Sounds like a fit? We'd love to hear from you!

Nobody taught our generation how money works.

We earn, we spend, we mean to save  and somehow the year ends the way it started. Financial literacy is the one thing nobody teaches you, and the one thing everyone assumes you already have.

GRO is an AI powered financial companion for exactly those people: Gen Z and Millennials that teaches you money instead of just tracking it.

https://www.joingro.com/

Our mission is to teach the next generation what nobody taught ours.

Our stage: Pre-seed closed, public beta and launch before the end of this year. 

WHO YOU'D BE JOINING

Four founders. 

Our CTO is building the Companion - the LLM layer, the memory, the architecture intent.  You'd be the person who turns it into something people can actually hold: the app, the backend, the money layer, the release pipeline.

First engineer in, which means you're not inheriting anyone else's decisions. You're making them. Hands-on all the way through beta  and if you want to grow into leading the team you help hire, that path is open and it's yours to take.

First six months: a native app live on both stores, a backend that's secure and observable, and a release process the team can run without you in the room. Then: open banking integration, SOC 2 groundwork, and the kind of engineering a Series A technical diligence doesn't flinch at.

WHAT'S YOURS

— The app. React Native / Expo. Performance, offline behaviour, native builds, OTA.

— Store releases. App Store and Google Play, signing through post-launch.

— Backend and the money layer. NestJS, Prisma, Postgres, OpenAPI. Idempotency, audit trail, tenant isolation.

— Platform, security and compliance. Shared with the CTO, executed by you — CI/CD, IaC, secrets, observability, GDPR, SOC 2 path, QCB readiness.

— The boundaries that matter. The deterministic money core and the education-not-advice line, enforced in code rather than in disclaimers.

WHO WE'RE LOOKING FOR

— You've shipped and operated a consumer financial product. Real users, real money, real incidents.

— Your React Native or Expo apps are live on both stores, and you handled signing, review and everything after launch.

— Node and TypeScript backend depth is real - NestJS or equivalent, Postgres, contract-driven.

— CI/CD, Terraform, secrets and observability are just how you work. Not a task you get to later.

— Security-first by instinct: auth hardening, idempotency, audit trails, PII, threat modelling.

— You're comfortable with a clean line: the CTO owns the Companion and the architecture intent, you own everything around it. That takes trust in both directions.

— English C1 or above. It's our working language.

NICE, NOT REQUIRED

Open banking aggregators (Tarabut, Plaid or similar) - a dedicated expert owns that bridge, you'd partner with them. SOC 2 or ISO 27001 audits. Cost and eval discipline for LLM-powered apps.

THE SETUP

Remote. Full-time. A path to founding team member, working directly with the CTO. Compensation and equity could be discussed directly.

We're small enough that you'll know why every decision got made, and early enough that a part of them will be yours.

T H E  R O L E
Own the intelligence layer of Rx360 — the models that turn continuous sensor and medication data into a working understanding of each individual we serve, and turn that understanding into actions that help them stay independent. You will set the ML architecture, build the longitudinal modeling stack from raw signal through to user-facing recommendation, and define how our models and our conversational companion work together.

W H AT Y O U ' L L D O
Own the ML architecture for personalized health intelligence — per-user baselines, N-of-1 and hierarchical models, and the strategy for learning from one individual's history rather than a population mean.
Build the digital biomarker stack on raw wearable signal: gait and cadence, sit-to-stand and postural transitions, activity classification, sleep and circadian structure, and cardiovascular trend from IMU and PPG streams.
Design change detection and event-association models that link medication starts, dose adjustments, and adherence gaps to downstream behavioral shifts — with defensible handling of confounding, lag structure, and multiple comparisons.
Turn a detected change into a recommendation: what to surface, to whom (the individual, family, pharmacist, or provider), with what urgency — and when the right answer is to say nothing.
Build the data and training infrastructure that carries high-frequency time-series from device ingestion through feature generation, training, serving, and monitoring.
Own evaluation. Offline benchmarks, labeled ground truth from pilot cohorts, calibration and drift monitoring, and the false-positive budget that decides whether people trust what we tell them.
Ground our conversational companion in real signal. Our AI companion runs on a large language model inside our
HIPAA-compliant cloud environment; you will connect it to per-user model output and own the evaluation and post- training work that keeps its guidance accurate, useful, and safe.
Push inference to the edge where latency, privacy, or battery demand it, working directly with the firmware and hardware teams on what runs on the band versus in the cloud.
Direct AI coding agents to accelerate implementation while holding a rigorous quality bar — the way the rest of our engineering team works.
Partner with clinical collaborators, including our university pilot, to design studies that produce the labeled data these models actually need.
Set technical direction and raise the bar for ML across the team.

R E Q U I R E D
6+ years in machine learning, including systems you have shipped to real users and operated in production — not only research or prototypes.
Deep experience with time-series or sensor data: physiological signals, IMU / accelerometry, or comparable high- frequency multivariate streams.
Demonstrated work in individual-level modeling — per-subject baselines, hierarchical or Bayesian methods, anomaly and change-point detection, or models that adapt as data from a single person accumulates.
Strong applied statistical judgment. You can separate a real effect from a coincidence in observational data, and you know exactly where a causal claim stops being defensible.
Production-grade Python and PyTorch (or equivalent). You write software other engineers are willing to maintain.
Ownership of the full lifecycle: data pipelines, training infrastructure, deployment, monitoring, and retraining.
Experience with large-language-model evaluation and post-training — grounding and retrieval, structured output, eval harnesses, and guardrails.
Cloud-native ML at production scale (AWS preferred).
Fluent use of AI development tools (Claude Code, Cursor, Copilot, or equivalent) with the domain depth to catch where generated code fails silently.
Clear, direct communication. You can set direction across firmware, backend, mobile, design, and clinical stakeholders.

N I C E T O H AV E
Wearables, digital biomarkers, gait analysis, fall risk, or human activity recognition.
Self-supervised or foundation-model approaches for wearable time series, and comfort working under real label scarcity.
Causal inference on observational data — interrupted time series, difference-in-differences, or synthetic control.
Medication-effect modeling: polypharmacy, adherence, or PK/PD intuition.
On-device and edge ML — quantization, distillation, TinyML, inference under a power budget.
Regulated environments: HIPAA and PHI handling, model governance, or the general-wellness boundary.
Clinical research collaboration and IRB-governed data.
Voice or audio ML.

W H Y T H I S R O L E I S D I F F E R E N T
G R E E N F I E L D
You are defining the intelligence layer, not maintaining someone
else's. The architecture decisions are yours to make.
R E A L S I G N A L
Continuous, longitudinal, multi- stream data from a device we build
ourselves — with the firmware team a message away.
I T M AT T E R S
A model that catches a medication effect three days early changes
whether someone keeps living in their own home.

H O W W E W O R K
Mission comes first.
The work has real impact on people's lives. We take that
responsibility seriously.
Thoughtful technology.
Technology should simplify life, not complicate it.
Respect for independence.
The people we build for value autonomy and dignity.
Everything we create reflects that.
Curiosity.
We encourage questions, experimentation, and new ways
of thinking.

• Product discovery based on player behavior, transaction data, game performance, market research, and competitor analysis.
• Core casino metrics: GGR, NGR, conversion, retention, churn, ARPU, LTV, reactivation, and bonus efficiency.
• Understanding different player segments and identifying what drives deposits, engagement, retention, and monetization.
• A/B testing and product experiments — from hypothesis to measurable business results.
• Collaboration with Retention and VIP teams to increase repeat deposits and long-term player value.
• Optimization of crypto payments, wallets, multi-currency flows, and related user experiences.
• Analysis of revenue and profitability drivers, including bonuses, payment fees, provider costs, and chargebacks.
• Translation of business goals and product insights into clear priorities for Product Owner and cross-functional teams.
•  

✅ What we’re looking for

• 4+ years of Product Management experience in iGaming.
• Proven hands-on experience with crypto casino products — this is important for the role.
• Strong understanding of casino mechanics: slots, live casino, bonuses, player lifecycle, retention, and reactivation.
• Experience owning product and business KPIs rather than simply delivering features.
• Strong analytical mindset and confidence working with funnels, cohorts, experiments, and product/business metrics.
• Ability to independently identify opportunities, build hypotheses, prioritize them, and measure the impact.
• Strong understanding of UX and experience optimizing high-impact player journeys.
• SQL knowledge or hands-on experience working directly with analytics and back-office data.
• Comfortable working with a high level of ownership, autonomy, and fast decision-making.
•  

🧠 The mindset we value

We’re looking for someone who thinks “What will move the metric?” rather than “What feature should we build next?”

You’re curious about why players behave the way they do, comfortable challenging assumptions, and able to change direction when the data tells a different story.

You move fast, test hypotheses, measure results, and iterate.
