This position is open only to Ukrainian residents currently living in Ukraine, preferably in Kyiv or Lviv.

We are searching for an experienced Project Manager.

Our team handles mission-critical, multi-app, multi-platform distributed systems, addressing serious threats in the real world around us. This role requires full ownership of outcomes in mission-critical projects that operate in complex and dynamic environments. If you are comfortable taking responsibility in sensitive, socially impactful projects and thrive in environments that demand clarity, judgment, and accountability, this role may be a strong fit for you.

The company puts strong emphasis on maintaining a comfortable and supportive team environment. We expect you to be attentive to team dynamics, appreciate individual strengths, and navigate nuances thoughtfully to foster effective collaboration. The ability to balance delivery goals with a healthy team atmosphere will be very valuable for this role.

What makes you a great match #

• The skill of seeing the bigger picture — understanding the team as a system and helping your team members see the interdependencies.
• Immaculate communication skills are a must — because mind-reading isn’t part of the job.
• Ability to see and maximise value in people, processes, and tools.
• A natural inclination to keep everything around you organised, design processes and follow them.
• Creativity — new ideas and experiences are vital to achieving great results.

What you’ll do #

• Own the delivery process and ensure it supports project goals and meets constraints. This includes designing the workflow, implementing, and continuously improving it.
• Collaborate with technical experts to create realistic development/delivery plans that lead towards project outcomes.
• Support R&D initiatives by breaking down the uncertainty and facilitating the process.
• Coordinate teams and organise processes for effective cross-team capacity allocation and collaboration.
• Drive results through internal company and team initiatives.
• Establish a monitoring system for delivery progress to ensure meeting the contract terms and to report to the management team.
• Manage the knowledge base for projects and products.

Requirements #

• Proven 5+ years of experience as a Project Manager, including 3+ years in large, complex projects.
• Expertise in planning, designing, and executing large initiatives.
• Expertise in managing cross-functional teams, co-managing them based on project needs, in collaboration with the project’s technical lead.
• Experience working with product teams and in a startup environment.
• Attention to detail and focus on quality.
• Extreme ownership and diligence.
• Deep understanding of classic project management methodologies (PMBOK).
• Strong skills to communicate effectively and manage conflicts.
• Upper-intermediate English, written and spoken.
• Availability for business trips to Kyiv and Lviv as required by work.

Nice to have #

• Technical background (education and/or work experience in software development, engineering, quality assurance, etc).
• Understanding of information security, IoT and hardware, systems engineering, infrastructure, etc.
• Understanding of how large distributed systems are built or how they work (e.g. the scale of power plant control systems)
• Understanding of design and manufacturing processes in automation systems.
• Desire to work on extremely innovative projects and minimise chances for chaos ahead of time.
• Experience working in a multicultural context.

Hiring Process #

1. Resume review — up to 7 business days.
2. Test task — estimated time hours 2-3.
3. Introductory meeting with the Head of department.
4. Technical interview with the Head of department and PM.
5. Background check.
6. Offer discussion.

What to expect from us #

• We build applications for clients, write code for developers, and document how it all works — for both.
• Everyone on the team is happy to help, but we also respect each other’s time and know how to find answers ourselves.
• Tech writing isn’t our favourite task, but we do create solid technical documentation when needed, and we’re lucky to have a tech writer to help with that.
• We prefer doing things right the first time over patching things endlessly later.
• We value healthy perfectionism, a sense of beauty in engineering, and a good sense of humour.

What we offer #

• Opportunities to work across technologies and projects: cryptography, software engineering, information security, ML security controls, cryptographic protocols, hardware protection, reverse-resilient mobile apps, and web apps for millions of users.
• Quarterly performance reviews, regular one-on-one meetings with your manager, and ongoing support to help you succeed and grow professionally.
• Quarterly compensation reviews, aligning pay with performance and market benchmarks.
• Performance and reward bonuses.
• 21 business days of vacation, plus sick, mental health, and emergency days to use when genuinely needed.
• Combination of in-office and remote work as needed, flexible scheduling, and a winter slowdown period.
• Conferences, books, courses, internal knowledge sharing, workshops, writing blog posts and research papers, giving talks, and contributing to open-source parts of our products — choose what aligns with your professional goals.
