Senior Infrastructure Engineer (Core Infra)
Responsibilities
We are looking for a Senior+ Platform Infrastructure Engineer who thrives in a highly autonomous environment and enjoys taking ownership of complex technical challenges.
Our Platform Infrastructure team is responsible for the foundation that powers all production services. While the team's structure continues to evolve as we grow, its core responsibilities are well established. You'll have the opportunity to influence technical direction, improve platform reliability, and help shape future infrastructure initiatives.
This role is best suited for engineers who enjoy solving problems across multiple infrastructure domains rather than focusing on a single specialization.
You will do:
Design, build, and operate scalable infrastructure and platform services.
Improve platform reliability through monitoring, alerting, incident management, and operational excellence.
Develop and maintain our Kubernetes-based compute platform.
Work with AWS production infrastructure, including compute, networking, and load balancing.
Build and enhance observability solutions (monitoring, logging, tracing, alerting).
Participate in security and compliance initiatives, including vulnerability remediation and infrastructure hardening.
Support onboarding of new services and facilitate their transition between engineering teams.
Own projects end-to-end from identifying dependencies and coordinating with stakeholders to successful delivery.
Drive improvements that reduce operational overhead through automation and better platform design.
Participate in production releases and on-call rotations.
Engineers may have opportunities to move between infrastructure teams based on business needs and personal interests, allowing exposure to different technical domains over time.
What We're Looking For
Required Qualifications
Extensive experience as a Senior Platform Engineer, Infrastructure Engineer, or Site Reliability Engineer.
Strong sense of ownership and ability to work independently with minimal supervision.
Ability to identify problems, define priorities, and drive initiatives without waiting for detailed instructions.
Broad infrastructure background with experience across multiple domains rather than deep specialization in only one area.
Strong understanding of Linux internals, including:
Virtual memory
Process resource management
cgroups
Hands-on experience with:
Kubernetes
Distributed systems
AWS production infrastructure (EC2, VPC, Load Balancers, etc.)
Networking fundamentals
Proven ability to deliver complex technical initiatives from concept to production.
Requirements
Qualifications / Experience / Technical Skills / Soft Skills
10+ years of experience in infrastructure or systems engineering roles.
Proven expertise in distributed systems and cloud-native architectures.
Strong understanding of Linux internals, including networking and system-level performance tuning.
Experience operating infrastructure on AWS at scale.
Proficiency with Terraform and Kubernetes.
Solid understanding of network security and cloud security best practices.
Excellent analytical, troubleshooting, and communication skills.
Nice to Have
Experience with one or more of the following:
Infrastructure security and compliance
Vulnerability management and security hardening
Identity and access management
Firewall configuration and privilege management
Compliance frameworks and interpreting security requirements
Observability platforms, monitoring, logging, and alerting
Database infrastructure and performance troubleshooting
CI/CD pipelines and deployment automation
Release engineering
What Makes You Successful
We're looking for someone who:
Works effectively without micromanagement.
Takes responsibility for technical decisions and can clearly justify design choices.
Pays close attention to detail, especially when working on security-sensitive systems.
Thinks beyond immediate fixes and strives to reduce long-term operational burden.
Collaborates effectively across engineering teams to unblock dependencies and deliver results.
Is comfortable working across multiple areas of infrastructure and continuously learning new technologies.
Why Join Us?
Work on infrastructure that powers production at scale.
Influence architectural decisions and long-term platform strategy.
Solve complex engineering challenges across infrastructure, Kubernetes, reliability, security, and cloud platforms.
Enjoy a high level of autonomy, trust, and technical ownership.
Grow across different infrastructure domains as the platform and team continue to evolve.
