Equals5 helps pharmaceutical companies run precisely targeted ad campaigns on social platforms by identifying healthcare professionals and the consumer signals that reach them. The Identity team builds the data, scoring, and targeting systems that make this possible.

We are looking for a Data Scientist/Analyst  to join the Identity team at Equals5. 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 

• 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.

• Fully remote with flexible hours, with working overlap in CET ±2 hours for syncs.
• AI-Native Environment: We provide licenses for Claude Code and encourage using the bleeding edge of AI tech — both for daily work and as part of product logic.
• High-Impact Role: You will directly shape how we identify, score, and reach healthcare professionals — the core business of our domain.

• No Bureaucracy: Fast decisions, no legacy processes, focus on results.

We are looking for a QA Team Lead who will be responsible for quality assurance across multiple engineering teams and play a key role in building a scalable testing strategy. You will act as the quality owner for the larger development team, ensuring the reliability of the entire product data flow from external API integrations to end-user dashboards.

In this role, you will lead the QA team and work closely with engineering team leads, implementing automation, quality gates, and testing best practices within development workflows. You will have the opportunity to shape the company-wide quality strategy, scale automation efforts, and influence product quality across the entire engineering organization.

Responsibilities
- Lead a QA team of 3–4 engineers, including task assignment, code reviews, mentorship, and supporting professional growth.
- Own end-to-end quality across all engineering teams.

- Build and maintain a cross-team testing strategy covering the full data flow — from API ingestion through data pipelines to the end-user dashboard.
- Design and implement automated test suites, including E2E (Playwright/Cypress), API, integration, and regression tests.
- Establish quality gates in CI/CD pipelines, ensuring no code is released without passing automated checks.
- Coordinate release testing across teams, ensuring that changes in one system do not impact downstream consumers.
- Define and track quality metrics, such as test coverage, defect rates, time-to-detection, and regression frequency.
- Collaborate closely with team leads (Platform, Integrations, etc.) to embed quality practices into development workflows.
- Manage test environments and test data, ensuring realistic and reproducible testing scenarios across all domains.

Requirements
- 5+ years of experience in QA/SDET, including 2+ years in a leadership role managing a QA team.
- Strong experience with test automation, using Playwright, Cypress, or similar E2E frameworks.
- Experience testing APIs (REST), both manual and automated, including contract and integration testing.
- Understanding of data pipeline testing, including validation of data flow from source APIs through transformation layers to analytics systems.
- Ability to work across multiple tech stacks (PHP/Laravel, Vue.js, Python, SQL). You are not required to be a developer, but you should be able to read and understand code.
- Experience with CI/CD integration, embedding automated tests into build pipelines and managing test environments.
- Strong communication and stakeholder management skills — you will coordinate with 3–4 team leads and communicate quality status clearly.

Nice to Have
- Experience with BigQuery and/or ClickHouse data validation.
- Knowledge of advertising/marketing tech domain (Meta API, LinkedIn API). 
- Experience with performance/load testing (k6, Locust, Artillery).
- Familiarity with GCP services (Cloud Run, Cloud SQL, Cloud Scheduler).
- Understanding of healthcare/pharma compliance requirements.
- Experience with visual regression testing.

What We Offer
- Fully remote with flexible hours (aligned with EU timezones for syncs).
- Influence on the quality assurance strategy across the entire engineering department.
- A cross-team role with visibility into every part of the product.
- AI-first tooling.
- Claude Code licenses and cutting-edge AI development workflows. 
- A team with no bureaucracy, decisions are made fast.
