Welcome Jake Marwil

We’re excited to welcome Jake to Dfns as a Senior Infrastructure Engineer. Jake joins us with over a decade of experience building and operating large-scale, production infrastructure across cloud platforms, fintech, and crypto. His background sits exactly at the intersection we care about most: reliability, developer tooling, and systems that have to work under real-world constraints.

From cloud infrastructure to crypto production systems

Jake most recently worked at Gemini, where he spent nearly four years as a Site Reliability Engineer, including over a year as a Senior SRE. At Gemini, he focused on maintaining and scaling critical infrastructure supporting a global crypto exchange, systems that require high availability, strict operational discipline, and the ability to handle continuous load. His work covered incident response, system reliability, and production operations across distributed environments.

Before that, Jake was a Senior Platform Engineer at Pager, where he helped design and operate cloud-native infrastructure at scale. He played a key role in building deployment systems and improving developer workflows, including leading the transition to Spinnaker-based deployments and managing CI/CD pipelines across Kubernetes, Terraform, and Docker.

Earlier in his career, Jake worked at Oracle and IBM, where he contributed to large-scale cloud platforms and internal tooling systems. At IBM Bluemix, he operated and maintained dozens of cloud environments globally, building automation systems and deployment pipelines while handling on-call responsibilities for production systems.

Across these roles, a consistent theme emerges: Jake builds systems that are meant to run continuously, recover gracefully, and scale without introducing operational complexity.

Deep focus on reliability and developer experience

Jake’s experience goes beyond infrastructure in isolation. He has consistently worked on improving how engineers interact with infrastructure. He has built internal platforms to track service versions across environments, developed tooling to streamline deployment pipelines, and established processes that make systems easier to operate and reason about.

His stack spans modern infrastructure and observability systems, including Kubernetes, Terraform, Docker, and monitoring platforms such as Datadog, New Relic, and Sentry. He has also worked extensively on automation, writing scripts and services in Bash, Python, Ruby, and Go to reduce manual intervention and improve system resilience.

Strengthening Dfns’ infrastructure across four core challenges

At Dfns, infrastructure is not a support layer. It is the product. Every wallet, every transaction, and every policy decision depends on systems that must be secure, deterministic, and always available. As we scale across more blockchains, higher volumes, and more demanding institutional environments, the challenges become increasingly complex.

Jake joins us at a moment where we are pushing the limits of what wallet infrastructure needs to handle across four core dimensions.

1. DevOps, scalability, and performance: Dfns operates high-throughput systems that must handle continuous transaction flows across multiple chains. This requires strong control over deployment pipelines, infrastructure automation, and runtime performance. The goal is not just to scale, but to scale predictably, without introducing latency, bottlenecks, or operational overhead.
2. Security, zero trust, and data integrity: Security is foundational to everything we build. Our infrastructure enforces strict separation between key material, authentication, and execution layers. This requires a zero-trust architecture, hardened environments, and continuous guarantees around data integrity, auditability, and isolation.
3. Blockchain nodes and transaction reliability: Unlike traditional systems, blockchain infrastructure is inherently unreliable. Nodes can desync, RPCs can fail, and transactions can be dropped or behave inconsistently. Dfns addresses this by building a deterministic transaction layer on top of inherently non-deterministic systems. This requires deep control over node infrastructure, transaction lifecycle management, and continuous reconciliation of on-chain state.
4. On-prem deployments and maintainability: Dfns is deployed not only as a SaaS platform but also in controlled environments, including on-premise and hybrid setups for large institutions. This introduces a different class of challenges: reproducibility, upgradeability, and long-term maintainability across heterogeneous environments.

Jake will play a key role across all four areas, strengthening the systems that allow Dfns to operate reliably at scale while maintaining the level of security and control required by banks and financial institutions. This is not about building infrastructure that works in theory. It is about building infrastructure that holds under real-world conditions. We’re excited to have him on board.
