Full job description

At Semperis, our mission is to be a Force for Good. Starting with being a great place to work. We believe that when people feel valued, supported, and empowered, they do their best work. That’s why we focus on creating an employee experience rooted in purpose, growth, and balance. Semperis has been recognized as one of America’s Fastest-Growing Cybersecurity Companies by the Inc. 5000, a DUNS 100 Top Startup to Work For, and a multi-year Inc. Best Workplace awardee.

About the Role

We are seeking an exceptional Junior Engineer to join our Platform Group, where you will architect and develop shared infrastructure components that power Semperis's enterprise security and identity products. This is a highly collaborative role requiring both technical excellence and strong cross-functional partnership skills.

What You'll Do

As a Junior Software Engineer on our Core Platform team, you will:

Design and build shared platform components used across multiple product teams, ensuring scalability, reliability, and maintainability
Architect distributed systems using microservices and event-driven patterns that support enterprise-scale workloads
Own critical backend services from conception through deployment, including code quality, performance optimization, and operational excellence
Collaborate extensively with product engineers, DevOps, and architects to define platform capabilities and technical standards
Drive technical initiatives that improve developer productivity, system observability, and platform resilience
Contribute to architectural decisions and establish best practices for backend development across the organization
Analyze system performance and data patterns to identify optimization opportunities and inform future platform investments

What You Bring

Required Qualifications

1+ years of professional software engineering experience, with expertise in backend development
Working proficiency in C# and .NET Core, including modern framework features and performance optimization
Production experience with Kubernetes and container orchestration in cloud environments (Azure/AWS/GCP preferred)
Experience developing shared libraries, frameworks, or platform components consumed by multiple teams
Demonstrated ability building enterprise SaaS applications serving high-volume, multi-tenant environments
Strong collaborative mindset with excellent communication skills and experience working across teams to drive consensus
Bachelor's degree in Computer Science or equivalent practical experience
Fluency in English (written and verbal)

Preferred Qualifications

Experience in the Enterprise Identity and Access Management (IAM) domain
Hands-on expertise with Kafka, RabbitMQ, or similar message brokers
Knowledge of ElasticSearch or other distributed search/analytics platforms
Open-source contributions or experience maintaining shared component libraries
Experience with observability tools (Prometheus, Grafana, distributed tracing)
Background in API design and governance for platform services
Familiarity with CI/CD pipelines and infrastructure-as-code practices

Why Join Semperis?
You’ll be part of a global team on the front lines of cybersecurity innovation. At Semperis, we celebrate curiosity, integrity, and people who take initiative. If you’re someone who sees the glass as half full, embraces challenges as growth opportunities, and values a healthy balance between work and life—we’d love to meet you.

**Semperis maintains office locations in several cities across the globe. Candidates who reside within 45 miles of one of our offices—or where the job description specifies a required location—will follow our hybrid work model. This includes working onsite some days per week and remotely the remaining days.
