Chief Information Security Officer Greater Belfast, United Kingdom Area

About Ctrl Alt

Ctrl Alt is designing and operating the on-chain infrastructure powering digital capital markets globally. We bring together a unique blend of expertise in financial markets and cutting-edge in-house technology to deliver tailored, compliant solutions in the alternative assets space. Since launching in 2022, we’ve tokenized over $1.5 Billion in assets across real estate, private credit, funds, litigation finance and more.

We’re building a high-performance, people-first culture where ambitious individuals can thrive. We move fast, think big and hold ourselves to a high bar, while keeping things collaborative, open and genuinely fun. At Ctrl Alt ideas win on merit, teams work closely with leadership, and everyone has a voice in shaping what we build next.

We believe that hard work should come with real reward. You won’t just join a company - you’ll help build one. Last year alone, we grew from 17 to 50 people, and this year we’re going faster and further. That means real responsibility, meaningful impact, and the opportunity to grow alongside a company that’s redefining the future of finance through the tokenization of alternative assets.

If you’re excited by scale-up energy, ownership, and the chance to help shape both a business and a culture, Ctrl Alt is where you can do the most rewarding work of your career.

The Opportunity

We’re looking for a Chief Information Security Officer, reporting to our CTO, to own security across Ctrl Alt. Our platform holds and moves tokenized real-world assets for institutional clients, so security is central to the product. Clients, partners and regulators judge us on it before anything else.

We’ve grown quickly, and our security work has grown with us. You’ll take a capable small team and the controls we already have, and turn them into a security programme that can scale with the business across several regulators. You’ll set the strategy, decide on risk, and be the person the board, clients and regulators look to on security.

You’ll work closely with Engineering, Product, Compliance and Operations, and with the leadership team. The role is based in our Belfast office.

What you’ll be doing:

Own Ctrl Alt’s security strategy and roadmap, and make sure it supports where the business is going

Lead and grow the security team, setting a high bar for hiring, delivery and development

Own information security risk across the company, deciding where we accept, reduce or transfer it, and explaining those decisions clearly

Set the controls for our on-chain infrastructure, including key management, custody, wallet security and smart contract assurance

Build a security programme that stands up to regulatory scrutiny across our jurisdictions, including operational resilience requirements such as DORA

Lead incident response, from preparation and testing through to handling a live incident and the review afterwards

Represent Ctrl Alt on security with the board, institutional clients, auditors and regulators

Lead certification and assurance work such as ISO 27001 and SOC 2, and use it to raise standards rather than just pass audits

Build security into how Engineering designs, builds and ships, so the secure option is also the easy one

Manage third-party and supply chain risk as our partners and integrations grow

This role will be a great fit if you:

Have led an information security function in a regulated environment, such as financial services, fintech or digital assets

Have built or scaled a security team and programme in a fast-growing business

Make clear risk decisions under uncertainty, and can explain the trade-offs to technical and non-technical audiences

Are credible in front of boards, regulators and institutional clients, and comfortable being challenged there

Have run real incidents and owned the outcome, including saying early and plainly when something has gone wrong

Care about details, because in security small gaps become big problems

Hold a high standard for yourself and your team, and help others across the business raise theirs

Communicate clearly in writing, from board papers to incident updates

Nice to haves:

Hands-on experience securing blockchain infrastructure, digital asset custody or smart contracts

Experience with regulators in more than one jurisdiction, such as the FCA, Central Bank of Ireland or VARA

A recognised security certification such as CISSP or CISM

Experience of interacting directly with board level stakeholders, plus regulatory bodies
