ONU Health is a HealthTech startup from Berlin. We're building a smart "health account" — a secure platform for storing and analyzing medical data: test results, diagnoses, medications, and personal health goals. Using AI, we provide personalized recommendations and help people better understand their health. We are not a medical product and do not provide diagnoses.

Our team already includes four people — developers, designers, and a project manager. We're a close-knit, ambitious team building the future of preventive health.

We're a US skincare brand. We sell through our own Shopify store and TikTok Shop, in the US and internationally. There's a second brand in the same space you'd also work on.

Small team, No layers, decisions happen the same day you ask.
 

The role in one sentence - You own what the brand says, and how well it sells.
 

What you'll do

• Write the copy. Product pages, landing pages, TikTok Shop listings, email sequences, video scripts and hooks. You write it - you don't brief a copywriter and wait.
• Own the message. Positioning, the mechanism story, the hook bank, and what we can and can't claim.
• Direct the vendors. Designer, video editor, photographer, email agency. You brief them and you approve the output.
• Find what's broken. Read reviews, survey buyers, watch session recordings, form a hypothesis, test it, write down what happened.
• Work on the offer. Bundles, kits, subscription, post-purchase upsells. Conversion rate is half the job; average order value and repeat purchase are the other half.
   

What we're looking for

• You've written copy for a consumer product that people actually bought. Physical product preferred. Send samples - this matters more than your CV.
• E-commerce background (Shopify, Amazon, TikTok Shop, or similar). This isn't a B2B or SaaS role.
• You can copywrite a landing page yourself.
• English strong enough to write for a US consumer (C1+). We'll ask for a short sample.
• You're fine being measured on numbers.

Nice to have

• Beauty, skincare, or personal care
• TikTok Shop
• You know direct-response marketing — Schwartz, awareness stages, offer structure, that world

This role does not include buying media. We're not asking you to run Meta or TikTok ads.

Process

Short call → paid test task (about 4 hours, we pay for it, most be not AI written) → offer. We won't drag you through five rounds.
