The Opportunity
We are developing a suite of radar products that operates in the Ultra-Wideband (UWB) frequency band, and we need a senior RF engineer who can own the RF design from concept through production. This is a hands-on, full-lifecycle role - you will design, simulate, prototype, and validate RF circuits while simultaneously optimizing for real-world performance and manufacturable cost. You will work closely with embedded software, mechanical, and product teams, and your decisions will directly shape what ships. This is not a role for someone who wants to hand off to layout or fab; we need someone who sees the whole problem.

What You’ll Do
RF Circuit Design & Development

• Lead the RF circuit design for our UWB radar product, from architecture definition through schematic capture and layout review.

• Select and evaluate RF components — antennas, LNAs, mixers, filters, VCOs, power amplifiers — balancing performance, availability, and unit cost.

• Design RF front-end circuits optimized for target signal characteristics.

• Define and own the antenna design or selection strategy, including near-field and far-field characterization.

• Create PCB layout to ensure signal integrity.

Simulation, Prototyping & Validation

• Perform RF system-level link budget analysis and circuit-level simulation using industry-standard tools (ADS, HFSS, CST, or equivalent with HFSS preferred).

• Build and validate prototypes; own the bring-up and debug process from first power-on through functional verification.

• Develop and execute RF test plans covering S-parameters, noise figure, gain, linearity, spurious emissions, and phase noise.

• Use RF lab equipment proficiently: VNAs, spectrum analyzers, signal generators, oscilloscopes, and anechoic chamber setups.

• Identify root causes of RF performance issues and drive design-of-experiments to resolve them.

Cost Optimization & Manufacturing Readiness

• Drive cost reduction throughout the design cycle — component selection, BOM rationalization, and design-for-manufacturability (DFM) decisions.

• Partner with supply chain and contract manufacturing teams to ensure RF designs are producible at volume with acceptable yield.

• Define RF test fixtures and production test strategies that balance coverage with throughput and cost.

• Manage RF component approved vendor lists (AVLs) and qualification processes.

Compliance & Standards

• Navigate FCC Part 15 UWB rules and international equivalents (ETSI EN 302 065); support pre-compliance and accredited lab testing.

• Work with certification bodies and test labs to achieve regulatory approval efficiently.

• Ensure designs meet applicable RF safety and emissions standards.

 
What We’re Looking For
Required Experience

• 5+ years of hands-on RF circuit design experience, with a strong preference for candidates with 10 or more years.

• Demonstrated experience designing RF systems in the GHz range; UWB (3.1–10.6 GHz), radar, or pulse-based system experience is a significant plus.

• Proficiency in RF simulation tools (ADS, HFSS, CST, Sonnet, or equivalent) and schematic/layout tools (Altium, Cadence, or equivalent).

• Deep familiarity with RF test and measurement equipment and methodology.

• Track record of taking RF designs from concept through production, including regulatory certification.

Technical Depth

• Strong fundamentals in RF and microwave theory: transmission lines, matching networks, S-parameters, noise, and nonlinear device behavior.

• Experience with antenna design or antenna selection.

• Solid understanding of PCB design for RF.

• Familiarity with UWB waveforms and the regulatory constraints unique to UWB operation.

• Ability to read and author detailed RF specifications and test plans.

Startup DNA

• Comfortable owning problems end-to-end without a large support structure around you.

• Pragmatic about tradeoffs — you know when 90% of theoretical performance at 60% of the cost is the right answer.

• Strong communicator who can explain RF constraints and tradeoffs to non-RF engineers and cross-functional stakeholders.  This role will work collaboratively with Resolv’s entire engineering team.

• Self-directed; you can set your own agenda, manage your schedule, and escalate the right things at the right time.

 
Nice to Have

• Prior experience with UWB ranging, radar, or FMCW/IR-UWB radar architectures.

• Familiarity with chipsets from Qorvo, NXP, Decawave (Qorvo), Novelda, or similar UWB/radar IC vendors.

• Background in signal processing or DSP relevant to radar (range-Doppler, CFAR, clutter rejection).

• Experience with MEMS sensors or sensor fusion in hardware products.

• Knowledge of IEEE 802.15.4a/4z UWB standards.

• Experience with hand-held or battery-powered product constraints (power budgets, thermal, packaging).

 
Compensation & Benefits

We offer a package built for someone who wants to build something real, not just collect a paycheck:

• Base salary that is intentionally below market — we are a startup and we are transparent about that tradeoff.

• Equity that reflects a senior technical contribution: your grant will be sized to recognize that specialized RF expertise at this stage is genuinely company-enabling.

• Full health and dental coverage.

• Flexible PTO and a culture that actually respects it.

• A well-equipped RF lab — we will invest in the tools you need to do the job right.

• The chance to define the RF architecture of a new product category, with full ownership and visibility.
