Software Engineer - Infrastructure

Blend is solving significant internal engineering challenges as we expand from processing thousands to millions of loans, at more and more lending organizations, and over an increasingly large part of the lifecycle of each loan. We're looking for engineers who are passionate about automation, scale, performance, security, and clean code.

Blend's Infrastructure team acts as a company within a company; empowering developers to ship their code faster and more securely. The work the team does is incredibly important and multiplies productivity across the entire organization. We’re looking for a Software Engineer with a deep focus on infrastructure and platform engineering to join our team. This role is ideal for someone who thrives in building Kubernetes at scale, internal platforms, and developing tools that enable developer velocity and operational excellence. This is not a traditional DevOps role — it’s a software engineering position that embraces DevOps principles and infrastructure best practices to create resilient systems and empower teams.

• Operate Kubernetes infrastructure (EKS) at scale, supporting dynamic provisioning, intelligent autoscaling, and secure multi-tenant workloads.
• Maintain and enhance our internal developer platform and tooling (built in Go on top of Kubernetes) to automate deployments, configuration, and infrastructure workflows — improving deployment orchestration self-service capabilities.
• Plan and perform zero-downtime Kubernetes upgrades, ensuring compatibility and minimizing disruption across hundreds of services.
• Develop Infrastructure-As-Code using Terraform for provisioning and operating infrastructure in reliable and repeatable fashion.
• Drive improvements across our AWS infrastructure in areas like networking, IAM, cost optimization and monitoring.
• Participate in a 24x7 on-call rotation and be an escalation contact for service incidents.

• You have a Bachelor's degree in Computer Science, Engineering, or a related field with 5+ years of Platform / SRE / Infrastructure experience. 
• Proficient in one major programming language such as Go (preferred), Typescript/Node.js, Python, Rust, C++, etc.
• Proven track record of shipping and maintaining internal platforms / tooling or developer infrastructure used at scale.
• Deep knowledge of at least one major cloud provider (AWS preferred).
• Shown ability with configuration management and service orchestration tools such as Terraform, Kubernetes, and Docker (EKS preferred).
