Proekspert is an IT company providing tailored, high-impact solutions for the manufacturing and smart device industry across Europe. We build and operate mission-critical systems that power connected devices, industrial automation, and large-scale digital platforms. 

Are you a Technical Product Owner who wants to work closely with engineers, understand how systems behave, and guide a product that thousands of users rely on daily? Do you enjoy shaping requirements, prioritizing what truly matters, and standing behind decisions that influence a long-running, business-critical platform? Then this challenge is for you. 

What is the project about? 

Since 2018, Proekspert has collaborated with a leading global HVAC manufacturer to design, build, and run the Cloud platform behind their connected devices. 

The solution keeps tens of thousands of devices connected in real time. Technicians and end-users rely on round-the-clock control, monitoring, and performance insight. The platform has been a business-critical component for years, backed by a demanding, high-throughput backend that handles thousands of requests per second. 

The team owns continuous development, new functionality, maintenance, and 3rd-level support. You will step into a mature product with both legacy corners and modern patterns and a team that owns its decisions, from technologies to ceremonies.  

What will you do? 

• Prioritise incoming work from the client and sequence it against their business targets so the team always knows what comes next. 

• Filter and refine requirements: review inbound communication, answer client emails, gather missing details, and ensure developers receive clear, actionable work. 

• Keep the backlog healthy- achievable, well-shaped, and worth building toward. 

• Hold the roadmap view and advise developers on abstraction choices that must survive future features. 

• Coordinate scope and timelines with other teams and stakeholders who depend on what this platform ships. 

• Handle client communication, questions, meetings, discussions, etc. 

• Read code and join technical discussions to understand how the system behaves, not just how it’s described. 

• Keep the team organised and heard, and contribute also to hiring and mentoring.  

• Use AI tooling to draft, analyse, test, or summarise while reviewing the result and owning every decision. 

We are looking for a team member who: 

• Has a minimum of 8 years of experience working in the technology field, and at least 5 years of hands-on software development before moving into a PO or team lead role.  

• Can read code at a working level- enough to understand behaviour and answer questions without relying on a developer. 

• Understands how web apps, native mobile clients, and cloud-to-cloud integrations differ in behaviour and constraints. 

• Has prioritized work against business goals and gathered requirements directly from stakeholders, shaping them into actionable work. 

• Can make independent decisions and support shared team decisions. 

• Chooses and utilizes the right tools, including AI, to get the best result. 

• Has excellent cooperation and communication skills and can consultatively approach the client. Can present, explain, and defend a point of view. 

• Is fluent in English and Estonian. 

Nice to Haves:

• HVAC, energy, or industrial domain background. 

• IoT or device-connectivity experience. 

• Familiarity with .NET, Azure, MS SQL, or equivalent stacks. 

• Experience with platforms or APIs that other teams build on. 

• Work on consumer or partner mobile/web applications across multiple brands and markets. 

Founded by engineers for engineers, Proekspert is a place built around autonomy, trust, and meaningful work. We value individual freedom, decision-making, and proactiveness. This team owns the majority of its decisions from technologies to processes and works together for the best possible result. 

What we offer 

• Meaningful, steady work with real-world impact in projects that improve everyday life for thousands of users 

• Real autonomy: organise your own work without unnecessary bureaucracy. 

• An experienced team who support and mentor each other. 

• A culture that values the well-being of our people and their families. 

• An exciting benefits package.
