Testronic has undertaken a sweeping series of senior‑level appointments across its worldwide operations, underscoring the company’s commitment to strengthening its leadership bench and expanding its service capabilities. Central to this wave of promotions is the elevation of Mike Guttman to the role of Vice President of Senior Partnerships.
Guttman arrives with a robust background in client‑facing roles, having previously held the position of client partner at Keywords Studios, where he cultivated deep relationships with high‑profile gaming and entertainment clients. Prior to that, he served as a senior business development manager, gaining extensive experience in identifying growth opportunities, negotiating complex contracts, and steering cross‑functional teams toward shared objectives.
In his new capacity at Testronic, Guttman will be responsible for overseeing the company’s most strategic partner relationships, shaping long‑term collaboration frameworks, and ensuring that the firm’s service delivery aligns tightly with the evolving needs of its clientele. Joining Guttman in the business development arena is Nicole Closson, who steps into the role of Business Development Manager.
Closson’s appointment is intended to broaden Testronic’s commercial reach and to provide additional support to partners both regionally and on a global scale. Her professional pedigree includes a stint as an enterprise account executive at Keywords Studios, where she managed large‑scale accounts and drove revenue growth through tailored solutions. She also spent time at Unity, acting as a senior account executive for the Parsec and SyncSketch products, where she honed her ability to translate technical product value into compelling business propositions. Together, Guttman and Closson will work to deepen existing relationships while also scouting new market segments where Testronic’s testing expertise can add measurable value.
In the European hub of Warsaw, Testronic has named Mateusz Kałuża as its new QA Director. Kałuża brings a wealth of experience from his previous senior testing positions at Lionbridge Games, where he oversaw quality assurance processes for a variety of high‑profile titles. Speaking about the appointment, Kałuża highlighted Warsaw’s strategic importance: "The city combines a deep reservoir of QA talent, seasoned experience, and a nuanced understanding of what developers truly need from a testing partner.
Our ongoing investment in the local team allows us to nurture that expertise, integrate it seamlessly with Testronic’s global capabilities, and consistently deliver high‑quality outcomes for our partners, wherever they operate." His leadership is expected to further cement Warsaw’s reputation as a centre of testing excellence within the broader Testronic network. The company has also added Lily Guerreiro to its senior leadership roster as Global Partnerships Senior Manager.
Guerreiro’s background includes a tenure as Global Business Development Manager at Keywords Studios, where she was responsible for cultivating and managing relationships with multinational clients across multiple continents. In her new role, she will focus on scaling Testronic’s partnership model, ensuring that the firm’s service offerings remain aligned with the fast‑changing demands of the gaming and interactive entertainment sectors. Turning to Asia, Testronic’s Centre of Excellence in Manila has seen two key senior appointments. Daniel Bowie Soriano joins as Senior QA Manager, bringing extensive hands‑on testing experience and a track record of leading large‑scale QA projects.
Working alongside him is Ivan Balanay, who takes on the role of QA Trainer. Balanay’s appointment is described by the company as a critical component of its investment in the Testronic Academy, an internal training initiative aimed at developing the next generation of QA professionals.
By bolstering the academy’s instructional capacity, Testronic aims to ensure a pipeline of highly skilled testers equipped with the latest methodologies and tools. Chief Revenue Officer Michael Fitzgerald, who announced these appointments, emphasized the strategic significance of the company’s geographically dispersed Centres of Excellence. "Our Centres of Excellence bring together talented people, specialist expertise and leadership, and connect those capabilities across a genuinely global organisation," Fitzgerald said.
He added that the recent investments in New Orleans, Warsaw, and Manila, in conjunction with the firm’s established presence in London, serve to deepen the pool of expertise available to partners. "By continuing to invest in outstanding people, we can deliver an exceptional Player‑Focused, Partner‑First and Outcomes‑Led service to our clients," he asserted.
These leadership changes come on the heels of a broader executive reshuffle earlier in the month, when Testronic announced the appointment of Sonia Kerr as Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. In the same announcement, Michael Fitzgerald was confirmed as CRO, and Samantha Williams was named Chief Commercial Officer.
Fitzgerald’s background includes a client partnership role at Keywords Studios, while Williams previously served as Testronic’s global CRO and head of Europe, bringing deep commercial acumen to the senior team. Collectively, these appointments signal Testronic’s aggressive strategy to reinforce its leadership talent across key markets, enhance its service delivery framework, and sustain its growth trajectory in the highly competitive quality assurance landscape.
By integrating seasoned professionals with proven track records in client partnership, business development, and quality management, the company aims to provide a seamless, high‑quality testing experience that meets the evolving expectations of game developers and publishers worldwide.
