Jobs Ukraine

We’re looking for a Chief Executive Officer (CEO) to take full ownership of one of AIBY’s core product groups — up to $70M ARR consumer subscription business — and scale it into its next phase of profitable growth.

Your mission – maximize the Net Profit and Long-Term Value (LTV) of your multi-platform portfolio of apps across iOS, Android, and web by aligning product innovation with data-driven performance marketing.

Unlike a solo founder, you aren’t starting from zero. As a Business Unit CEO, you have:

• immediate access to AIBY’s historical data from 70+ apps to see what works
• centralized Legal, Finance, and HR so you can focus 100% on the product and the users
• significant UA budgets and infrastructure already in place

What you will do:

• P&L Ownership: you’re 100% accountable for the revenue, marketing spend, and operational costs of your unit
• Strategic Roadmap: define the “Why” and the “When”. You decide which features to build based on their projected impact on retention and monetization
• Growth & Monetization: work hand-in-hand with your UA Lead to optimize ROAS (Return on Ad Spend) and Payback Periods. You’ll oversee the subscription funnel, A/B testing, and paywall optimizations
• Cross-Functional Leadership: build, structure, and scale a high-performing team across Product, Growth, Marketing, Engineering, and Design
• Resource/ Capital Allocation Strategy: you have the autonomy to decide where to “bet” your resources. If a specific app in your unit is scaling, you pivot the team’s focus there immediately
• Partnership with the Board and Founders: you’re involved in strategic decision-making at the C-level, with direct impact on business metrics, financial results, and the product ecosystem

What you should have:

• 7+ years of experience in product-based B2C businesses (subscription, mobile/web)
• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)
• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit
• Competitive fixed compensation + performance-based bonus + long-term incentive structure
• The opportunity to scale a category-leading product portfolio into a global market-defining player
• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy

About the Role

Haiqu builds the software layer between quantum algorithms and quantum hardware. We are looking for a Middle+/Senior Software Engineer with strong Python experience and a generalist mindset to help build the core systems behind our runtime and orchestration.

The role combines Python engineering, compiler infrastructure, systems programming, and scientific computing.

Previous quantum computing experience is not required.

What You’ll Work On

• Design a Python framework for quantum computing.
• Developing compiler-style IRs, transformations, and JIT/AOT/native compilation.
• Exploring ways to lower higher-level programs toward efficient native execution.
• Integrating new hardware and execution providers.
• Build runtime system for quantum program executions
• Owning features end-to-end — from core library changes to backend APIs, database changes, and production integration.
• Turning research prototypes into reliable production software.

• Refactoring and improving the architecture of a large Python codebase.

   

What We’re Looking For

• Strong Python plus systems-level programming experience, ideally C++ or Rust.
• Strong software architecture and engineering fundamentals.
• Comfortable making backend/API and database changes when needed.
• Deep understanding of compilers, runtimes, programming languages, or execution engines.

• Experience with LLVM, MLIR, JIT/AOT compilation, IR design, ASTs, type systems, or code generation.

   

We are looking for a strong software engineer who can work deeply on compiler and systems problems while also being comfortable going across the stack when that is what it takes to deliver a feature.

Nice to Have

• Scientific or numerical computing.
• CUDA or GPU programming.
• Machine learning.
• Distributed systems.
• Quantum computing or Qiskit.

• Interest in learning quantum computing.

   

Who Would Be a Good Fit

This role is particularly suitable for a strong Python engineer who also enjoys compiler, runtime, or lower-level systems work.

You do not need to be a quantum computing expert. We care more about strong engineering fundamentals, compiler or systems experience, and the ability to work with complex technical problems.

We are primarily looking for candidates based in Ukraine, with a preference for Lviv.

Why we exist:

Swarmer develops software that makes drones autonomous and allows them to operate together, in large, coordinated teams—no pilots needed. Our technology has been battle-tested in Ukraine—the world’s most intense proving ground for drone warfare.

In March 2026, we became the first Ukrainian defense startup to go public on NASDAQ, following a $15M Series A—the largest investment in a Ukrainian defense tech company since the start of the war.

Working at Swarmer means operating at the intersection of engineering rigor and frontline reality. The problems and environments are complex, and the stakes are very real. We built this software to enable democratic nations to defend themselves.

If you are motivated by building resilient systems that matter and by seeing the direct impact of your work, you’ll find purpose here.

Who we’re looking for:

We are looking for a Head of Integration—a technically grounded leader who will own and scale our integration function as we move from early-stage deployments into full operational tempo.

This role sits at the intersection of two critical domains:

• Vendor integration—bringing third-party systems (video navigation, comms modules, and others) into our stack.
• Customer integration—making our software run on our customers’ platforms: aerial, ground, and maritime.

This position is for someone who can take chaos, structure it, and turn it into repeatable results—fast.

What you’ll do:

1. Vendor & Customer Integration

• Manage end-to-end integration of third-party solutions into the Swarmer stack.
• Own the integration of Swarmer’s software onto customer platforms—aerial, ground, and maritime.
• Lead R&D initiatives on new platform integrations and serve as the primary technical point of contact with hardware vendors.

2. Team Leadership & Process Development

• Build and scale the integration org: define team structure, hire and develop leads, grow a team across multiple sub-teams.
• Design and implement structured, predictable integration workflows to ensure consistent delivery timelines for every new customer onboarding.
• Establish and maintain documentation standards across the function, including Jira, process documentation, and integration playbooks.

What we need:

• Strong technical background: solid working knowledge of embedded systems, Linux, and hardware platforms.
• Experience managing engineering teams; comfortable leading multiple sub-teams and developing leads.
• Hands-on experience at the intersection of software and hardware.
• Systematic approach to work: ability to scope, estimate, and deliver.
• Documentation discipline—Jira, process docs, integration playbooks.
• Great organizational and communication skills: capable of aligning several stakeholders to drive project outcomes; effective cross-domain communication.
• Stress resilience, fast problem-solving, persistence, and an ownership-driven mindset.
• Excellent English level.

What would be an advantage:

• Senior embedded or Linux engineer background with a path into engineering management.
• Experience in defense, aerospace, automotive, robotics, or other hardware-intensive industries.
• Experience working with large hardware vendors.
• Familiarity with UAV platforms and their technical stack.
• Military or volunteer UAV experience.
• Technical degree (electronics, robotics, aviation, or similar).

What you’ll get:

• A dynamic environment with a unique opportunity to directly influence and see the impact of your work.
• A mission-driven role in a company building technology that directly supports Ukrainian and global defense capabilities.
• The opportunity to work on one of the most advanced and practically tested autonomy products in the defense-tech market.
• Exposure to multiple domains: hardware, autonomy, operations.
• Competitive salary, insurance, and legal benefits (reservation, etc).
• A high-ownership culture where initiative, clarity, and execution matter more than bureaucracy.
