Overview

We are looking for a Senior Software Engineer to join the Identity Manager development team at One Identity. In this role, you will play a key part in shaping and evolving our enterprise-grade Identity Governance and Administration (IGA) platform — contributing not just to infrastructure, but to the software that runs on it.

This is a hybrid engineering role for someone who is equally comfortable writing production C# code as they are managing Kubernetes clusters. You will bridge the gap between platform engineering and application development, ensuring our containerized infrastructure and the services it hosts are secure, scalable, and built to last.

Responsibilities

Platform & Infrastructure

Design, build, and operate a secure, scalable Kubernetes-based platform across cloud and/or on-premises environments

Own the full containerization lifecycle — Docker image authoring, optimization, registry management, and security hardening

Provision and manage Kubernetes clusters with a focus on high availability, scalability, and production stability

Develop and maintain Kubernetes resources (Deployments, StatefulSets, DaemonSets, Services, Ingress, ConfigMaps, Secrets) and Helm charts for standardized deployments

Implement and enforce RBAC and cluster security hardening standards

Architect and maintain CI/CD pipelines for containerized workloads using GitOps practices and IaC

Build and maintain observability solutions — monitoring, logging, alerting — and lead incident response and root cause analysis

Application Development

Design and implement backend services and platform tooling in C#/.NET

Develop and maintain integrations, internal APIs, and automation tooling that supports platform operations and developer workflows

Work with relational databases (e.g., SQL Server, PostgreSQL) — including schema design, query optimization, and data migration strategies

Collaborate with development teams to improve platform reliability and developer experience, contributing code where it matters most

Write clean, maintainable, and well-tested code in alignment with engineering standards

Qualifications

Platform Engineering

Deep knowledge of Kubernetes architecture, core components, and cluster management (cloud or on-prem)

Hands-on experience with Docker and writing optimized Dockerfiles

Experience with managed Kubernetes services (Amazon EKS, GKE, or AKS)

Solid understanding of cloud networking fundamentals (VPCs, load balancers, DNS)

Experience with IaC tools such as Terraform or CloudFormation

Hands-on experience designing CI/CD pipelines using tools such as Jenkins, GitHub Actions, GitLab CI, ArgoCD, or Flux

Experience with monitoring and logging solutions (Prometheus, Grafana, ELK Stack)

Solid Linux system administration skills

Software Development

Proficiency in C#/.NET with experience building backend services or platform tooling in a production environment

Strong working knowledge of relational databases — query writing, schema design, indexing, and performance tuning (SQL Server and/or PostgreSQL preferred)

Experience writing automation scripts and integrating with REST APIs

Familiarity with software development best practices: version control, code review, testing, and CI/CD

Soft Skills & Ways of Working

Systems thinking and a structured troubleshooting mindset

Strong ownership mentality — you treat infrastructure and code reliability as your responsibility

Clear documentation habits and cross-team collaboration skills (Dev, QA, Security, Ops)

Confident English proficiency, written and spoken
