Ctd - Cluster Technology Director

Building better and safer isn't a slogan, but the way we show up in the world.
THE ROLE
We're looking for a forward-thinking
Cluster Technology Director
to define, lead and continuously transform the technical vision for our
Energy & Critical Infrastructure (ECI)
cluster.
This is where we help utilities, grid operators, and technology providers keep energy flowing safely and reliably.
Our teams build and assure the software behind smart metering and smart grids, substation and grid management, renewable energy, and the critical infrastructure that modern life depends on.
As CTD, you own the technical direction of the cluster.
You set the architecture principles and reference roadmaps, you are the technical authority for safety-critical and mission-critical energy systems, and you make sure our engineering choices stay credible with customers, sound on cybersecurity and regulation, and reusable across projects.
You work closely with multiple teams, raising the technical bar for everyone around you and turning energy-sector complexity into clear, buildable engineering.
Note: this is a single role with global impact across the cluster, open to applications from different cities in Portugal.
WHAT YOU'LL DO
Define and lead the technology vision, principles, and reference roadmaps for the cluster, aligned with company strategy and the company's global direction
Act as the technical authority for regulated, safety-critical energy software, across metering, head end systems, substations, grid, and renewables
Grow the cluster on solid foundations, with architectures and assets that scale and get reused across customers
Set the bar on cybersecurity, interoperability, and secure design for critical infrastructure, working to multiple standards
Be the escalation point for the hardest architectural, safety, and regulatory calls, and make them fast
Bring AI into energy delivery where it solves real problems, balancing innovation with security and regulation
Work with the CTO to build the capabilities that sharpen Critical's edge as a trusted energy engineering partner
Mentor senior engineers and architects across the cluster, and represent Critical in industry and standards forums
HOW YOU CAN INSPIRE
You make hard calls quickly and with autonomy, taking decisions at your level rather than pushing every one upward, and you own what follows.
You focus effort where it actually matters and step away from the opportunities that are not right for Critical, rather than chasing every deal.
You see AI as the biggest shift of this generation and you act on it.
You reshape how delivery itself works with AI, you do not just adopt the tools, and you raise the bar for everyone around you.
You communicate with clarity and honesty, without ambiguity.
You bring urgency and positive energy in equal measure.
WHAT WE'RE LOOKING FOR
5+ years of software engineering and technical leadership experience, with significant time in energy, utilities, or critical infrastructure and in safety-critical or mission-critical systems
Strong grasp of the energy ecosystem, from utilities, TSOs and DSOs to OEMs, metering vendors, and technology partners
Expertise across the relevant architectures: smart metering and grid, head end systems, substation automation, embedded and connected platforms, energy data platforms
Solid command of cybersecurity, interoperability, and secure design for regulated environments
A practical view on AI and ML in operational energy, including value, risk, validation, and security
Ability to communicate complex technical and regulatory topics clearly to customers, teams, and senior leadership
Leading through influence, mentoring senior technical people across projects and customers
Strong sense of responsibility toward safety, reliability, quality, and ethics
Strategic, pragmatic, and resilient, with a bias for clarity, credibility, and execution
Deeply aligned with Critical Software's mission and values
Excellent English communication skills
