Testronic has announced a series of high‑level appointments across its worldwide operations, underscoring the company’s commitment to expanding its leadership bench and deepening its service capabilities. Among the most notable additions is Mike Guttman, who has been named Vice President of Senior Partnerships.
In this role, Guttman will oversee the cultivation of strategic relationships with Testronic’s most important clients, ensuring that the firm’s testing and quality‑assurance solutions remain closely aligned with the evolving needs of the gaming and interactive entertainment sectors. Guttman brings a wealth of experience to Testronic. Prior to joining, he spent several years at Keywords Studios, where he served as a client partner, directly managing large‑scale accounts and driving revenue growth through consultative selling. Before that, he held a senior business‑development position that sharpened his ability to identify market opportunities and forge long‑lasting partnerships.
His track record of delivering measurable results in high‑pressure environments makes him a natural fit for the senior‑partnerships portfolio at Testronic. 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 previously worked at Keywords Studios as an enterprise account executive, where she managed complex, multi‑year contracts for major studios. Her experience also includes a tenure at Unity, where she served as senior account executive for the Parsec and SyncSketch platforms, giving her deep insight into the workflows and technical requirements of modern game development pipelines.
Together, Guttman and Closson form a dynamic duo aimed at strengthening Testronic’s market presence and delivering tailored solutions to a diverse client base. In the European hub of Warsaw, Testronic has elevated Mateusz Kałuża to the position of QA Director. Kałuża arrives with a robust background in quality assurance, having held senior testing roles at Lionbridge Games. He emphasizes the strategic importance of Warsaw as a centre of QA excellence, noting, "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." His leadership is expected to harmonize local talent with the broader Testronic network, fostering a seamless delivery model that can scale across borders. Further reinforcing the global partnership agenda, Lily Guerreiro joins the executive ranks as Global Partnerships Senior Manager.
Guerreiro previously held the role of Global Business Development Manager at Keywords Studios, where she was responsible for expanding the company’s footprint in emerging markets and nurturing high‑value client relationships. Her expertise in navigating cross‑cultural negotiations and her deep understanding of the gaming ecosystem will be instrumental in driving Testronic’s partnership strategy on a worldwide scale. The Manila Centre of Excellence, a cornerstone of Testronic’s operational model, also welcomes two senior figures.
Daniel Bowie Soriano steps in as Senior QA Manager, bringing a seasoned perspective on test planning, execution, and quality metrics. Alongside him, Ivan Balanay takes on the role of QA Trainer, a position that directly supports the company’s investment in the Testronic Academy—a training program designed to cultivate the next generation of QA professionals. Balanay’s appointment is described as a move that "further supports [its] investment in developing the Testronic Academy and building the next generation of QA expertise," highlighting the firm’s dedication to continuous learning and skill development.
Chief Revenue Officer Michael Fitzgerald commented on the broader strategic context of these appointments, 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." Fitzgerald’s remarks underscore the company’s philosophy of leveraging geographic diversity to create a resilient, high‑performing service network.
These leadership changes follow a recent reshuffle at the very top of Testronic’s hierarchy. Earlier this month, Sonia Kerr was appointed Chief Executive Officer, succeeding Sharon Baylay‑Bell, who transitioned to the role of company chair. In tandem with Kerr’s promotion, 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 Europe, bringing a deep familiarity with the company’s commercial operations.
Collectively, these appointments signal Testronic’s aggressive pursuit of growth and excellence across its global footprint. By integrating seasoned professionals from industry leaders such as Keywords Studios, Unity, and Lionbridge Games, the company is positioning itself to offer more sophisticated testing solutions, faster turnaround times, and a higher degree of strategic alignment with its partners. The expanded leadership team is expected to drive innovation in QA methodologies, enhance client engagement, and reinforce Testronic’s reputation as a trusted partner for developers seeking to deliver polished, player‑centric experiences.
In summary, Testronic’s recent senior hires across New Orleans, Warsaw, Manila, and its London headquarters reflect a deliberate strategy to deepen expertise, broaden market reach, and cultivate a culture of continuous improvement. With Mike Guttman at the helm of senior partnerships, supported by a robust cadre of business development and QA leaders, the company is well‑poised to meet the rising demand for high‑quality testing services in an increasingly competitive gaming landscape.
