Devops Engineer

Role & responsibilities

2. DevOps / Infrastructure Engineer

Build and run the cloud infrastructure behind a financial platform that has to stay up. You'll own infrastructure-as-code, Kubernetes, observability, and incident response for a system where downtime during volatility is the worst possible failure mode.

What You'll Do

- Design, build, and maintain cloud infrastructure on AWS (EC2, Lambda, EKS, VPC, IAM, and related services)

- Write and maintain all infrastructure as code using Terraform - no manual console changes in production

- Manage and scale Kubernetes (EKS) clusters and containerised workloads

- Design, deploy, and maintain database infrastructure - relational, NoSQL, and time-series - including HA, backups, and tested restores

- Build and maintain CI/CD pipelines for reliable, automated, auditable deployments

- Implement and operate monitoring, logging, and alerting (Prometheus, Grafana, Loki, Datadog), including latency and error-budget SLOs

- Own secrets management, key handling, and security hardening across environments

- Ensure high availability and disaster recovery - define and regularly test RTO/RPO targets

- Own infrastructure cost optimisation and capacity planning, including headroom for volatility-driven traffic spikes

- Set up and maintain incident management: alerting, escalation, on-call rotation, and blameless postmortems

- Support audit and regulatory requirements - log retention, access controls, and evidence collection

- Collaborate closely with backend engineering to support scalable, production-grade systems

Preferred candidate profile

What We're Looking For

- 5+ years of DevOps / infrastructure engineering experience

- Proven, hands-on track record writing and maintaining Terraform in production (mandatory)

- Strong experience with AWS: EC2, Lambda, EKS, VPC, IAM, and related services

- Solid experience operating production Kubernetes clusters

- Experience provisioning and managing database infrastructure at scale (MySQL, PostgreSQL, MongoDB; time-series a plus)

- Experience with observability stacks: Prometheus, Grafana, Loki, and Datadog

- Hands-on with secrets management (Vault, AWS Secrets Manager, or equivalent)

Strong understanding of networking, security, and high-availability system design

- Scripting proficiency (Bash, Python, or similar) for automation

- Experience with CI/CD tooling and GitOps practices

- On-call incident response experience in a production environment

Nice to Have

- Infrastructure experience for high-uptime, transaction-critical, or financial systems

- Familiarity with security hardening, compliance frameworks, and audit readiness (SOC 2, ISO 27001, CERT-In, or similar)

- Edge security: WAF, DDoS mitigation, bot management

- Key management / HSM or MPC-adjacent infrastructure

- Data pipeline and migration tooling, such as AWS DMS, Snowflake or similar

- Experience running blue/green or canary deployments for stateful services
