Testronic has recently undertaken a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to expanding its leadership depth and service capabilities. Among the most notable additions is Mike Guttman, who has been named Vice President of Senior Partnerships.
In this role, Guttman will be responsible for cultivating and overseeing strategic relationships with Testronic’s most important clients, ensuring that the firm’s partnership model remains both innovative and results‑driven. Guttman arrives at Testronic with a solid background in the interactive entertainment services sector.
Prior to joining, he spent several years as a client partner at Keywords Studios, where he helped shape large‑scale outsourcing strategies for leading game developers. He also held the position of senior business development manager, a role that required him to identify new market opportunities, negotiate complex contracts, and drive revenue growth.
His blend of client‑facing experience and business development acumen makes him a natural fit for steering Testronic’s senior partnership agenda. Supporting Guttman’s efforts is Nicole Closson, who has been appointed 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 previous tenure at Keywords Studios, where she served as an enterprise account executive, as well as from Unity, where she operated as senior account executive for the Parsec and SyncSketch product lines.
Her proven track record in managing enterprise‑level accounts and her deep understanding of the gaming ecosystem will help Testronic extend its reach into new territories and strengthen existing relationships. In the European hub of Warsaw, Testronic has elevated Mateusz Kałuża to the position of QA Director. Kałuża’s career has been built on a foundation of senior testing roles at Lionbridge Games, where he honed his expertise in quality assurance processes for complex, multi‑platform titles. Speaking about the appointment, Kałuża emphasized the strategic importance of Warsaw as a centre of testing excellence: "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 highlights the company’s vision of integrating localized talent with a cohesive global service network. Further reinforcing the global partnership framework, Lily Guerreiro has joined the leadership team as Global Partnerships Senior Manager. Guerreiro previously held the role of Global Business Development Manager at Keywords Studios, where she was instrumental in forging cross‑border collaborations and expanding the firm’s footprint in emerging markets.
Her addition signals Testronic’s intention to maintain a unified, worldwide partnership strategy that aligns with the evolving needs of game developers and publishers. The Manila Centre of Excellence, a critical node in Testronic’s service delivery model, has also seen senior talent added to its ranks.
Daniel Bowie Soriano steps in as Senior QA Manager, bringing extensive hands‑on testing experience and a reputation for building high‑performing QA teams. Complementing him is Ivan Balanay, who assumes the role of QA Trainer. Balanay’s appointment is described by the company as a further boost to its investment in the Testronic Academy, an internal training program designed to nurture the next generation of quality assurance professionals. By strengthening its training capabilities, Testronic aims to ensure that its staff remain at the cutting edge of testing methodologies, automation tools, and industry best practices.
Chief Revenue Officer Michael Fitzgerald summed up the strategic rationale behind these moves, stating: "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." This comment underscores the company’s belief that geographic diversification of expertise—paired with robust leadership—creates a more resilient and responsive service offering. The leadership reshuffle follows a broader executive transition earlier in the month, when Testronic announced the appointment of Sonia Kerr as Chief Executive Officer.
Kerr succeeds Sharon Baylay‑Bell, who stepped down from day‑to‑day management to assume the role of company chair, providing strategic oversight. In conjunction with Kerr’s appointment, Michael Fitzgerald was confirmed as CRO, and Samantha Williams was named Chief Commercial Officer.
Fitzgerald’s background includes a stint as a client partner at Keywords Studios, while Williams previously served as Testronic’s global CRO and head of European operations, bringing a deep understanding of both the commercial and operational dimensions of the business. Collectively, these appointments reflect Testronic’s strategic emphasis on building a leadership team that combines industry‑specific knowledge with a global perspective. By placing seasoned professionals in key roles across its major hubs—New Orleans, Warsaw, Manila, and London—the company aims to deliver a seamless, high‑quality testing experience for its partners worldwide.
The expanded senior team is expected to drive innovation in QA processes, enhance client engagement, and support the company’s growth trajectory in an increasingly competitive market. In summary, Testronic’s recent senior hires—Mike Guttman, Nicole Closson, Mateusz Kałuża, Lily Guerreiro, Daniel Bowie Soriano, and Ivan Balanay—along with the broader executive changes, signal a decisive move toward strengthening its global partnership network and elevating its service standards. The firm’s continued investment in talent, training, and regional expertise positions it to meet the evolving demands of game developers, ensuring that quality assurance remains a cornerstone of successful game launches and sustained player satisfaction.
