Job description

Arcesium is a global financial technology firm that solves complex data-driven challenges faced by some of the world’s most sophisticated financial institutions. We constantly innovate our platform and capabilities to meet tomorrow’s challenges, anticipate the risks our clients encounter, and design advanced solutions to help our clients achieve transformational business outcomes.

Financial technology is a high-growth industry as change and innovation continue to disrupt the status-quo and prompt major transformation. Arcesium is at a particularly interesting time in our own growth as we look to leverage our successfully established market position and expand operations in pursuit of strategic new business opportunities. We value intellectual curiosity, proactive ownership, and collaboration with colleagues, and we empower you to meaningfully contribute from day one and accelerate your professional development.

About the Role and the Team

Arcesium seeks an exceptional engineer to join our Infrastructure team and provide expert-level technical leadership for our front-office Portfolio and Order Management System recently integrated into the Arcesium product suite.

This is a hands-on individual contributor role that owns the architectural direction for our most complex site reliability challenges and will be responsible for:

• Reliability, scalability, and operational maturity of a Kubernetes-native, AWS-hosted platform.
• High availability, disaster recovery, observability across components and client pods
• Troubleshooting live production issues with a deep focus on rapid incident resolution, creating RCA and building tools that enhance system stability and resilience.
• Bringing strong opinions on how infrastructure should be run - backed by experience running large-scale production systems.

What You Will Do

• Own the reliability and availability of core platform infrastructure including Kubernetes clusters, ArgoCD deployments, PostgreSQL databases, and supporting AWS services
• Plan and execute infrastructure maintenance - upgrades, patching, and validation of platform components with zero-to-minimal client impact
• Improve CI/CD pipelines and developer tooling, including migration of locally executed Terraform apply processes to automated, auditable workflows
• Build and enhance infrastructure monitoring, alerting, and observability to reduce mean time to detection and resolution
• Evaluate and adopt new infrastructure tooling and capabilities (service mesh, cost optimization, capacity planning) that improve reliability and scalability.
• Contribute to the convergence of Limina infrastructure with Arcesium's broader infrastructure ecosystem, supporting standardization of tooling, networking, security, and operational best practices
• Establish and participate in on-call rotations, building sustainable operational coverage across global time zones as the client base grows
• Troubleshoot and resolve complex cross-system issues spanning application, infrastructure, and cloud layers
• Write and review infrastructure-as-code, automation scripts, and internal tooling
• Lead by example with exemplary code, design documents, RFC's, runbooks, system and architecture design documents and documenting operational procedures to build institutional knowledge

What You Will Need

• A bachelor’s or master’s degree in computer science, Engineering, or a related field with 9+ years of professional engineering experience, including significant time in a principal-level or equivalent individual contributor role.
• Hands-on experience in site reliability engineering, infrastructure engineering, DevOps, or platform engineering roles
• Strong track record of owning and operating production Kubernetes environments (cluster lifecycle, networking, storage, RBAC, troubleshooting)
• Hands-on experience running critical workloads on AWS (EC2, EKS, RDS, IAM, VPC, S3, CloudWatch, and related services)
• Experience with observability platforms (Datadog, Prometheus, Grafana, ELK), modern alerting design, infrastructure-as-code (Terraform, CloudFormation), and CI/CD pipelines (GitLab CI, Jenkins).
• Strong programming and scripting ability in Python; familiarity with Bash, Go, or Java is a plus
• Experience with GitOps-based deployment workflows (ArgoCD, FluxCD, or similar)
• Familiarity with PostgreSQL or similar relational databases in a production context - backup, recovery, upgrades, and performance tuning
• Demonstrated experience with on-call rotations, incident management, and post-incident review processes
• A proven track record designing and delivering large-scale reliability initiatives (HA/DR, observability, automation platforms) with measurable outcomes.
