Our team works across hardware, firmware, software and AI. We move quickly, care deeply about the people we build for, and hold a high bar for quality and trust.
We're looking for a Data Scientist to turn what our wearable senses into intelligence that keeps seniors safe. You'll build the machine learning behind fall detection and fall-risk prediction, and the health and activity insights our AI companion shares with seniors and their supporters. You'll own models from raw sensor data and labels through validation and deployment, on the band and in the cloud.

What You Will Do
• Build and own ML models for fall detection on the Rx360 band, using IMU, barometer and PPG signals, with high sensitivity and very few false alarms
• Develop fall-risk and fall-prevention models that spot changes in gait, activity, sleep and heart rate over days and weeks, so supporters can act before a fall happens
• Build our datasets from real-world wear by older adults, including data collection, labeling and ground-truth processes with pilot and clinical partners
• Design validation plans and success metrics, such as sensitivity, false alarms per wearer-day and time to alert, and run validation studies in pilots
• Work with firmware engineers to run models on the band within tight memory, compute and battery limits, through feature design, model compression and quantization
• Define the sensor data we capture and how it flows from band to cloud, and build the pipelines and tooling that keep it clean, labeled and usable for training
• Turn sensor data into everyday insights, such as steps, activity, sleep, heart rate trends, wear time and anomalies, for our AI companion and supporter app
• Monitor model performance in the field, investigate misses and false alarms, and retrain and improve models over time
• Partner with product, hardware, firmware, software, clinical and AI teams to shape requirements and decide what to build next
• Handle health data responsibly, with privacy, consent and security built into how we collect, store and use it
• Communicate results, trade-offs and risks clearly to technical and non-technical colleagues

What You'll Bring
• 5+ years of experience in data science or machine learning, including models shipped to production

• Required: at least 2 hours of overlap each day with U.S. Central time (CT) working hours to collaborate with our U.S. team
• Hands-on experience with time-series sensor data, such as accelerometer, gyroscope or PPG, including signal processing and feature engineering
• Strong Python and experience with deep learning frameworks such as PyTorch or TensorFlow, along with classical ML methods
• Experience with rare-event problems and imbalanced data, and sound judgment on evaluation, error analysis and the cost of false alarms versus misses
• Experience deploying models to resource-constrained or embedded devices, or working closely with firmware engineers to do so
• Experience designing data collection and labeling, and building data pipelines (SQL, cloud data tools)
• Excellent written and spoken English
• Comfort working remotely and asynchronously across time zones

  let`s talk.

Our product is a B2B iGaming platform that enables clients to launch online casinos under our license (white-label) or their own (turnkey). It covers everything an operator needs: PAM and wallet, cashier and payment integrations, KYC/AML and responsible gaming, bonuses and CRM, game content, sportsbook (typically third-party), frontend and CMS, affiliate system, back office, and reporting. Product and engineering teams are already in place. Alongside the platform, we run our own game aggregator supplying content to both our platform and external casinos. We’re looking for a Product Owner to take ownership of both products—driving the platform vision, shaping aggregator growth, and aligning roadmaps across teams.

Responsibilities

• Audit the current state of the platform and aggregator (modules, packages, target segments), define the target product vision and path to get there, and align engineering, sales, and leadership around a single picture
• Define the value proposition: target customers (new operators, existing brands, migrations from other platforms), target markets, and clear differentiation from SOFTSWISS, EveryMatrix, BetConstruct, and others
• Own product packaging, pricing models (setup fees, revenue share, modules), and discount corridors, proposing and aligning them with leadership
• Make build-vs.-partner decisions across modules (sportsbook, KYC, payment providers), manage the roadmap, and set priorities for development teams
• Own the end-to-end client journey from contract signing to a live casino: onboarding, configuration, and launch timelines
• Own the game aggregator as a product: value proposition for external casinos, provider integration priorities, and a unified roadmap with the platform
• Validate the offering in the market through customer interviews, pilots, and joining the first 5–10 deals as product lead alongside sales
• Deliver key outcomes in the first 90 days: a breakdown of the current product, a target vision for the platform and aggregator, a competitive gap analysis against market leaders, and a 2–3 quarter roadmap signed off with the teams.

Requirements

• Hands-on experience launching or scaling a B2B casino platform (white-label, turnkey, or PAM) with paying operators
• Strong understanding of operator and platform economics: GGR, NGR, bonus costs, payment fees, and revenue share
• Product-level expertise in core platform modules: PAM and wallet, cashier, KYC/AML and responsible gaming, bonuses and CRM, and aggregator content delivery
• Solid grasp of how a game aggregator works: provider integrations, commercial terms, and external casino clients
• Clear understanding of launching a casino in different jurisdictions and the operational differences between white-label and turnkey models
• Ability to formulate a value proposition from scratch, test it with clients, and enter the market without relying on a pre-existing network
• Strong execution skills: writing PRDs, setting clear requirements for engineering teams, and tracking product metrics
• Fluent English.
