Legal Counsel at THEON INTERNATIONAL (Filothei-Psychiko)

THEON INTERNATIONAL, a global leader in night vision and thermal imaging systems for military and security applications, has opened a compelling vacancy for an experienced Legal Counsel in Filothei-Psychiko, Greece. This is not just another in-house legal role; it is a front-row seat to the high-stakes world of defence technology, cross-border M&A, and capital markets. For senior lawyers with seven or more years of post-qualification experience, this opportunity offers the rare combination of strategic transactional work and direct exposure to executive leadership in one of Europe's most dynamic defence groups.

Why THEON INTERNATIONAL Is a Legal Career Powerhouse

THEON Group started its operations in 1997 in Greece and has since grown into a globally recognised supplier of cutting-edge night vision and thermal imaging systems. With more than 260,000 systems in service across 73 countries—26 of them NATO members—the group has established a reputation for technological excellence and operational reliability. The parent company, THEON INTERNATIONAL PLC, is listed on the Euronext stock exchange, a milestone that has accelerated its growth and opened new avenues for corporate development.

This is not a back-office legal position. It is a strategic role where legal advice directly shapes the execution of transformational corporate initiatives.

For legal professionals, joining a defence and space industry leader means working on matters that are not only commercially significant but also geopolitically relevant. The legal team at THEON is expected to navigate complex regulatory landscapes, multi-jurisdictional transactions, and sophisticated financing structures—all while maintaining the highest standards of compliance and governance. The company's global footprint, with subsidiaries and production facilities in Greece, Cyprus, Germany, the Baltics, the United States, the Gulf States, Switzerland, Denmark, Belgium, Singapore, and South Korea, ensures that no two days are alike.

Inside the Role: Capital Markets, M&A, and Everything In Between

The Legal Counsel role at THEON INTERNATIONAL is designed for a lawyer who thrives on complexity and variety. The core focus areas are capital markets, banking & finance, and corporate transactions including M&A. As a Legal Counsel, you will be expected to lead and support M&A and strategic transactions—from initial due diligence to post-closing integration. You will advise on capital markets matters, which is particularly exciting given the company's Euronext listing, and provide guidance on corporate governance issues that arise in a publicly listed group.

Beyond transactional work, the role involves negotiating financing and commercial agreements. This requires a commercial mindset and the ability to balance legal risk with business objectives. You will partner closely with senior management and business teams, offering pragmatic advice that helps the company move quickly without exposing it to unnecessary legal exposure. Coordinating external counsel across multiple jurisdictions is another key responsibility, meaning you must be adept at managing outside advisers and ensuring consistent, high-quality legal support across the group.

The Ideal Candidate Profile: What THEON Really Wants

THEON is not looking for a generalist. The ideal candidate will have spent at least seven years in practice, ideally with a mix of top-tier law firm experience and in-house exposure. This combination ensures that you understand both the rigour of private practice and the practical realities of a fast-paced corporate environment.

• Strong background in capital markets: familiarity with equity and debt capital markets transactions, listings, and ongoing obligations.
• Banking & finance expertise: experience negotiating and documenting credit facilities, security arrangements, and other financing transactions.
• M&A and corporate transactions: proven track record managing mergers, acquisitions, joint ventures, and other corporate restructurings.
• Cross-border transaction management: ability to coordinate legal work across multiple jurisdictions and navigate differing legal and regulatory frameworks.
• Commercial mindset: a pragmatic approach that focuses on business enablement while managing risk effectively.
• Stakeholder management: confidence to interact with senior executives, boards, and external partners.
• Superb drafting and negotiation skills: the ability to draft and negotiate complex agreements with precision and commercial awareness.
• Fluency in English: the company operates globally, and English is the working language.

If you meet these criteria, this role offers an unmatched platform to help shape the legal and strategic future of a listed international defence group.

How to Craft a Winning Application for This Legal Counsel Position

Given the seniority of this role, your application must demonstrate not just legal expertise, but also strategic and commercial impact. The first step is to ensure your CV highlights your transactional experience, especially any deals involving cross-border elements or the defence sector. Use quantifiable achievements—for example, the value of transactions you have advised on, or the complexity of jurisdictions involved. A short, punchy profile at the top of your CV can help hiring managers see at a glance that you are a serious candidate.

Your cover letter (or LinkedIn application message) should explicitly connect your background to the role's key pillars: capital markets, banking & finance, and M&A. Mention why the defence and security industry appeals to you, and what you can bring to a listed company with a global footprint. The employer is likely to value candidates who have experience working with top-tier law firms on complex transactions, but also in-house experience that demonstrates business acumen and commercial judgement.

Do not simply list your past responsibilities—show how you have helped previous employers execute successful transactions, solve complex legal problems, and collaborate with cross-functional teams.

Research the company thoroughly before applying. Understanding THEON's product lines, global footprint, and recent announcements will allow you to tailor your application to the company's current priorities. Since the posting does not specify a deadline, early application is strongly advised. The role has already attracted interest from other applicants, so making a strong first impression is critical.

Career Trajectory and Long-Term Impact

Taking this Legal Counsel position is more than a job change—it is a strategic career move. You will be stepping into a high-visibility role that works directly with senior leadership, offering a clear path to more senior in-house positions, such as Senior Legal Counsel, Head of Legal, or General Counsel. The international nature of the group also opens doors to roles in other jurisdictions, as companies value leaders with true cross-border experience.

Working in the defence and space industry adds an extra layer of professional meaning. Your work will directly support technologies that protect armed forces and security services in dozens of countries. For many lawyers, this mission-driven aspect is deeply fulfilling and differentiates the experience from purely commercial sectors.

The company's Euronext listing means you will participate in the ongoing evolution of a public company—dealing with regulatory changes, shareholder expectations, and corporate governance developments. This exposure is invaluable for anyone who aspires to an executive leadership role in a global organisation. Combined with a competitive compensation package and a genuinely collaborative working environment, this role represents an exceptional opportunity for the right lawyer.
