Testronic has announced a wave of senior‑level appointments across its worldwide operations, underscoring the company’s commitment to deepening its expertise and expanding its service footprint. The most prominent addition is Mike Guttman, who steps into the role of Vice President of Senior Partnerships. Guttman brings a wealth of experience from his previous tenure as a client partner at Keywords Studios, where he was responsible for nurturing high‑value relationships and driving strategic growth.
Prior to that, he held a senior business development manager position, giving him a solid foundation in both client acquisition and partnership management. In his new capacity at Testronic, Guttman will oversee the cultivation of senior‑level alliances, ensuring that the firm’s testing and quality‑assurance services align closely with the evolving needs of major game developers and interactive media creators. Supporting Guttman’s efforts is Nicole Closson, who joins the team as Business Development Manager.
Closson’s mandate is to broaden commercial coverage and provide dedicated support to partners both regionally and globally. She arrives with a strong background in enterprise account management, having served as an enterprise account executive at Keywords Studios and later as a senior account executive for Parsec and SyncSketch at Unity.
Her experience in managing complex, multi‑stakeholder accounts equips her to navigate the intricate landscape of game development partnerships, where timelines are tight and quality expectations are high. In Europe, Testronic’s Warsaw office has reinforced its leadership with the appointment of Mateusz Kałuża as QA Director.
Kałuża’s career has been built on senior testing roles at Lionbridge Games, where he honed his understanding of the technical and creative demands placed on quality‑assurance teams. Speaking about his new role, Kałuża emphasized Warsaw’s strategic importance: "The city brings together deep QA expertise, extensive experience, and a genuine grasp of what developers expect from a testing partner. Our ongoing investment in the local team allows us to grow that expertise, integrate it fully with Testronic’s global capabilities, and consistently deliver results for partners wherever they operate." His leadership is expected to strengthen the synergy between the Warsaw hub and Testronic’s other Centres of Excellence, fostering a seamless flow of knowledge and best practices.
Further enhancing the company’s global partnership network, Lily Guerreiro has been named Global Partnerships Senior Manager. Guerreiro previously served as Global Business Development Manager at Keywords Studios, where she was instrumental in scaling international client relationships and driving cross‑border collaborations.
In her new role, she will focus on aligning Testronic’s service portfolio with the strategic objectives of its worldwide client base, ensuring that the company remains a trusted partner for studios seeking comprehensive testing solutions. The Manila Centre of Excellence has also seen senior talent added to its ranks.
Daniel Bowie Soriano joins as Senior QA Manager, bringing a robust background in managing large‑scale testing projects and a keen eye for process optimization. Working alongside him is Ivan Balanay, appointed as QA Trainer. Balanay’s role is pivotal to the development of the Testronic Academy, an internal training initiative aimed at cultivating the next generation of QA professionals. The company highlighted that Balanay’s appointment "further supports our investment in developing the Testronic Academy and building the next generation of QA expertise," reinforcing Testronic’s dedication to continuous learning and skill advancement.
Chief Revenue Officer Michael Fitzgerald provided perspective on the broader strategic intent behind these appointments. "Our Centres of Excellence bring together talented people, specialist expertise and leadership, and connect those capabilities across a genuinely global organisation," he said. "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 highlight Testronic’s philosophy of placing both the end‑player experience and partner success at the heart of its operations. These leadership changes follow a recent reshuffle at the highest level 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 conjunction with Kerr’s appointment, Michael Fitzgerald was confirmed as Chief Revenue Officer, and Samantha Williams took on the role of Chief Commercial Officer. Fitzgerald previously served as a client partner at Keywords Studios, while Williams held the position of global CRO and head of Europe at Testronic, bringing deep internal knowledge and market insight to her new responsibilities. Collectively, these appointments signal Testronic’s aggressive strategy to reinforce its global footprint, enhance its service depth, and maintain a competitive edge in the fast‑evolving gaming and interactive media sectors.
By integrating seasoned professionals with proven track records in partnership development, quality assurance, and commercial strategy, Testronic aims to provide a more cohesive, responsive, and high‑quality experience for developers worldwide. The expanded leadership team is poised to drive forward initiatives that focus on player satisfaction, partner collaboration, and measurable outcomes, ensuring that Testronic remains at the forefront of the industry’s quality‑assurance landscape.
