The company is building a healthcare-focused adtech platform that enables precise targeting of healthcare professionals using large-scale data and AI.

We’re looking for a Senior Data Analyst to define how we measure data quality, evaluate AI/LLM-based scoring, and generate insights that support product, sales, and media buying teams. You’ll work with 70+ TB of data, design evaluation frameworks from scratch, and help optimize performance, cost, and data pipelines.

Responsibilities

• Measurement & Evaluation Foundations: Define how we measure what matters — data quality, the accuracy of our AI scoring, how many records actually get matched to usable signals, cost per outcome. Build the feedback loops that tell us whether a change makes the system better or worse.

• Scoring Intelligence (co-owned with engineers): Partner with the engineering team on the LLM-based scoring system. You will build the evaluation framework for AI scoring, run experiments comparing prompts, models, and approaches against a baseline, and make data-backed calls on where we invest next. Our AI scoring system is actively evolving — you will shape how we measure and improve it.

• Client-related Analysis: Own the analytical side of the work that internal sales and media-buying teams bring in from pharma clients — how reachable a target audience is, how good the data looks, why a campaign performed the way it did. You turn their questions into data-backed answers they can use. Identity is a product core; the analyst works with internal teams, not with clients directly.

• Cost and Value Analysis: Turn cost and value into product decisions. Which data sources and enrichment scenarios pay off, where we overspend, what to cache, what to cut. We operate a mix of free owned data and paid external providers — the decisions have real dollar impact.

• Active AI Usage: Use Claude Code and modern AI engineering tools to multiply your own output. Automate the repetitive parts of analysis so you can focus on the decisions. We provide Claude Code licenses and expect active daily use.

• Data Quality Response: When pipeline output drifts, a provider degrades, or upstream data shifts, you notice first, diagnose the root cause, and drive the fix. You treat data quality as a product, not a ticket queue.

Requirements

• 5+ years as a Data Analyst, Analytics Engineer, or Data Scientist in a product team (not consultancy, not BI-only roles).
• Advanced SQL at TB scale — BigQuery, Snowflake, or equivalent warehouse. You can read and write complex queries on tens of terabytes without someone pre-modelling the data for you.
• Python for analysis at a working level — pandas, Jupyter, or modern equivalents. Comfortable putting together a small script or helper when an existing tool doesn't cover your case.
• Built measurement or evaluation frameworks from scratch for systems that had no baseline. You are comfortable defining what and how to measure, not consuming someone else's KPI.
• Comfort with probabilistic systems. You understand that noise is inherent and 100% accuracy is not the goal — scoring, matching, ranking.
• AI-native workflow. You already use Claude Code, ChatGPT, Copilot, or similar AI tools daily and integrate them into your analytical process.
• English: B2+ (Upper-Intermediate) or higher.

Strong plus (one or more)

• LLM evaluation experience — A/B testing AI-powered features, output scoring, prompt iteration with measurable outcomes.
• Identity resolution / identity graph experience — adtech, martech, or customer data platform context (LiveIntent, LiveRamp, Epsilon, Experian Marketing, Acxiom, Merkle, or similar).
• Healthcare or pharma data — working with NPI, HCP-level data, healthcare taxonomies, pharma targeting.

Nice to have

• Experience running controlled experiments on data pipelines.
• Prompt engineering or structured LLM prompt design.
• Prior work in AI-first product companies.

Level: Senior (individual contributor)· 

Focus: Full-stack hardware + flight stack integration (ArduPilot / Betaflight) 

Location: On-site (lab / hangar)

About the role

We're looking for an experienced hardware engineer to own end-to-end flight-control hardware integration across a diverse fleet of drones — from FPV quads to larger autonomous multirotor, fixed-wing, and VTOL platforms. You'll be the person who takes a new airframe from a pile of components to a tuned, flight-ready system: selecting and wiring the flight controller, flashing and configuring ArduPilot or Betaflight, integrating ESCs, sensors, radios, power, and payloads, and tuning it until it flies cleanly.

This is a hands-on, on-site role based in our lab/hangar, spanning the full range from quick R&D prototypes to repeatable production builds. You'll be the hardware integration expert for the team, working independently and setting the standard for how builds are configured, documented, and validated. Success looks like new platforms reaching reliable, flight-ready status quickly — and builds that stay consistent and reproducible from one unit to the next.

What you'll do

• Own end-to-end hardware integration of flight-control systems across multiple platform types (multirotor, fixed-wing, VTOL, FPV).
• Select, flash, configure, and tune ArduPilot (Copter / Plane / Rover) and Betaflight; build and maintain custom firmware targets and board definitions where needed.
• Integrate and validate flight controllers, ESCs, and motors — including protocol setup (DShot / bidirectional DShot, PWM / OneShot), motor–prop matching, and thrust testing.
• Bring up and calibrate full sensor suites: IMUs, barometers, compasses/magnetometers, GPS/RTK, rangefinders, optical flow, and airspeed sensors.
• Integrate RC and telemetry links (ExpressLRS, TBS Crossfire, CRSF / SBUS, MAVLink, SiK radios) and FPV/video systems (analog and digital VTX, OSD, cameras, antennas).
• Spec, assemble, and wire power systems — distribution, regulation, current/voltage sensing, and battery selection — with clean, reliable harnesses.
• Integrate smart peripherals over CAN / DroneCAN and companion computers (Raspberry Pi / Jetson) over MAVLink.
• Diagnose vibration, noise, and EMI issues and implement fixes (soft-mounting, gyro/notch filtering, grounding, shielding).
• Run bench, ground, and flight tests; analyze logs (Mission Planner / MAVExplorer, Betaflight Blackbox) and iterate on PID and filter tuning.
• Root-cause failures and design for reliability — diagnose in-flight and bench anomalies, build in redundancy where it matters, and harden platforms to hold up in real-world field conditions.
• Take platforms from quick R&D prototypes through to repeatable, well-documented production builds — locking in configurations and processes that stay consistent across units.
• Document build configurations, wiring, and setup procedures, and support/upskill the team so they can operate and iterate independently.

• Work closely with the software, mechanical, and flight-test teams to integrate cleanly and resolve hardware–software issues together.

   

What we're looking for

• Hands-on experience integrating and configuring ArduPilot and/or Betaflight on real hardware.
• Strong working knowledge of drone subsystems: flight controllers, ESCs, motors, sensors, RC links, power, and FPV.
• Comfortable with soldering, wiring, and general benchtop debugging (multimeter, bench power supply).
• Solid grasp of the relevant protocols: DShot, CRSF / SBUS, MAVLink, I2C / SPI / UART, and ideally CAN / DroneCAN.
• Experience tuning multirotor and/or fixed-wing platforms and reading flight logs to track down problems.
• Able to work independently and own a hardware domain from first component to flight-ready system.
• Comfortable switching between fast prototype iteration and the repeatability that production builds demand.
• Typically 4+ years in drone/UAV hardware, robotics, or embedded systems.

• Degree in electrical, aerospace, mechatronics, or robotics engineering — or equivalent hands-on experience.

   

Nice to have

• Writing custom ArduPilot board definitions (hwdef) or Betaflight targets, and compiling firmware from source.
• Familiarity with PCB design (KiCad / Altium) is a welcome bonus — but we treat full board design as a separate specialty, so it's not expected for this role.
• RTK GPS and precision navigation, lidar, or computer-vision payload integration.
• Breadth across airframe types — VTOL, large industrial, or agricultural platforms.
• Familiarity with the drone and aviation regulations that apply in the role's region.
• Comfortable with 3D printing and rapid prototyping for custom mounts, frames, and fixtures.

Tools & technologies you'll work with

• Firmware / stacks: ArduPilot, Betaflight
• Flight controllers: Pixhawk / Cube, Holybro, Matek, SpeedyBee, Kakute (STM32 F4 / F7 / H7)
• Ground stations: Mission Planner, QGroundControl, Betaflight Configurator
• Protocols: MAVLink, DShot, CRSF, SBUS, DroneCAN / CAN, I2C / SPI / UART
• RC / telemetry: ExpressLRS, TBS Crossfire, SiK radios
• ESC firmware: common ESC firmware and configuration tools
• Bench: Soldering station, multimeter, bench power supply

What we offer

• Competitive salary, set to experience
• A fully equipped lab and a budget for the gear, tools, and parts you need
• Health coverage, paid time off, and the standard benefits
• Room to grow your skills and shape how the team builds

Full compensation details are shared early in the process.

About us

We design and build drones across a range of platforms and applications, and we care about getting the hardware right. You'd be joining a hands-on team that puts real aircraft in the air and values engineers who can own their work from the bench to the flight line.

How to apply

To apply, send your resume along with anything that shows your work — builds you've integrated, logs or tuning you're proud of, repos, or flight videos. We'd love to see what you've put in the air.

Duck Agency – we automate operations, sales, and marketing for businesses, and build custom software on top of that. Our clients don't want cookie-cutter fixes, they want stuff that actually moves the needle.

Who we're after

Someone with fire in their eyes. Not the "just tell me what to do" type – we want someone who shows up with ideas, tests them, and pushes for more. If you'd rather wait for a brief than write one, this probably isn't your gig.

What you'll actually be doing

• Coming up with lead-gen hypotheses and testing them out – working closely with the CEO and leadgen
• Hunting down and talking to potential partners
• Reaching out to and closing clients across different industries
• Building your own playbook instead of running someone else's script

What we need from you

• Real sales experience (doesn't have to be years and years, just real)
• You actually get IT – how dev works, what "process," "system," and "integration" mean in practice. You need to talk to clients like you know what they're building
• Proactive by nature – bring ideas, take initiative, be okay with some of them not working

The setup

• 100% remote
• Flexible hours – we care about output, not clock-watching
• Direct line to the CEO, direct influence on how we sell and position ourselves
• Your ideas get used, not filed away

If "here's what I think we should try" is more your style than "waiting for instructions" – let's talk
