About Lemon.io

Lemon.io is a profitable, growing talent marketplace that connects vetted senior engineers with companies that need them. We've been in business for 10 years, have 60 people across Ukraine, Europe, Canada, and the US, and process over $16M in annual GMV.

We're transitioning from a services-driven marketplace to a technology-driven platform. The product roadmap is wide open. We know what the bottlenecks are, but we are yet to figure out how to solve them. You won't be maintaining an engine, you'll be helping build one.

The Role

We're looking for a PM who operates at the intersection of data, product instincts, and engineering velocity. You'll own product areas end-to-end, from discovery through delivery, collaborating closely with a distributed, async-first engineering team. You will work across our core products for the client's side. 

This is not a coordination role. We want someone who digs into the problem, challenges assumptions, and ships things that move business metrics.

Now let's elaborate :)

What You'll Do

• Directly contribute to business growth by improving the way we work with customers, building billing, customer experience, and operations tooling that helps us move faster
• Own product areas from conception to delivery: define success before writing a single spec
• Drive discovery: user interviews, data analysis, competitive research, hypothesis validation
• Work with AI agents to automate and improve product workflows: hands-on, not just directional
• Prioritize ruthlessly. Decide what to build, what to skip, and what to kill
• Provide enough context for engineers to make smart decisions: no hand-holding, no over-speccing
• Run grooming, planning, and design reviews; lead demos and release notes
• Collaborate with Product Designer and Engineering to ship fast and iterate constantly
• Track and own the business metrics that your product area affects.
  
   

Who You Are
 

• Product-minded and business-first - you connect every feature to a measurable outcome
• Obsessed with simplicity. Complexity is a cost, not a feature
• Proactive: you don't wait for perfect specs to start building things
• Comfortable in async, distributed environments - clear written communication is your superpower
• You can hold a technical conversation with engineers without faking it
   

Experience
 

Must have

• 3+ years of product management experience
• Proven track record of product decisions that directly impacted business metrics (revenue, retention, conversion, activation)
• Experience working in and with distributed, remote engineering teams
• Solid English - you'll work across international stakeholders regularly

Nice to have

• B2B SaaS or marketplace product experience
   

Why Lemon.io

• Profitable and bootstrapped. No fundraising pressure, real business fundamentals
• A pivotal moment: we're building the product, not maintaining it
• Small team, high ownership. Your work is visible and your decisions ship
• eNPS of 63. People here care and stay
• Direct access to founders and leadership - no layers.
   

What We Offer

• Competitive salary in USD
• Full remote with flexible working hours
• 28 working days of vacation per year
• 7 days of sick leave
• Annual reimbursements: health, self-development, travel, home office, mental wellness
• Startup culture with open communication

We are an established designer eyewear eCommerce company with 8+ years in the industry, working with 100+ luxury and designer eyewear brands.
Our business operates across multiple sales channels, supported by a fully customized internal CRM system, warehouse workflows, inventory processes, fulfillment operations, marketplace management, and remote international teams.
If you haven't done this before — or you can't show real results from a previous role — please don't apply. We won't be fit, and neither of us should spend the time. We're hiring proven professionals only.
 

About the Role

The COO will work directly with the CEO and take ownership of daily operations across inventory, fulfillment, logistics, marketplaces, customer support, procurement, product/content operations, and internal systems.
This role requires a person who understands how to manage people, processes, and numbers — especially in a multi-brand retail or eCommerce environment.
We are looking for someone with proven experience in a similar operational leadership role. Relevant experience, real cases, and measurable results are important for us.
 

Key Responsibilities

• Manage and improve company-wide operations across departments.
• Build clear processes, SOPs, reporting, and accountability systems.
• Manage remote teams across Ukraine, New York, and other locations.
• Lead department managers and ensure teams achieve their KPIs.
• Improve inventory accuracy, warehouse productivity, fulfillment speed, and operational efficiency.
• Control fulfillment, logistics, support, and operational costs.
• Identify bottlenecks in the CRM, workflows, reporting, and team execution.
• Work with the CEO to turn business goals into clear execution plans.

THE KPIS YOU'LL OWN
This is the core of the job. We'll talk numbers in the interview, and we'll test how you think about them.
Inventory
–   Inventory turnover & weeks of supply
–   Sell-through rate by brand and by channel
–   GMROI — gross margin return on inventory investment
–   Aged / dead stock as a % of total inventory
–   Stockout / out-of-stock rate and inventory accuracy
Fulfillment
–   Order fulfillment cycle time
–   On-time dispatch & delivery rate
–   Fulfillment cost per order
–   Perfect order rate (accurate, on time, undamaged)
–   Return rate & return-handling time
Cost & margin
–   Contribution margin by channel and by brand
–   Operating expense ratio and cost per order across the P&L
–   Cash conversion cycle
Team & execution
–   SLA adherence across departments
–   Output / productivity per team member
–   On-time delivery of strategic projects

You should read this list and immediately know which levers move each number — and by roughly how much. That instinct is what we're hiring for.
 

WHAT YOU ALREADY HAVE
–   Senior operations / COO experience in eCommerce, ideally multi-brand retail or marketplace.
–   A track record managing 10–15+ people remotely across time zones.
–   Fluency in analytics — you live in dashboards and decide from data, not gut feel.
–   Real, demonstrable KPI results from previous roles. Bring the portfolio.
–   Hands-on experience with CRM / ERP / WMS or workflow automation systems.
–   English at B2+ or higher.
 

HOW WE HIRE
No fluff. We'll ask about specific numbers you've owned, how you moved them, and what you'd do with ours. Expect a practical case study — real scenarios, real data. We work with people who know the numbers cold and know how to lead a distributed team to hit them.
 

WHAT YOU GET
–   Direct partnership with the CEO and real ownership of company-wide operations.
–   Fully remote, flexible schedule (full-time, 40 hrs/week, Mon–Fri).
–   Competitive salary, paid vacation and sick leave, birthday bonus, and team perks.
–   The freedom to build scalable systems instead of babysitting broken ones.
 

Application Note
We are looking for an experienced operational leader who knows how to manage teams through KPIs, not assumptions.
Please apply only if you have relevant experience and can share examples of previous roles, team size, KPIs you managed, and measurable operational improvements you delivered.
