Description
Systems Developer - Email Security
As a Systems Developer in the Email Security Team, you will build and operate a highly scalable, globally deployed email security solution. This is a builder-operator hybrid role: you will design, implement, deploy, and maintain the components you create, from initial concept through production operations.
You will be part of the core team developing email services for customer base. Your work will include:
Developing filtering plugins, internal tools, and management infrastructure
Integrating third-party products (open source such as Postfix, or OEM components like proprietary malware engines) into our Linux-based and cloud stacks
Building and maintaining public APIs for email processing and configuration
Extending monitoring, alerting, and log aggregation capabilities
Troubleshooting and debugging production systems
Life-cycle management and optimization of existing deployments, including cloud-native environments
You will own your components end-to-end. Operational excellence matters as much as code quality.
This role is not a fit if you are looking for : a pure software development position where someone else handles deployment and operations, or a system administration role focused on configuration and support rather than development.
We value both specializations. This role simply requires solid foundations of both areas in one person.
Required Qualifications
Higher education (ETH, university, FH ) in Computer Science or a related field
2+ years of professional experience in a relevant role
Proficiency in software development with scripting languages (e.g., Bash, Perl, Python) and a concurrent compiled language (e.g., Go, C++, C#, Rust)
Experience with Linux or another UNIX-based operating system, including comfort working at the system level
Knowledge of email protocols and security standards: SMTP, TLS, DNS, DKIM , DMARC
Familiarity with software and system testing practices
Understanding of monitoring and observability principles
Fluent in English
Clear communication skills and ability to work both in a team and independently
Nice to Have
Familiarity with proprietary email backends such as Microsoft 365
Experience using LLM-assisted development tools
Knowledge of container and cloud technologies (Kubernetes)
Experience with general network protocols (TCP/IP, HTTP)
In addition to your work in a Development team, you will become certified as a Mission Control Engineer, providing you with knowledge in a wide area covering networking and security topics. This will give you the opportunity to visit our Network Operations Centers in Honolulu, Hawaii for 3-month deployments.
