Testronic has recently undertaken a series of high‑level appointments across its worldwide offices, reinforcing its commitment to delivering top‑tier quality assurance and partnership services. Among the most notable additions is Mike Guttman, who has been named Vice President of Senior Partnerships. Guttman arrives with a strong background in client relationship management, having previously held the role of client partner at Keywords Studios, as well as serving as a senior business development manager in the interactive entertainment sector.
In his new capacity, he will be responsible for cultivating and expanding Testronic’s relationships with major clients, guiding strategic collaborations, and ensuring that the company’s service offerings align closely with the evolving needs of its partners. Supporting Guttman’s efforts is Nicole Closson, appointed as Business Development Manager. Closson’s mandate is to broaden commercial coverage and provide additional support to partners both regionally and globally. She brings a wealth of experience from her former positions at Keywords Studios, where she worked as an enterprise account executive, and at Unity, where she acted as senior account executive for the Parsec and SyncSketch products.
Her expertise in managing large‑scale accounts and her familiarity with the gaming and immersive media landscapes position her well to drive growth and deepen client engagement. In the European hub of Warsaw, Testronic has promoted Mateusz Kałuża to the role of QA Director. Kałuża’s appointment follows a series of senior testing roles at Lionbridge Games, where he honed his skills in quality assurance leadership.
Speaking about the strategic importance of the Warsaw office, Kałuża noted, "Warsaw brings together deep QA expertise, experience and a real understanding of what developers need from a testing partner. Our continued investment in the team ensures we grow that expertise locally, fully connect it with Testronic's wider global capabilities and deliver consistently for partners wherever they are based." This statement underscores the company’s intent to integrate local talent with its global network, creating a seamless service experience for developers worldwide. Further strengthening the global partnership team, Lily Guerreiro has joined as Global Partnerships Senior Manager. Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she was instrumental in forging cross‑border collaborations and expanding the firm’s market reach.
Her role at Testronic will focus on aligning the company’s partnership strategy with broader industry trends, ensuring that Testronic remains a preferred testing partner for leading studios and publishers. The Manila Centre of Excellence has also seen senior talent added to its ranks.
Daniel Bowie Soriano steps in as Senior QA Manager, bringing a robust background in overseeing complex testing pipelines and quality frameworks. Alongside him, Ivan Balanay has been appointed QA Trainer, a role that supports Testronic’s investment in the Testronic Academy and the development of the next generation of QA professionals. The company highlighted that Balanay’s appointment "further supports [its] investment in developing the Testronic Academy and building the next generation of QA expertise," emphasizing a long‑term commitment to skill development and knowledge transfer. Chief Revenue Officer Michael Fitzgerald commented on the broader strategic picture: "Our Centres of Excellence bring together talented people, specialist expertise and leadership, and connect those capabilities across a genuinely global organisation.
The investments we are making in New Orleans, Warsaw and Manila, alongside our presence in London, further strengthen the expertise available to our partners. By continuing to invest in outstanding people, we can deliver an exceptional Player‑Focused, Partner‑First and Outcomes‑Led service to our clients." Fitzgerald’s remarks reflect Testronic’s philosophy of combining localized expertise with a cohesive global delivery model, ensuring that each client receives tailored, high‑quality testing solutions. These leadership changes come on the heels of a recent reshuffle at the top of the company.
Earlier this month, Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. In addition, Michael Fitzgerald was announced as the new Chief Revenue Officer, while Samantha Williams took on the position of Chief Commercial Officer. Fitzgerald previously served as a client partner at Keywords Studios, and Williams held the titles of Global CRO and Head of Europe at Testronic, bringing deep institutional knowledge to their new responsibilities. Overall, Testronic’s series of senior appointments signals a deliberate strategy to enhance its global footprint, deepen technical expertise, and reinforce its partnership model.
By integrating seasoned professionals from industry leaders such as Keywords Studios and Unity, and by investing in regional centers of excellence, the company aims to provide a seamless, high‑quality testing experience that meets the demanding standards of modern game development. The expanded leadership team is poised to drive growth, foster innovation, and maintain Testronic’s reputation as a trusted partner in the interactive entertainment ecosystem.
