📍 This role is office-based in Kyiv during the probation period. After successful onboarding, there is flexibility to transition to a hybrid or remote work format.

Our Technological R&D Center is where innovation takes shape. It’s the heartbeat of our technical evolution, where we don’t just follow trends — we define how they work within the Apple ecosystem. 

As a Senior Research Engineer, you will work in a cross-functional squad with engineers and researchers, where you can blend deep engineering research with high-impact commercial delivery, without the friction of bureaucracy. Your research won't just sit on a shelf; it will power the next generation of MacPaw products.

In this role, you will:

• Research and implement technical solutions for on-device AI model execution on macOS
• Build functional prototypes and adapt them to the evolving requirements. You will bridge the gap between R&D hypotheses and stable, high-performance technology
• Develop internal tools and frameworks for the TR&D team to accelerate the testing of new AI approaches and facilitate the early adoption of innovative technologies across MacPaw
• Partner with AI researchers, designers, and product teams to clarify technical details, define edge cases, and propose architectural solutions in high-uncertainty environments
• Conduct deep-dive sessions for the engineering team on research findings, document successful implementation cases, and act as a technical expert in joint projects with academic institutions

Skills you’ll need to bring:

• Strong knowledge of the Apple ecosystem, with a deep focus on macOS internals (app sandboxing, XPC services, system daemons, etc.)
• Profound background with Swift/Objective-C and experience with architectural design for complex, high-performance systems
• Ability to find solutions for undocumented technical challenges (e.g. reverse engineering techniques or exploring low-level system behaviors)
• Experience in hypothesis validation, performance benchmarking (RAM/CPU/Battery), and documenting research findings into clear technical reports
• Practical experience in building functional application prototypes from scratch and bridging the gap between an idea and a stable POC
• Upper-intermediate English & fluent Ukrainian
   

As a plus:

• Basic understanding of ML concepts (embeddings, tokens, LLM architecture)
• Practical experience with Python
• Experience working with MLX or CoreML
• Background in product-focused companies

What We Offer:

• We are a Ukrainian company, and we stand with Ukraine against the russian aggression
  We maintain workplaces for the mobilized Macpawians and provide financial support to colleagues or their families affected by the war. Here, you can also read about the MacPaw Foundation, which intends to help save the lives of Ukrainian defenders and provide relief to as many civilians as possible.
• We are committed to our veterans
  Our Veteran Career and Empowerment Program is designed to ensure our veterans and active military personnel receive the recognition, support, and opportunities they deserve.

• Your health always comes first
  We guarantee medical insurance starting on your first working month. For those abroad, you can receive a yearly Medical insurance allowance as compensation for managing your medical expenses.

Also, we have two cats living in the office, and you are welcome to bring your pets to the office (we have separate floors for cats and dogs).
• Time-off policy that covers life’s needs
  Convenient personal time-off policy to help you take care of essential matters in your personal life, and parental leaves. On top of all that, sabbaticals are open after 5 years of being with MacPaw.
