Valarian Technologies is a dual‑use technology company building critical tools to safeguard the future in an era of evolving global security challenges. We’re rethinking security beyond traditional military domains, addressing asymmetric threats that impact our technological advantage, economic strength, and democratic institutions.
We build Acra – the platform foundation for everything we do as a dual‑use technology company. The platform’s name, rooted in the Greek word for citadel (or fortress), reflects the design and purpose of our infrastructure‑agnostic secure enclaves: protecting critical data. Some of the government and commercial workflows include increased operational resiliency for mission‑critical systems, enabling organizations to more quickly and widely adopt emerging technologies while ensuring the integrity of their intellectual property; information flow during disaster response scenarios; and zero‑trust / least‑privilege environments for M&A, attorney‑client privileged communications, etc.
The Role
You will help design, build, and operate backend services for a complex platform that needs to be secure, reliable, observable, and scalable from the start.
- Build backend services, APIs, and microservices in Go.
- Contribute to the design, implementation, testing, deployment, and operation of backend services.
- Build and maintain Docker images, Kubernetes workloads, CI/CD pipelines, and Argo/GitOps workflows.
- Work with container registries, secrets, secure configuration, and deployment automation.
- Help design event‑driven, scalable, observable, and resilient systems.
- Contribute to platform architecture, system design discussions, and security boundaries.
- Support identity‑aware service communication, lifecycle orchestration, auditability, and controlled application execution.
- Help improve monitoring, logging, tracing, alerting, and production debugging.
- Work closely with product and the engineering team to turn requirements into reliable technical solutions.
- Take ownership of well‑defined projects and contribute independently within a collaborative engineering team.
- Operate comfortably in a startup environment where engineers work across backend, platform, and DevOps responsibilities.
What we are looking for:
- Solid 5-6 years backend engineering experience.
- Hands‑on Go experience.
- Experience building APIs, backend services, or microservices.
- Comfortable working with Docker and containerised applications.
- Some experience with Kubernetes, or a strong interest in working deeply with Kubernetes‑based systems.
- Understanding of CI/CD pipelines and modern deployment workflows.
- Familiarity with GitOps, Argo, container registries, secrets, or secure deployments.
- Understanding of event‑driven architecture, asynchronous workflows, or distributed systems.
- Good system design fundamentals, especially around reliability, scalability, observability, and failure handling.
- Comfortable debugging issues across applications, services, and infrastructure.
- Product‑minded and interested in understanding why the platform is being built, not just what needs to be implemented.
- Self‑driven, curious, and able to take ownership of defined areas of work.
- Comfortable working in a startup environment with changing priorities and broad technical exposure.
- Willing to learn across backend, platform, infrastructure, and DevOps areas.
Nice to have:
- Experience with secure or regulated environments, such as defence, government, fintech, healthcare, critical infrastructure, or sovereign cloud.
- Experience working in startups, platform teams, infrastructure teams, or product teams with broad engineering ownership.
- Understanding of zero‑trust architecture, identity‑aware systems, policy enforcement, or workload isolation.
- Experience with service mesh, network policy, ingress/egress control, or secure service‑to‑service communication.
- Experience with observability tooling, including metrics, logs, traces, alerting, and incident response.
- Familiarity with supply‑chain security concepts such as image signing, vulnerability scanning, SBOMs, artifact verification, or admission control.
- Familiarity with secrets management tools such as Vault, SOPS, Sealed Secrets, External Secrets, or cloud‑native secret managers.
- Experience contributing to systems where auditability, traceability, and operational evidence are important.
Benefits:
- Equity – because you have the right to own what you’re building.
- A competitive salary – because we value your unique skills.
- Employer pension contributions – because you deserve a secure future.
- Hybrid work setup – because everyone has different needs.
- Rewarding company retreats and meetups that respect your work/life balance – because we love getting to know each other!
