• Acting as a key member of the engineering team responsible for deploying autonomy solutions across diverse UAV platforms.
• Developing robust interfaces between autonomy algorithms and drone flight controllers.
• Integrating and testing full-stack autonomy solutions on partner platforms, often in close collaboration with partner engineering teams.
• Providing structured feedback to the autonomy development team, based on observations from field tests and operational flights.
• Traveling to partner sites to work on-site and ensure the solutions function reliably in demanding real-world conditions ("in the dirt"). You will mostly be working with our Ukrainian partners.

What we expect from you

• Strong Proficiency in working in a fully terminal-based Linux environment without reliance on GUIs, shell scripting for automation and deployment tasks, Linux file system and command-line tools, and debugging system-level issues using the Linux terminal.
• Experience working with drone flight controllers such as Ardupilot, or PX4.
• Familiar with embedded Linux devices such as Raspberry Pi’s, NVIDIA Jetsons.
• Solid understanding of UAV components and hardware, including battery management and practical electronics, with hands-on experience. Ideally you have built, flown, and debugged a drone yourself
• Practical experience building and deploying Docker containers.
• Experience of both Python and C++ is a plus.
• A willingness to pick up and learn new concepts quickly and to self-acquire missing background knowledge.
• A high degree of autonomy, determination and grit in making cool tech work.
• Being comfortable travelling often in Ukraine and for extended durations (up to 3 weeks)
• Full time availability (40 hours) and work regularly on-site in Ternopil.
• A valid driver's license.

​​​​​​​
While having the perfect background is nice, if you are able to present evidence of outstanding engineering and execution capability we are interested in talking regardless. If you are the right fit, we believe in your ability to pick up the required background knowledge on the fly.

What we offer

• Competitive salary (level to be discussed individually based on interview results).
• 25 vacation days per year.
• Reimbursed travel expenses and company laptop.
• Working in an international, world-class team of engineers and entrepreneurs solving real-life problems with amazing technology.
• Large freedom in how you work and implement solutions, project ownership is incredibly important to us.
• The opportunity to take technical risks, to implement stuff the ‘right’ way and to iterate quickly with tight feedback loops. We are innovating, learning is to be expected.
• Responsibility over the things you implement, you are the expert on what you build.

About Us

We build intelligent platforms that help teams make better decisions in complex environments.

Our core product is an adaptive workspace that analyzes workflows, communication, and performance in real time, turning everyday activity into clear strategic insights.

Instead of dashboards and reports, we provide living systems that learn from how people work and continuously optimize processes behind the scenes.

Our technology is used by fast-growing companies that need clarity, speed, and precision in their operations.

You’ll be part of a small, highly skilled team working directly with leadership to shape a product used at scale.

What You’ll Be Building

As part of our core engineering team, you will design and scale the internal intelligence layer of the platform.

Your work will directly shape how our system learns, connects to external services, and supports users in real time.

You will:

• Architect autonomous AI agents that operate inside our workspace
• Create data flows between our platform and external services
• Develop systems that adapt to user behavior and improve over time
• Turn experimental ideas into stable product features

Your Day-to-Day Work

You will work across product, engineering, and leadership to bring new capabilities to life.

Typical responsibilities include:

• Designing interaction models between users, AI agents, and datasets
• Building integrations with CRMs, analytics tools, and cloud services
• Developing automation pipelines and backend services in Python and Node.js
• Prototyping new features and testing them with real users
• Monitoring system performance and iterating rapidly

Technical Environment

Our stack is focused on flexibility and fast experimentation.

You’ll work with:

• Python as the primary backend language
• Node.js / TypeScript for integrations and services
• Modern LLM APIs (OpenAI, Anthropic, and others)
• Retrieval-augmented generation and vector databases
• Workflow and orchestration platforms
• REST APIs, webhooks, and distributed services

What We’re Looking For

We care more about problem-solving ability than rigid backgrounds.

Ideal candidates typically have:

• 3+ years of experience building production systems
• Strong engineering fundamentals
• Hands-on experience with AI or ML-powered products
• Confidence working with modern language models
• Experience connecting multiple SaaS platforms
• Ability to write clear, maintainable code

How You Work

You’ll thrive here if you:

• Enjoy working with incomplete or evolving requirements
• Take responsibility for systems end-to-end
• Balance experimentation with reliability
• Communicate clearly in English
• Stay curious and continuously improve your craft

Growth Path

This role is designed for engineers who want to move beyond feature implementation.

Over time, you’ll:

• Shape core platform architecture
• Define internal development standards
• Mentor other engineers
• Lead major product initiatives
• Grow into technical leadership roles
