Head of Operations

Callstack supports and inspires top industry leaders in shipping better digital products and services to their users. We are a team of high-level experts in cross-platform development and consultancy. We co-create the technology, collaborate with the Meta team on setting the direction for the future growth of the React Native framework, and much more!

We are recognized in the React Native Community as contributors to Open Source projects, organizers of React Universe Conf, and speakers at international conferences. We also organize regular community meetups in our HQ in Wrocław, Poland.

We truly believe that you can get the best out of people when you give them a chance to participate and develop. At Callstack, you are the one to decide in which area you want to grow; you’ll have an individual self-development budget to empower your competencies and gain new skills.

Our goal is to give every employee the opportunity to speak up and introduce their ideas to build the future together.

As we continue to grow, we are looking for leaders who want to build leverage across the company - not just manage a function. For the right person, this is a chance to join a successful business with strong foundations, real momentum, and the ambition to scale how it operates without losing speed, quality, or edge. This is one of those roles.

• At least 6+ years of experience in operations-focused, senior managerial roles, ideally in fast-paced, innovation-driven IT, tech, or consulting environments
• Strong track record of execution in real business environments
• Experience building or running parts of a business, not only advising it
• Combine strategic thinking with hands-on execution and ownership
• Comfortable working side by side with a CEO and taking responsibility for outcomes
• Ability to lead through influence across functions, not only through hierarchy
• Excellent project and stakeholder management skills
• Highly data fluent and use data to drive decisions, not just report on them
• Clear and structural communication with strong executive-level communication skills
• Experience driving organizational change, transformation, or continuous improvement
• Think in terms of how AI can augment workflows, decision-making, and execution and actively apply it in day-to-day work
• Strong ownership, proactivity, and a bias for action

Your primary focus:

• Co-create and operationalize company strategy together with the CEO, in close collaboration with the CTO (Founder)
• Drive end-to-end execution of strategic initiatives across the organization, together with other members of the leadership team
• Lead and continuously improve planning processes across strategy, OKRs, budgeting, and reporting
• Build and scale performance management systems, including KPIs, OKRs, reporting, and operating cadences
• Establish and strengthen execution discipline across teams
• Embed AI into operational processes and decision-making to increase speed, quality, and leverage

Your broader scope:

• Own and evolve internal project management standards and capabilities (PMO)
• Coordinate cross-functional initiatives and ensure alignment at the leadership level
• Build a more data-driven management culture and stronger decision-making processes
• Lead operational transformation initiatives, including the adoption of AI across workflows
• Strengthen continuous improvement culture through process excellence, leaner ways of working, automation, and workflow optimization
• Over time, help shape and develop a small team of project, operations, and process specialists

What success looks like early on:

• Rapidly map and assess how the company currently operates across teams, processes, and reporting
• Identify the most critical gaps, inefficiencies, and misalignments
• Start solving the highest-impact problems immediately — not just documenting them
• Bring structure and clarity to ongoing initiatives and priorities
• Establish visibility and control over key projects and execution streams
• Introduce initial standards for planning, reporting, and execution discipline
• Identify and implement opportunities where AI can meaningfully improve how the organization operates - from decision-making to execution speed and process efficiency

Direct partnership with the CEO, with close exposure to the Board and leadership team. High visibility and exposure to key stakeholders. Real ownership and impact on company trajectory. Opportunity to shape how the organization operates at scale. A role that can grow materially as the company evolves.
