About the role

This isn’t a typical corporate PM role with pre-defined processes and reporting layers — you’ll be the person who brings clarity where there’s ambiguity, and structure where there’s chaos.
You’ll work closely with strong, autonomous Product and Customer Success teams to help them stay focused, communicate effectively, and deliver impact — while building trust with stakeholders and clients along the way.
 

What makes this role unique/Challenges

• Balancing Client Expectations with Technical Realities. Clients often want a lot—and fast. Your challenge is to set realistic expectations, negotiate priorities, and help both sides (client and dev team) stay aligned
• Managing Ambiguity Client needs might be vague or evolving. You’ll need to translate unclear feedback into actionable insights without derailing timelines
• End-to-End Visibility You’ll oversee the entire product lifecycle—from gathering initial feedback to ensuring smooth, bug-free releases. Your role directly impacts the client experience and product quality
• Tight Feedback Loops This is not a slow-moving corporate setup. You’ll be part of a nimble team where decisions are made fast, iterations are frequent, and your input is valued from day one

What you’ll be doing

• Act as the main point of contact between clients/stakeholders and the development team
• Collect, evaluate, and clearly communicate client feedback and requirements
• Plan and manage the entire development cycle—from a ready MVP to a full release and further product support
• Ensure timely, high-quality, and bug-free releases
• Set clear deadlines and communicate realistic timelines to clients
• Align internal and external expectations to avoid surprises and delays
• Participate in both client-facing and internal team meetings

What we’re looking for

• Experience as a Project Manager for 4+ years.
• Experience working with international B2B SaaS teams or MarTech products.
• Experience working with enterprise customers. 
• Excellent communication and stakeholder management skills — both inside and outside the team.
• Fluency in English — all interviews and client-facing communication are in English.
• Data driver approach.
• Ability to explain complex ideas simply and clearly — especially to non-technical audiences.
• Confident, calm presence under pressure — you bring order, not noise.
• Strong facilitation skills — you lead with structure, not authority.
• A proactive mindset — you see problems before they grow and solve them collaboratively.

• Location - Kyiv.

   

What we offer

• The dream team of passionate people and strong internal culture
• Opportunity to work on a cutting-edge product used by global brands
• Professional growth in a collaborative and innovative environment full of professionals
• Competitive compensation and benefits package
• We will pay for your professional development ─ conferences, courses, books, etc.
• Flexible schedule
• Medical insurance
• 4-day workweek during summer
• Unlimited vacations (yes, really)

How the recruitment process goes:

1. Interview with Head of TA
2. Interview with Hiring Managers ~1 hour
3. Test task
4. Recommendation check

c3 is a research-led startup based in London and Kyiv. We are expanding our team and research and are seeking an RF engineer as part of this expansion. 

Requirements

• Strong background in RF sensing and wireless signal processing: channel state information (CSI), RSSI, multi-carrier/OFDM systems, amplitude/phase extraction, multipath, and the physics of RF propagation.
• Hands-on experience with real RF/wireless hardware data. You should have dealt with noisy channel estimates, phase instability, hardware/carrier frequency offsets, antenna effects, calibration drift, and the gap between clean lab captures and messy real-world signals.
• Strong understanding of RF signal-to-information inversion: extracting physical meaning from raw wireless measurements, and reasoning rigorously about what is and isn't recoverable from a given signal.
• Experience solving temporal sensing problems: detecting sustained change in a physical environment against a learned baseline, and separating genuine events from transient or cyclical confounders.
• Familiarity with the electromagnetic behaviour of materials (attenuation, permittivity, frequency-dependent effects, multi-band sensing) is highly valuable.
• Strong Python and PyTorch skills, with experience building production-quality evaluation and inference pipelines.
• Experience with classical estimation alongside ML — Kalman/particle filtering, Bayesian inference, change-point detection, or equivalent — not only deep learning.
• Experience with signal-processing toolchains (NumPy/SciPy, spectral analysis, filtering) and, ideally, embedded RF platforms (ESP32, SDR, Nordic, or similar).
• Experience with synthetic data generation / physical simulation for augmentation and controlled failure-case generation.
• WiFi sensing, radar, RF localization, IoT sensing, wireless communications, or defence signals experience is highly relevant.
• Fluent English.
• Kyiv-based preferred; hybrid or remote considered.

What you will do

• Build robust detection pipelines that extract a reliable physical signal from cross-link RF data while remaining insensitive to everyday environmental variation.
• Handle noisy channel estimates, phase drift, packet loss, hardware offsets, and differences between devices and deployments.
• Build temporal detection and classification that distinguishes genuine sustained events from transient activity, environment-wide confounders, and cases of insufficient evidence.
• Develop confounder-rejection reasoning so that environment-wide effects are not misclassified as localized events.
• Build multi-band and cross-link inversion using physical models and learned features, followed by robust localization.
• Define confidence / failure detection for detection and localization results rather than forcing a result from bad signals.
• Develop event classification and severity scoring once the underlying signal is sufficiently reliable.
• Create synthetic perturbations and physics-based generated training/evaluation data covering known failure modes.
• Own evaluation against ground truth, including detection rate, false-positive/negative rate per unit-time, localization accuracy, timing error, and uncertainty calibration.
• Evaluate alternative sensing representations and fusion approaches — including multi-band spectral methods, time-of-flight techniques, and integration with external contextual data — where they materially improve fidelity.
