We are looking for a Senior Data Analyst. 

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.

Dashboards and visualizations are part of how findings get communicated, but they come at the end — the surface of the work, not its core. Most of your time is spent on what sits underneath: methodology, judgment calls on data quality, and shaping how the domain understands its own numbers.

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

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.

Backend Developer (Laravel / PHP)

Remote / Europe

Long-term engagement

Project Overview

We are building a greenfield platform with real business context. An existing and successful system is currently in production — we use it as a reference for business processes and domain knowledge while designing a new system with modern architecture and clear technical direction.

This is not a legacy rewrite or maintenance project. We are building a new system from the ground up, focused on architecture, scalability, and long-term evolution.

We follow a pragmatic engineering approach: we avoid unnecessary abstraction and focus on solutions that deliver real business value.

We optimize for long-term maintainability rather than unnecessary complexity.

What You'll Do

- Design and implement self-contained backend modules within a modular monolith

- Work with clearly defined domain boundaries using DDD principles

- Implement REST APIs and service interactions

- Translate business processes into scalable system design

- Apply Hexagonal Architecture patterns in practice

- Structure domain logic, workflows, and database schemas

- Contribute to architectural decisions and improvements

- Write multi-layer tests (unit, feature, integration)

- Ensure clean, maintainable, and scalable code

- Deliver production-ready systems

You will work closely with the Tech Lead and collaborate with a cross-functional team including Product Owner, UX, and Architects. This is not a task-based coding role — we expect engineering thinking, ownership, and collaboration.

Requirements

- 5+ years of professional PHP and Laravel experience

- Experience with or strong interest in Domain-Driven Design

- Experience with or strong interest in Hexagonal or similar clean architecture patterns

- Solid knowledge of OOP, SOLID principles, and design patterns

- Experience designing and building REST APIs

- Solid SQL knowledge and database optimization (MySQL)

- Experience with Docker or similar containerized environments

- Experience writing tests across multiple layers (unit, feature, integration)

- Ability to work independently and deliver results with ownership

AI-Assisted Development (Required)

AI is a standard part of our engineering workflow. We expect every developer to be comfortable using modern AI coding assistants (such as Claude, ChatGPT, GitHub Copilot, Cursor, or similar) as part of their daily development workflow.

AI is not a replacement for engineering judgment. Developers remain fully responsible for the architecture, correctness, security, maintainability, and testing of the code they deliver.

Candidates who are unwilling to embrace AI-assisted development or do not see it as an essential part of their daily workflow are unlikely to be a good fit for this role.

Nice to Have

- Experience with system decomposition and migration strategies

- Experience with CRM / ERP systems or complex business domains

- Experience with AWS or similar cloud platforms

- Familiarity with event-driven architecture

What We Expect

- Strong focus on code quality and maintainability

- Ability to understand and model real business processes

- Structured and pragmatic approach to system design

- Ability to work within a defined architecture while improving it

- Balance between speed and quality — we ship but we ship well

- Reliable execution in a team environment

- Clear communication and ownership

What We Offer

- Work on a greenfield platform with real business context and clear purpose

- Well-architected codebase built on clean code principles (SOLID, meaningful naming, testability) — static analysis, automated style checks, comprehensive tests are non-negotiable

- Collaboration with a Tech Lead and cross-functional team

- Remote work

- Pragmatic culture focused on delivery and outcomes

Tech Stack

The platform is built with:

- PHP 8.4, Laravel 13

- Modular Monolith architecture with Hexagonal Architecture principles

- Domain-Driven Design (DDD) — Aggregate Roots, Value Objects, Repository interfaces

- CQRS pattern for separating read and write operations

- MySQL 8 as primary data store

- PHPUnit — unit, feature, and integration tests

- Spatie Laravel Data for typed DTOs

- PHPStan / Larastan for static analysis

- OpenAPI / Swagger documentation

- Docker

- Redis

- AWS infrastructure

- CI/CD pipeline for automated checks and deployments

Languages
 

- English: Required (B2 - Upper Intermediate minimum)

- Ukrainian: Strongly preferred — the development team is being built primarily with Ukrainian speakers, so it's the main language for daily team communication. However, strong candidates without Ukrainian will still be considered.
