We’re hiring a Product Lead (Analytics) for a leading Marketing Automation Cloud and Customer Data Platform (CDP) serving major brands across the CIS region. The platform helps large and mid-sized companies unify and activate customer data to drive revenue through personalized, data-driven marketing.
This is not another dashboard tool. It’s an expert system designed to move CMOs from business goals → insights → actions → measurable growth.
About the Product

What’s happening with revenue
How marketing impacts it
Which levers to pull to drive growth
Core areas:
Business metric decomposition
OKR-style goal tracking
Revenue attribution
AI-powered assistant with automated analysis & recommendations
Funnels
Loyalty analytics
Comparable market references include:

Role & Team
The Product Lead (Analytics):
Owns all products within the Analytics team (not a single feature).
Leads a team of ~8–10 people (engineering + design).
Has 2 direct reports (one analytics-focused, one product).
This role sits at the intersection of analytics consulting, product strategy, and execution.
Responsibilities
1. Customer outcomes = product success
Build measurable success stories: “saw → acted → got results.”
Drive product adoption and improve key metrics.
Build backlog based on customer + CSM feedback, not assumptions.
2. Quality gate for analytics (non-negotiable)
Acts as the quality gate before release.
Validates data correctness, methodology, and UX.
Stops releases when numbers aren’t trustworthy, methodology is weak, or UX is poor.
3. Analytics consulting → productization loop
Runs customer deep-dives (discovery / JTBD).
Personally explores customer data to diagnose problems and recommend actions.
Transforms one-off consulting insights into scalable product capabilities:
repeatable workflows, templates, automated recommendations, and UI patterns.
4. Vision → execution
Adopts the existing product vision and makes it their own.
Breaks strategy into actionable increments.
Communicates priorities clearly and aligns them with company-level goals.
5. Team leadership
Provides clear product direction to engineering and design.
Mentors product talent.
Contributes to hiring and performance management.
What We Expect From You
Proven experience launching a successful B2B analytics product with paying customers.
Strong hands-on data skills:
Comfortable working directly in SQL
Confident in Excel / Google Sheets
Deep understanding of attribution, experimentation, and validation
Able to personally dig into data to validate hypotheses and identify issues.
Uses GPT / AI assistants to accelerate analysis — not as a substitute for understanding.
Consulting mindset: able to sit with a client, break down metrics, identify root causes, and propose an action plan.
Comfortable making product decisions under uncertainty via prototyping and rapid feedback.
Strong argumentation skills — able to overcome resistance across people and processes.
High standards for analytics UX and methodology.
Russian at professional or native level.
Nice to Have
Experience in CRM marketing / MarTech.
Experience building AI-driven data products.
What We Offer
Ambitious vision: an expert system from goals to actions — not another BI tool.
AI embedded into the product core.
Direct impact on customer revenue and business results.
Transparent culture (open finances and salaries).
High autonomy and strong feedback loops with customers.
Remote-first — no mandatory office attendance.
Preferred: ability to travel for onboarding (~2 weeks; travel co-funded).
Flexible schedule.
Unlimited vacation (aligned with the team).
Sick leave without paperwork.
Accredited IT company.
Equipment provided: MacBook, monitors, noise-canceling headphones, and all necessary peripherals.
Well-being program toward education, healthcare, psychotherapy, sports, or travel.
Self-development support: Co-funding for courses, workshops, coaching, negotiation training, business writing, emotional intelligence, and more.
Employment formats: Payroll / contractor / self-employed — multiple formats possible.
Hiring Process
Zoom screening interview with a Hire5 recruiter
Short written test task (text-based)
Soft-skills interview (3 competencies; STAR/case format)
