We are looking for a Sales Development Representative to take full ownership of the client journey: from the initial “cold” outreach to the signed contract.

We need a partner who understands the lead generation process, the art of communication, knows how to build trust, and is ready to turn prospects into long-term clients. You will have full autonomy, clear goals, and the resources needed to succeed.

📋 Your Mission

You will own your pipeline. Your focus will be on quality interactions rather than spamming. You will have total ownership of the entire cycle.

Unlike in fragmented sales teams, there are no risky handovers here — you never have to worry about a colleague losing context or dropping the ball on a relationship you worked hard to build

We value systemic thinking and high energy. We’d love to talk if:

• You are proficient in sourcing — you know how to build ICP and use tools for automation outreach.
• You understand the psychology of sales: not just “pushing,” but solving the client’s problem.
• You are a listener, not just a talker. You ask the right questions to uncover needs.
• You are disciplined with CRM tools and understand that “if it’s not in the CRM, it didn’t happen.”
• You are self-driven and comfortable working autonomously without micromanagement.
• English: Upper-intermediate/Advanced

If you don’t have some of these skills, it’s okay, we’re ready to teach you how to become better!

We treat sales as the engine of our business, and we treat our salespeople as partners:

1. Financial Growth: Competitive base salary + commissions. Your income directly reflects your results.
2. Real Impact: No bureaucracy. Your feedback from the market directly influences our product/service development.
3. Culture of Trust: We focus on results, not hours tracked. We provide the tools, you provide the talent.
4. Support: Quality onboarding, access to necessary software/databases, and a team that has your back.

We believe sales is about human connection. If you share this vision, let’s talk!

• Collaborate with product, data engineering, and AI teams to ensure high availability, quality, and reliability of the fetched data.
• Contribute to existing re-usable components to enhance development velocity.
• Follow best practices in software development when implementing new and refactoring the existing codebase.

• Conversations feel natural, not robotic
• Recruiters trust the summaries and scores
• The AI asks smart follow-ups instead of rigid scripts
• Drop-offs decrease over time
   

How this role works:

• You’ll work closely with:
  • Integration / Backend Engineers
  • Recruiters & hiring managers
  • Product leadership
     
• Small team, fast iteration, real production use cases.

• Startup culture with open communication. Our current eNPS score is 82.
• Competitive salary in USD
• Full remote work with flexible working hours

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
