We are Leaply, an ecosystem of digital and physical products designed to help people build healthy habits and improve their quality of life. We operate in global markets - the US, Tier 1, Europe, and beyond.

In June 2024, we launched an app focused on habit-building, using a subscription-based monetization model and a performance-first marketing approach (Meta, Google, TikTok). Within the first two months, we achieved positive unit economics and are now on track to grow 10x by the end of the year.

Our team is building its third business together, with successful exits behind us and a deep understanding of our niche and target audience. We move fast, communicate openly, and set ambitious goals.

— Develop and maintain production-grade integrations with Meta / TikTok / Google — ensuring robust error handling, rate limiting, retries, and clear monitoring so the system operates reliably without silent failures;

— Redesign the tracking architecture by shifting from client-side to server-side (CAPI pattern for Facebook and similar platforms), implement proper test coverage, and build tools that allow Growth Managers to independently configure tracking for their funnels;

— Eliminate manual operational workflows (e.g., in Airtable) and enable marketing teams (UA managers, designers, growth managers) to operate independently without engineering support for routine tasks;

— Proactively identify and implement new martech solutions before they become bottlenecks - shaping the long-term vision of the domain and driving technical and product priorities.

— Ability to collaborate with non-technical stakeholders — UA managers, designers, growth managers;

— Ownership mindset — proactively identifies risks, drives solutions, and thinks in terms of business impact;

— Uses AI as part of their workflow to move faster and think broader.

Nice-to-have

— Experience with Meta Business SDK / TikTok Marketing API / Google Ads API;

— Understanding of performance marketing — ROAS, CAPI, pixels, attribution;

— Experience building server-side tracking (e.g., Facebook CAPI or similar);

— Internal clubs by professional areas: marketing, development, finance, recruiting, brand ambassadorship;
— Trainings, courses, attending conferences;
— Health insurance.

We are looking for a Senior Data Analyst to join our global team. This is not a standard analyst role. We are building a dynamic identity resolution system where AI is deeply integrated — both as a productivity multiplier and as a core component of our data processing logic for identity resolution and LLM-based scoring.

We run enrichment against 70+ TB of data, apply AI and LLM-based scoring on top, and process around 20 million enrichment operations per day across hundreds of thousands of records.

The analytical challenges ahead are substantial: how to measure the quality of AI-driven scoring, how to validate that a change makes the system better, how to know where our money and time deliver the most value, and how to turn the questions our internal teams bring in into fast data-backed answers. You will own this side of the business, working daily alongside engineers and the product lead to turn these challenges into decisions that ship.

The main part of the role is not building dashboards — it is the data work that makes a meaningful dashboard possible in the first place.

 Concretely, you will be:

• Looking at data from multiple vendors side by side and deciding what to trust.
• Reconciling entities across sources that have different shapes and quality.
• Proposing and validating the logic that matches and scores them.
• Defining metrics and ground truth for questions nobody has asked before.
• Tracing why numbers don't line up across partial and sometimes contradictory sources.
  
  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.

Culture & Mindset

• Self-improvement: You are a fast learner. You don't fear AI replacing you; you master it to replace your manual tasks.
• Ownership: You treat the Identity domain as your own business. If scoring quality drifts or a provider degrades, you notice it and drive the fix without being asked.
• Internal Locus of Control: You take responsibility for outcomes. If external data shifts or an API changes, you build around it instead of blaming the provider.
• Get It Done: You prioritize shipping answers. You know when to send a rough estimate and when to build a proper framework.

Openness: You share findings and admit mistakes openly — both wins and failures travel across the team. If you spot a better way to do something, you volunteer it without being asked.

What You'll Own

• Architecture & technical direction of the entire serverless backend (Google Cloud Functions on Firebase / GCP).
• Code quality and standards — review PRs, define patterns, and guide the team on TypeScript best practices.
• System reliability — performance, observability, error handling, and deployment safety across dev / pre-prod / production environments.
• Integration strategy — design and maintain reliable two-way data flows with NetSuite, Business Central, HubSpot, Mailchimp, Constant Contact, Stripe, HERE API, Zapier, and Integration.app.
• Data architecture across Firestore (primary operational DB) and MongoDB (data warehouse).
• CI/CD pipelines in GitHub Actions, including selective function deployment.

• Mentorship — grow the engineering team and raise the bar on code review, testing, and documentation.
  
  What We're Looking For

  Must have:

• 8+ years of backend development with Node.js and TypeScript in production environments.
• Strong experience with serverless architectures — ideally Google Cloud Functions, AWS Lambda, or equivalent.
• Hands-on experience with NoSQL databases (Firestore, MongoDB, DynamoDB, or similar).
• Proven track record designing and maintaining third-party integrations (ERP, CRM, payment processors, webhooks).
• Solid understanding of event-driven architecture (Pub/Sub, queues, scheduled jobs, triggers).
• Experience designing REST APIs, request validation, authentication, and authorization patterns.
• Comfort owning CI/CD pipelines and managing multi-environment deployments.

• Ability to communicate clearly with non-technical stakeholders — including project managers, founders, and customers.

   

   

  Nice to have:

• Experience with Firebase ecosystem (Firestore, Cloud Functions, Auth, Storage).
• Background in CRM, ERP, or field operations domains.
• Familiarity with Stripe billing, subscription lifecycles, and in-app purchase reconciliation.
• Experience with geospatial features (route optimization, geofencing, HERE / Google Maps).

• Prior role as a tech lead or backend architect for an SMB / mid-market SaaS product.

   

  Why Join Us

• High ownership — you'll be the backend authority, not one of many.
• Real business impact — your work directly affects how field sales teams operate every day.
• Modern stack — TypeScript, serverless, cleanly structured codebase.
• Stable product with active enterprise customers and a clear product roadmap.
• Remote-first team and flexible schedule.
