[Hiring] Senior DevOps Engineer @Deciphex

Role Description

Every laboratory and customer site we work with depends on a secure, reliable connection into our platform. You will own that connectivity: the AWS infrastructure that links our products to laboratory and customer systems, and the secure network paths our research teams use to reach their compute. It supports a regulated clinical environment, so it must be secure, observable and recoverable.

You will report to the Principal Engineer - Cybersecurity & DevOps and join a lean team in which each engineer owns a defined area, with no large support structure.

What This Is NOT

• Not an IT, helpdesk or end-user support role.
• Not an infrastructure ticket-queue role.
• Not a product CI/CD ownership role. The DevOps team owns it, and you contribute as part of that team.
• Not a role with hand-built servers. If it cannot be rebuilt from code, it is not finished.

About our DTO Team

Our Digital Trust & Transformation Office (DTO) brings together the teams that keep Deciphex trustworthy and moving forward:

• Information security
• Cybersecurity
• Application security
• DevOps
• IT
• Data protection and privacy
• AI and AI governance
• Operational resilience

We work to one aim: our customers, clinicians and patients can trust our systems and the data in them, and our engineers can ship safely and quickly.

Our Technology stack

• AWS
• GCP
• Terraform
• Helm
• Docker
• Mirth
• Linux/Win/cloud networking/firewalling

What You help us with

• Work as part of a lean DevOps team.
• Own the connectivity to on-premises laboratory applications.
• Own the secure network access to research and data science platforms.
• Implement security standards set by Cybersecurity and Data Security engineers.
• Set technical direction and make design decisions.
• Run and scale customer connectivity services on EKS, with monitoring, firewall rules and certificates.
• Provide connectivity, network policy and secrets as code (Terraform and Helm).
• Operate and upgrade cloud-hosted integration and laboratory platform services with high availability and backup.
• Run disaster-recovery exercises and keep the evidence.
• Own secure network access to GPU and research compute across cloud providers.
• Shape the shared network and connectivity layer of our AWS multi-account platform (landing zone).
• Build monitoring, flow-log analysis and alerting systems.
• Patch and harden the cluster, nodes and images following security standards.
• Document the estate as code.
• Join the on-call rota (planned changes happen outside laboratory hours).
• Mentor colleagues.

What You Bring

• 5/6++ years in DevOps, SRE or infrastructure engineering.
• Experience owning and debugging in production.
• Deep Linux/Win networking knowledge: iptables / nftables, routing, DNS and TLS.
• Experience with site-to-site VPN and private connectivity (IPsec, WireGuard or OpenVPN).
• Production experience with Kubernetes, ideally Amazon EKS.
• Infrastructure as code experience, ideally Terraform (or OpenTofu).
• AWS administration skills at the level of trust to change VPCs, endpoints, RDS and IAM safely.
• Disciplined production change practices: peer review, monitoring, runbooks and tested recovery.
• Knowledge and experience with both Windows and Linux networking, CI/CD, secrets management and SSO or federation.
• Experience with cloud-based healthcare integration (e.g., HL7 or FHIR) is a plus.

What Success Looks Like

• Cloud connectivity for new customers, internal teams or laboratories is provided as code, through a predictable process, and documented.
• Faults are identified by monitoring before laboratory staff or customers report them.
• Recovery is tested regularly, with evidence.
