Hiring Process

1. Interview with Recruiter
2. Interview with Team Lead
3. Final Interview — CTO & CEO

Inception-1 creates AI-driven products that help people feel more connected and less alone. Our mission is to build meaningful digital experiences that blend technology with empathy — and to prove that AI can be both human and transformative.

We are looking for a Product Owner to take end-to-end ownership of one of our web-based AI companionship products and drive its next stage of growth.

This is a highly hands-on role for someone who wants to own a product as a business — not just manage a backlog or ship features. You will be responsible for understanding what prevents the product from growing, identifying the highest-impact opportunities, and turning them into measurable improvements.

Your core focus will be on LTV, conversion, retention, monetization, and overall product quality. You will work closely with engineering, marketing, content, creative, and payment teams while remaining personally involved in analytics, experimentation, prioritization, and product decisions.

Responsibilities

• Own the product end-to-end and drive its development in alignment with business goals.
• Increase LTV, conversion to payer, retention, and overall monetization performance.
• Identify product bottlenecks, usability issues, and growth opportunities, and turn them into clear priorities.
• Run product experiments and evaluate their impact on key metrics.
• Conduct deep product analytics using tools such as Amplitude and BI dashboards.
• Work closely with engineering to improve product quality, resolve critical issues, and deliver high-impact changes.
• Collaborate with marketing, content, creative, and payment teams to improve the full user journey.
• Analyze competitors and market benchmarks to identify opportunities for product improvement.
• Improve monetization and payment flows together with relevant stakeholders.
• Continuously evaluate whether shipped changes create measurable value for users and the business.
   

Requirements

• Proven experience owning a B2C subscription product or a substantial product area end-to-end.
• A strong track record of improving product metrics such as LTV, conversion, retention, or revenue.
• Strong analytical skills and hands-on experience with product analytics tools such as Amplitude and BI dashboards.
• Ability to independently build and interpret funnels, cohorts, dashboards, and product performance reports.
• Strong product thinking: the ability to quickly identify what is not working, understand why, and propose practical solutions.
• A highly hands-on approach — comfortable going deep into the product rather than managing from a distance.
• Strong ownership mentality and the ability to operate autonomously, move fast, and take full responsibility for outcomes.
   

Nice to Have

• Experience with AI-driven consumer products.
• Experience with AI companionship, social discovery, dating, entertainment, or other engagement-heavy B2C products.
• Experience with payment-sensitive or high-volume subscription products.
• Experience in gaming, affiliate-driven products, or other highly performance-oriented B2C environments.
• Vibe-coded pet projects / features.
   

What we offer

• Flexible work format: you can work remotely or from our comfortable office in Kyiv’s Podil district — whatever works best for you
• Our office has secure shelters and uninterrupted internet, water and electricity. If you choose to work from the office, we’ll take care of the routine: breakfasts, lunches, snacks and fruits, lounges, massages, and other office-life benefits are waiting for you

Requirements

• 6+ years of QA experience with a strong track record of delivering high-quality software
• Strong manual, exploratory, and risk-based testing skills
• Experience developing and implementing QA strategy at a team or product level

About the Company

Our client is a financial technology services provider dedicated to expanding global access to digital assets by building innovative solutions in the cryptocurrency ecosystem. Their products provide exchanges, liquidity solutions, prediction markets, and enterprise-grade white-label integrations for institutional clients worldwide.

We are looking for an exceptional, cutting-edge AI-Native Product Manager to own our core Institutional Trading & Derivatives product suite. This is an elite technical product role where deep financial domain mastery meets absolute state-of-the-art AI orchestration.

Key Pillars of Success

To excel in this role, you must bring a battle-tested foundation across three non-negotiable pillars:

1. Cutting-Edge AI-Native Execution: You don't just use ChatGPT or Claude for PRDs and prototyping. You operate with autonomous agents, MCP (Model Context Protocol) integrations, browser/computer use, and human-in-the-loop review loops to dramatically multiply your operational throughput.
2. Deep Trading & Derivatives Mastery: You possess a deep, structural understanding of institutional market mechanics, order lifecycles, margin systems, liquidation engines, funding rates, oracles, exposure, and hedging.
3. End-to-End Ownership & Measurable Impact: Your ownership doesn't end at handing docs to devs or launching on staging. You own the full lifecycle—from discovery, build, and QA to client rollout, adoption, and iteration—backed by self-derived, quantified metrics (e.g., SQL-verified impact).

What You'll Do

• Product Ownership: Take complete end-to-end ownership of our white-label institutional trading, derivatives, and risk management infrastructure.
• Agentic Workflow Integration: Leverage autonomous AI agents and MCP servers to automate complex product research, spec generation, QA verification, and client delivery workflows.
• Institutional Client Rollout: Partner directly with institutional clients and B2B partners to deeply understand their trading workflows, capture complex requirements, and drive product adoption.
• End-to-End Execution: Drive features through the complete lifecycle: discovery, system spec definition, hands-on engineering alignment, QA validation, launch, and post-launch analytics.
• Data & Impact Analytics: Autonomously query databases (SQL) and analytics tools to track, measure, and optimize real client usage and performance metrics post-launch.
• Engineering & Business Alignment: Challenge technical and business assumptions constructively, maintaining direct, transparent communication across cross-functional engineering teams.

AI-Native Expectations

We are looking for candidates who operate at or above the absolute cutting edge of AI tooling:

• Agentic Workflows: Hands-on experience building or utilizing MCP (Model Context Protocol) integrations, autonomous loops, or computer/browser-use agents.
• Execution & Leverage: Using AI as a force multiplier across all product phases—from automated code/spec reviews and workflow automation to deep data processing and client communication.
• Technical Integrity: Using AI to elevate your productivity without substituting AI output for genuine domain expertise or critical engineering judgment.

Who You Are

• Autonomous & Proactive: Capable of taking a broad product domain and generating tangible, visible value within your first 90 days without step-by-step guidance.
• Transparent & Honest: Grounded in high integrity, objective self-awareness, and clear communication. You know your strengths, acknowledge knowledge gaps directly, and never bluff technical answers.
• Systems Thinker: Comfortable reasoning about APIs, data flows, state machines, edge cases, and complex risk models alongside senior engineers.

Qualifications

• English: Upper-Intermediate to Advanced (both written and verbal) for high-stakes institutional communication.
• Experience: 4+ years of software product management experience, specifically within fintech, crypto trading platforms, or institutional finance.
• Domain Expertise: Proven hands-on experience with institutional trading infrastructure, derivatives (perpetuals, futures, options), risk mechanics, margin, and liquidity.
• B2B / Client-Facing Delivery: Demonstrated track record of launching white-label or enterprise B2B products directly for external institutional clients.
• AI-Native Mastery: Practical, advanced usage of modern agentic AI tools and environments (MCP, Cursor, Claude Code, autonomous loops).
• Data Competency: Solid experience writing SQL queries independently to measure feature performance, user funnels, and adoption metrics.

Bonus Points:

• Software development or engineering background.
• Direct experience running or supporting a trading desk, market-making operations, or liquidity adapters.
• Deep knowledge of crypto-native derivatives protocols, Web3 infrastructure, or prediction markets.

We Offer

• Flexibility & Hubs: Flexible working hours with physical office access in Ukraine and Poland (Wroclaw).
• Health & Wellness: Medical Insurance in Ukraine and Multisport program in Poland.
• Time Off: Paid vacation, sick leaves, and observance of official holidays.
• Growth & Support: Corporate English classes up to three times a week, plus mentoring and educational budgets.
• Contractor Support: Complete tax and accounting services provided for Ukrainian contractors.
• Equipment: High-end hardware and development equipment provided by the company.
• Culture: Regular corporate activities (team buildings, tech talks, parties) combined with an advanced bonus system.

What the role is about

We are looking for a confident and organized Client Operations Admin to join the back-office team supporting one of our UK-based clients — a law firm working within the real estate sector.

This is a varied role combining client communication, administrative work, process support, document management, and general back-office responsibilities.

Phone communication is an important part of the daily workflow. The expected call volume is approximately 15 incoming and 15 outgoing calls per day, although this may vary depending on workload.

• Over time, identify process gaps and help design and implement improvements.
• Perform miscellaneous tasks on an ad hoc basis to support team operations.

• Take ownership of assigned tasks and ensure they are followed through to completion.

   

Required Experience:

• At least 2 years of professional work experience.
• Previous experience in administration, operations, back-office support, customer support, or a similar role would be an advantage.
• Experience working independently and managing multiple responsibilities.
• Previous experience within a legal, real estate, or professional services environment would be helpful, but is not required.

English

• Strong spoken English and confidence communicating over the phone.
• Strong written English skills.
• Comfortable communicating with UK-based clients and professionals.
• Ability to communicate clearly and professionally in different situations.

Technical Skills

• Confident user of Microsoft Office.
• Experience working with back-office systems, CRM platforms, databases, or other business software.
• Comfortable working with digital documentation and structured workflows.
• Confident working with numbers and checking information for accuracy.
• Ability to quickly learn new software, tools, and internal processes.

Soft Skills

• Strong organizational skills and attention to detail.
• Confidence and professionalism in client communication.
• Ability to work independently with limited supervision.
• Strong sense of ownership and responsibility.
• Ability to prioritize multiple tasks and stay organized in a fast-paced environment.
• Comfortable following structured processes and procedures.
• Proactive approach to identifying and resolving issues.
• High level of accuracy when working with documents, numbers, and client information.
• Flexibility and willingness to handle different types of tasks depending on business needs.
• Willingness to learn new processes and contribute to their improvement.

Location

• Ukraine is preferred, but we are also open to candidates based in European countries where we can arrange the delivery and return of company equipment via Nova Post.

Working Schedule: Monday – Friday

Working Hours: 11:00 AM – 7:30 PM Ukraine time, including a 1-hour lunch break.
