The posting

We are looking for a driven and design-minded Software Developer with experience in Java programming and a scripting language (Bash, Python, or Go), for our Rocky Linux based Fidelis cybersecurity platform and appliances. The ideal candidate has experience writing Java using Spring Boot and Hibernate/JPA, and strong SQL skills with relational databases.

Fidelis Security is a growth-oriented company that provides organizations with a robust, comprehensive portfolio of products, services, and expertise to combat today's sophisticated advanced threats and prevent data breaches. Our commercial enterprise and government customers around the globe can face advanced threats with confidence within our Network Defense and Forensics Services, delivered by an elite team of security professionals with decades of hands-on experience, and our award-winning Advanced Threat Defense Products, which provide visibility and control over the entire threat lifecycle.

As a Software Developer you will:

  • Develop and enhance cybersecurity platform services: design, implement, and maintain robust backend features and system components in Java (Spring Boot + Hibernate/JPA).
  • Build RESTful APIs and data flows; design schemas, manage migrations, and write efficient SQL for relational databases.
  • Write and maintain automation and tooling in Bash, Python, and/or Go for builds, deployments, diagnostics, and test harnesses.
  • Operate on Rocky Linux servers; troubleshoot across OS, networking, JVM, and database layers; daily development in IntelliJ or Eclipse.
  • Participate in peer code reviews, knowledge sharing, and SCRUM meetings; collaborate using the Agile software development lifecycle.
  • About 85–90% of the programming for this role is in Java and SQL; the rest is scripting (mostly Bash and Python/Go).

Requirements

  • Strong experience developing applications using Java, with a strong understanding of object-oriented programming principles (concurrency, collections).
  • Hands-on with Spring Boot and Hibernate/JPA.
  • Experience building RESTful APIs and writing unit/integration tests.
  • Strong SQL and data modeling; hands-on with relational databases (e.g., MariaDB, PostgreSQL, MySQL, etc.).
  • Knowledge of TCP/IP networking fundamentals.
  • Comfortable working in Linux (preferably Rocky/CentOS/RHEL): shell, system services, logs, performance troubleshooting.
  • Good scripting skills in Bash and Python (bonus: Go).
  • Working knowledge of Git and CI/CD practices; IDEs: IntelliJ or Eclipse.
  • BSCS or MSCS (or related technical field) with 5–6+ years of experience developing and supporting multithreaded applications in a Linux/Unix environment.

Bonus Skills

  • Linux networking tools (iptables, ipset, ebtables), routing/bridging/VLANs, and packet capture/analysis.
  • Active Directory integration experience (AD/LDAP/Kerberos), Windows domain concepts, service accounts/GPOs.
  • Cloud APIs: experience automating or integrating with AWS, Azure, Google Cloud, and/or OCI (SDKs/CLIs for compute, storage, networking, IAM).
  • vSphere/ESXi for VM lifecycle management (provisioning, snapshots, virtual networking).
  • VirtualBox experience, especially using the VBox CLI (vboxmanage) for automation.
  • Containerization & orchestration: Docker and Kubernetes; event streaming: Kafka.
  • Experience with Bitbucket or GitLab (repos, merge requests, CI pipelines, permissions).
  • Cybersecurity domain experience (threat detection, hardening, threat research).
  • Experience working on Agile software development projects.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
