For our partner, we are looking for a Head of Sales Operations & Quality (Web3 / FinTech) 

Who They Are: 

The company is a fully confidential cryptocurrency wallet designed for businesses. They help companies operate with crypto securely, efficiently, and privately. Their team is building a product that combines cutting-edge technology, high security standards, and a seamless user experience.

They don’t need a simple "sales administrator." They need a system architect who will build an environment where the sales team thrives and closing high-value deals becomes an inevitable result of the process.

The candidate won’t be closing deals personally — they will be building the engine that makes sales seamless, scalable, and data-driven. They are scaling their next-gen crypto-processing infrastructure, and the mission is to ensure the sales force operates with surgical precision.
 

Your scope of responsibility:

• Design and implement a world-class onboarding system. The goal is to drastically reduce the "Time-to-ramp" for new team members.
• Monitor calls, chats, and negotiations to directly influence and improve the quality of client interactions.
• Master HubSpot. Optimize the funnel, automate routine tasks, and maintain data hygiene to ensure total pipeline transparency.
• Lead workshops on value-based selling and the specifics of the Web3 market. You don’t just point out mistakes; you provide the tools to fix them.
• Monitor CAC, LTV, and conversion rates at every stage. You provide the CBDO with a "health report" of the department through clear, actionable dashboards.
   

Who they’re looking for:

• 5+ years in Sales Ops, Enablement, or Quality Management within FinTech, Banking, or Crypto.
• You understand the crypto-landscape (custody, liquidity, compliance) and don’t need a dictionary to explain what a fiat on-ramp is.
• A track record of mentoring teams. You know how to turn a newcomer into a top-performer through structured coaching.
• You live by metrics. You don’t "feel" the team is doing well — you know it because the data says so.
• You hate chaos. When you see a bottleneck, your first instinct is to build a system to automate or eliminate the problem.
   

Why Join Them:

• Join a global FinTech product that’s truly reshaping the market landscape.
• Work with smart minds on complex challenges — they’re not “playing startup,” they’re building the infrastructure of the future.
• Be part of a team free from toxicity — only open dialogue, mutual respect, and real professionalism.
• Receive fair compensation — clear structure, results-driven rewards, and flexible reviews.
• Grow with them — clear goals, transparent career paths, no unnecessary bureaucracy.
• Enjoy support — English classes, continuous learning, gym benefits, and family bonuses.
• Key specialists get relocation support to Cyprus.
• Fast-tracked application process — because time matters.
   

Smart people. Big challenges. A business that builds the industry.

Our Mission and Vision
At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.

Why are we introducing Product Ops

Think of 🏎️ Product Ops as the pit-crew for our product org — the crew that keeps the car running at optimal speed while the drivers (PMs, designers, engineers) focus on steering, innovation, and delivering value.
Digital product work is unpredictable — delays, messy data, broken handoffs, tool chaos — those can easily turn “sprints” into sludge. Product Ops is what stands between that chaos and the ability to deliver clean, high-velocity, high-quality work.
Instead of building the product itself, Product Ops builds and runs the operating system — frameworks, tools, workflows — so that the rest of the org can move fast, aligned, and without friction.
Product Ops isn’t “just operations” — instead, it’s a force multiplier.

Importantly, this role is not about processes for the sake of processes.
This role is all about reality checks. You’ll systematically align our product with what customers and commercial teams actually experience.

What You Will Own

— Customer feedback loop: Structured system connecting Sales, Merchant Ops, and Integration insights directly into product discovery and planning

— Product context from the field: Translating sales demos and merchant interactions into actionable product intelligence (what works, customer expectations, objections)

— Scalable processes: Clear frameworks for product involvement in custom solutions, demos, and merchant initiatives — replacing ad-hoc coordination with repeatable systems

— Feature rollout: Controlled deployment of new features to existing customers, including timing, communication, feedback collection, and iteration

— Team management & development: Design & Tech Writing teams

Why This Role Is a Career Accelerator

— High-impact role — you directly shape how the entire product organization works
— N-1 level to the CPO — real strategic influence, not a support role
— Immediate measurable impact — your work instantly affects delivery speed, transparency, and quality
— You build from zero — no legacy chaos, no rigid structures
— Wide operational playground — planning, discovery, delivery, rituals, documentation, metrics

Team Setup

You will directly lead: Tech Writing & Product Design Team
Your lead & mentor: Artem Sadurskyy, CPO
 

Our Ideal Candidate

— Proven experience in Product Operations, Product Management, Product UX, or Product Design Operations, driving complex initiatives from idea to impact.
— Experience working closely with product designers, UX, and product managers — not only with engineering teams
— Strong product mindset and customer obsession — ability to connect product decisions with real customer and commercial context
— A track record of building, improving, or scaling product processes that actually work — and keep working as teams grow
— Hands-on people leadership experience, supporting teams, setting clear expectations, and raising the bar
— Strong command of planning, discovery, and delivery, with confidence in:

— prioritisation and roadmap governance
— capacity planning and SLAs
— product and delivery metrics (velocity, predictability, quality)

— Fluency with modern product tools: Jira, Confluence or Notion, Figma, and analytics platforms
— A data-driven mindset, comfort with ambiguity, and the ability to turn complexity into clarity

Soft skills that truly matter here: systems thinking, clear structured communication, ability to influence without authority, leadership & ambition, results-oriented mindset, conflict management, and strong cultural fit.

The Points That Make You Stand Out
Experience in fintech/payments, B2B, and marketing acquisition.
 

Why Join Solidgate?
High-impact role. You’re not inheriting a perfect system — you’re building one
Great product. Solidgate is the financial infrastructure for modern Internet businesses: from subscriptions to fraud, chargebacks, and indirect tax
Part of Endeavor. A global community of the world’s most impactful entrepreneurs
Massive growth opportunity. This role will be a career-defining move
Top-tier tech team. Proven engineers, modern engineering culture, CI/CD, metrics, automation

About

Hi, I’m Bohdan:)

I’m setting up a new multi-asset trading desk and I’m looking for a Trading Operations Analyst to help with analytical and operational tasks around trading data. This role is research/support-focused: you will work with datasets, reports, and post-trade analytics to help decisions be made faster and with higher confidence.

What you’ll do

• Perform post-trade analysis and prepare concise reports (tables + charts)
• Break down performance by 
  • instruments/tickers
  • time windows
  • trade reasons/tags (if provided)
  • holding time / entry quality buckets (if applicable)
• Detect anomalies and data-quality issues (missing fields, outliers, inconsistent logs)
• Produce clear visualisations and summaries that can be used in decision-making
• Communicate findings clearly and defend conclusions when challenged

Requirements

• Strong statistical analysis skills (practical, not academic)
• Strong Python for data analysis (pandas / numpy; polars is a plus)
• Strong data visualisation skills (matplotlib / plotly; ability to present insights)
• Ability to state conclusions under pressure (clear, direct, defendable)
• High attention to detail and strong ownership of output quality
• Ukrainian PE (FOP) or equivalent legal ability to provide services (B2B)
• Must have full legal right to provide services — no visa sponsorship

Note: Strong analytical thinking and clarity of reasoning are valued more than years of formal work experience.

Nice to have

• Prior experience with trading / market data
• Familiarity with performance metrics (PnL attribution, drawdown, slippage concepts)
• Availability for regular Warsaw/London meetups

Compensation

I’m open to negotiating pay depending on task difficulty:

• hourly rate, or
• fixed price per deliverable

Selection process

1. Intro call (fit + expectations + availability) + Light analytical task (quick, practical)
2. Post-trade analysis test (more realistic, based on sample data)

Disclaimer

• Contract / freelance only
• No visa sponsorship
• Long-term collaboration possible if the fit is strong
