At Critical Software, building better and safer isn’t a slogan - it’s the impact we aim for in every project. We use technology to solve meaningful challenges, helping organisations work smarter, operate more reliably, and create positive change for people and the planet.
Our people sit at the heart of this mission. Their talent, curiosity, and commitment to quality push us forward and shape the way we deliver technology that truly matters.
We are now looking for a Head of Finance & Performance to work alongside the CFO. This is a company-wide mission spanning sales, delivery and support functions - owning how performance is measured, challenged and reported across the business, and giving senior management a clear, independent read on how the budget is being executed and where the numbers are really going.
This is a role for someone who wants to shape how a high-growth tech group runs its finances, and not just report on them. You'll challenge the standard for how the business plans, forecasts and explains its performance, and you'll have the standing to push back when the numbers don't add up. You'll also help us build a modern, AI-augmented finance function: we expect hands-on experience using AI tools and deploying agents to take repetitive work off the team.
Critical Software has grown organically and through investments and joint ventures across the technology space, and finance sits close to that activity: company-wide reporting, transaction support, post-deal integration. The role offers wide exposure across the business and a real seat at the table on the decisions that shape it.
What do we expect from you?
- Own company budget and performance reporting - track where each business area is against plan, surface what's really driving variances, and make sure senior management sees the picture early
- Partner with business-area leaders on their budgets and forecasts by pressure-testing the assumptions and raising the bar on how the business plans
- Identify financial risks early and bring senior management not just an issue, but a recommended path through it
- Act as the financial check on major client and supplier contracts before they're signed, protecting margin and flagging risk in commercial commitments
- Monitor live contract performance and surface risks that area-level reporting can miss
- Review statutory close and financial statements for SNC / IFRS Compliance
- Validate tax compliance in coordination with internal teams and external advisors
- Oversee how procurement decisions land financially across the company (both the spend itself and the policy discipline behind it)
- Be the company's primary face to external auditors, banks and tax authorities
- Drive the AI and automation agenda inside finance — identify where agents can take on more of the workload and show the team the way forward
What makes you a good candidate for this role?
- Degree in Finance, Management, Economics, Accounting or related field
- 10–15+ years in finance, with at least some of that time at a senior level in a multi-entity or fast-moving environment
- Strong knowledge of SNC / IFRS and Portuguese taxation (IRC, VAT, IRS)
- Experience with ERP systems and BI tools (Power BI or similar)
- Experience in a tech, multi-entity or international group is an advantage
- International experience is a plus
- Hands-on experience building or deploying AI/agent-based tools in a finance context - we're looking for someone who's actually done this, not just read about it
- Strong analytical and communication skills, with the ability to present complex financial matters clearly to different audiences
- Independent, intellectually curious, and willing to hold a position under pressure
- Excellent English language skills, spoken and written
