- Real experience with edge, WAF or reverse proxy technology: Envoy, nginx, Cloudflare, ModSecurity, Coraza or equivalent
- Production Kubernetes, ideally EKS, and strong Terraform
- Operating PostgreSQL at scale. You have done upgrades and performance work, not just connected to one
- Practical observability experience. You have built alerting that worked, and killed alerting that did not

- English at a working professional level. Our engineering team is international
Nice to have
- Search infrastructure: Typesense, Elasticsearch, OpenSearch or vector search
- Content protection and anti-scraping work
- Having supported ISO 27001, SOC 2 or similar audits from the technical side
- Healthcare, fintech or another regulated domain

Full description
Senior DevOps Engineer (Security and Reliability)Physitrack PLC · Fully remote, based in Poland Contract: B2B contractor, EUR 8,000 per month
About usPhysitrack PLC builds digital health software used by clinicians, physiotherapists and employers in over 100 countries. Our two product lines, Physitrack (exercise prescription, telehealth and patient engagement) and Champion Health (workplace wellbeing), run on a multi-region AWS platform serving Europe, the UK, North America, Australia and the Middle East.
We are ISO 27001:2022 certified. We hold clinical data and a large proprietary content library, and both need defending properly.**
The roleYou will own the security and reliability surface of our infrastructure: the edge, the data layer, and the observability stack that tells us when either is misbehaving. It sits where security engineering meets SRE. You will design controls at the edge, harden our cloud posture, make sure we can see what is happening across a multi-region estate, then evidence all of it to auditors and enterprise customers. This is hands-on engineering, not a governance role.
We are recruiting two senior infrastructure roles. This one covers the edge, observability and cloud security posture. The other, Senior DevOps Engineer (Platform), covers the Kubernetes estate, delivery pipelines and migrations. Apply for whichever fits, and tell us if both do.**
What you will doEdge and network security
- Own our Envoy based edge, along with WAF rules, rate limiting and bot management across our cloud and CDN layers
- Design and tune protections against abuse, including content scraping, credential attacks and traffic anomalies
- **Build detection for the traffic patterns that matter, and keep improving its signal to noise ratio
Cloud security posture
- Harden our AWS estate: IAM boundaries, least privilege access, threat detection and runtime monitoring on EKS
- Manage secrets, certificates and token lifecycle across the platform
- **Produce the infrastructure evidence behind ISO 27001 audits, penetration tests and enterprise security reviews
Data platform**
- Run PostgreSQL and RDS in production across regions, covering upgrades, performance, encryption and access control
- Own our search infrastructure, Typesense and vector search, end to end
- **Work with MongoDB and Elasticache alongside the primary data stores
Observability**
- Own the monitoring platform: Grafana, Loki and Prometheus, plus Sentry and PagerDuty
