Meta Infrastructure Chief Santosh Janardhan to Step Down as Dave Brown Takes Over
Meta is preparing for a major leadership change. Santosh Janardhan, its longtime head of infrastructure and co-head of engineering, is getting ready to step down from his current position in early 2027.
The move ends an important chapter for an executive who has spent more than 17 years helping build the technical infrastructure behind some of the world's most widely used social media platforms.
The company has named Dave Brown, a former Amazon Web Services (AWS) executive who joined Meta earlier this year, as the successor to Santosh Janardhan.
According to TechCrunch's report, Santosh Janardhan will stay involved during the transition. He will then move into an advisory role with Meta Compute, the company's initiative focused on expanding its computing infrastructure.
The change comes at a very important time for Meta. The company continues to invest heavily in artificial intelligence (AI), data centres and the computing capacity needed to support its growing technology plans. For Santosh Janardhan, the move marks a shift away from the day-to-day running of that infrastructure.
Who Is Santosh Janardhan, Meta's Departing Infrastructure Chief?
Janardhan joined Facebook, now Meta, in 2009. Over the years, he became one of the key executives responsible for developing and managing the infrastructure that supports the company's products and services.
His responsibilities extended beyond maintaining the systems behind Facebook and Instagram. They also involved the data centres, networks, computing hardware and other technical resources required to keep Meta's services running at a global scale.
As Meta expanded its operations, infrastructure became increasingly important to its ability to serve billions of users across Facebook, Instagram, WhatsApp and Threads.
Janardhan also played a role in the company's custom silicon and AI infrastructure efforts. He helped develop the computing power needed for its growing artificial intelligence operations.
In January 2026, he took on additional responsibilities as a co-lead of Meta Compute, an initiative created to coordinate the company's long-term computing strategy.
Although Meta has confirmed the leadership transition, neither the company nor the available reports have established a specific reason for Janardhan's departure. Bloomberg reported that his internal memo did not provide an explanation.
Dave Brown to Take Over Meta's Infrastructure Operations
With Janardhan preparing to hand over leadership, Dave Brown will assume responsibility for Meta's infrastructure organisation.
Brown joined Meta earlier in 2026 as vice president of infrastructure after spending approximately 19 years at Amazon. During his time at AWS, he worked across computing, cloud infrastructure and artificial intelligence services. His experience in these areas comes as vital to Meta's current priorities.
The appointment also reflects the growing importance of cloud computing and large-scale infrastructure expertise in the technology industry. Meta's services depend on enormous computing resources, while its expanding AI ambitions require even more processing capacity, specialised hardware and data centre investment.
Brown's experience at AWS could therefore prove valuable as Meta continues to develop the systems supporting its products and AI initiatives.
According to reports, Janardhan will support the transition through the first quarter of 2027 before moving into an advisory capacity connected to Meta Compute.
The Essence of Meta's Infrastructure Leadership
For many users, Meta is primarily associated with social media applications such as Facebook, Instagram, WhatsApp. The company, however, operates far beyond the applications people access on their smartphones. Behind these platforms is an extensive network of data centres, servers, storage systems, networking equipment and specialised processors responsible for handling enormous volumes of information.
Every time someone uploads a photograph to Instagram, sends a message through WhatsApp or interacts with Meta AI, computing infrastructure helps to process that activity.
The demands are becoming even greater as Meta expands its artificial intelligence operations. In an October 2026 publication, the company discussed how data centres support its AI strategy. Janardhan himself explained why infrastructure matters for building and deploying advanced AI technologies. Meta has also continued to invest in custom processors and partnerships with technology companies to expand its computing capabilities. An example is its partnership with Arm, which involves developing new processors for data centres and large-scale AI deployments. This makes the infrastructure department one of growing importance to Meta's long-term competitiveness.

Meta's AI Ambitions Are Changing Its Infrastructure Priorities
The leadership transition is happening as major technology companies compete to build the infrastructure needed for rapidly evolving, sophisticated AI systems.
Meta is among the companies investing heavily in this area, with data centres and computing resources becoming a core to its plans. The company has been expanding its AI-optimised data centre operations while exploring different ways to obtain the computing capacity required for its models and services. It has also worked with external partners, including AWS, to diversify its computing resources.
In April 2026, Meta announced an agreement to bring tens of millions of AWS Graviton processor cores into its computing portfolio. The partnership was intended to support the growing requirements of the company for agentic AI and other computing workloads. These developments demonstrate that Meta's infrastructure strategy is no longer limited to keeping existing social media platforms operational. It is steadily becoming tied to the company's ability to compete in the fast-developing AI market.
For this reason among others, the appointment of a new infrastructure chief is an important leadership development. Even so, Meta has not said that the transition will bring an immediate change to its overall strategy.

What Happens Next?
Janardhan's departure from the infrastructure leadership position will place greater responsibility on Brown as Meta continues to expand the frontiers of its technical operations. The transition will also be worth watching because of the scale of the company's ongoing investments in AI and data centre infrastructure.
Much has been speculated and there is plenty of optimism. Even so, it is too early to conclude that the leadership change will bring major operational or strategic changes. The confirmed developments are as follows:
- Janardhan is preparing to hand over his infrastructure responsibilities
- Brown is set to succeed him
- Janardhan will remain involved during the transition
Meta continues to compete with other technology giants in artificial intelligence. Its infrastructure leadership will remain central to how well it can manage and scale the computing systems behind its (grand) ambitions.
