Senior DevOps Engineer (Kubernetes) - Levi9

JOIN OUR DEVOPS ENGINEERING TEAM

At Levi Nine we are passionate about what we do. We love our work and together in a team we are smarter and stronger. We work in a dynamic and challenging environment with talented and forward-thinking people who are part of creative and innovative teams. We are looking for skilled team players who make change happen. Are you one of these players?

PROJECT DESCRIPTION:

Our partner is a global leader in the domain of clearing, offering access to a wide range of listed instruments on markets across the globe.

IT is at the heart of their organization with more than 30 different product teams and 10 different platform teams that are trying to build the best products & services for their customers.

Their presence in important financial centers like Amsterdam, Chicago, Sydney, Singapore, Tokyo Hong Kong, London, Sao Paulo, Frankfurt and Iasi, allows them to effectively serve clients worldwide and maintain close proximity to their diverse customer base.

THE ROLE INVOLVES:

Our partner is modernizing and migrating its next generation risk and margining systems.

These systems are high performance, low latency, C++ services that process large volumes of market, position, and collateral data.

For this we are looking for a DevOps Engineer who can strengthen their engineering platform, automate deployments, and improve reliability and observability across the risk stack.

You will work closely with C++ Engineers, SREs, Data Engineers, and the risk modelling teams to ensure their containerized services run securely and efficiently in Kubernetes while they phase out legacy environments and move to a unified deployment and monitoring pipeline.

Responsibilities:

Platform Engineering & CI/CD

• Build and maintain robust CI/CD pipelines for complex C++ applications (CMake, Conan, multistage Docker builds, static analysis, sanitizers).

• Optimize build times using caching strategies, distributed compilation, and containerized build agents.

• Automate testing environments, including integration tests involving PostgreSQL, Kafka, and internal services.

Kubernetes & Runtime Operations

• Operate and tune Kubernetes workloads (resource requests/limits, autoscaling, liveness/readiness probes, network policies).

• Build Helm charts and enforce deployment standards (RBAC, secrets management, image scanning).

• Implement zero downtime rolling upgrades, pod disruption budgets, and chaos/resilience testing.

Observability & Reliability

• Improve system visibility through Prometheus, Grafana, ELK/OpenSearch, Open Telemetry tracing.

• Build dashboards and alerts tuned for risk system workloads (latency, throughput, position processing delays).

• Implement structured JSON logging for C++ services.

Data Infrastructure

• Manage high availability PostgreSQL clusters (streaming replication, connection pooling, query optimization).

• Operate and tune Kafka clusters, schema registries, and consumers/producers used by the risk pipeline.

• Support large-scale ingestion of market and account data with strong ordering and replay guarantees.

Risk System Migration & Modernization

• Support the migration from legacy on prem deployments to containerized Kubernetes based services.

• Standardize Docker images for C++ apps, ensuring deterministic builds and reproducible environments.

• Help rearchitect deployment workflows for new real time risk calculation components.

• Collaborate with developers to refactor legacy processes into microservices aligned with event driven architecture.

TECHNICAL PLAYGROUND:

• 5+ years of experience with Kubernetes in production (Helm, Operators, CNI, storage classes, autoscaling)

• Deep understanding of Docker and container image optimization

• Hands-on experience supporting C++ services (CMake, static linking, sanitizers, memory/CPU profiling)

• Operational experience with Kafka (brokers, partitions, retention, consumer offsets, schema evolution)

• Good knowledge of PostgreSQL internals (indexes, VACUUM behavior, EXPLAIN tuning, PITR)

• Solid Linux skills (networking, systemd, kernel parameters, security hardening)

• Experience with GitLab CI, Jenkins, or Azure DevOps pipelines

• Familiarity with infrastructure-as-code tools (Terraform, Ansible, Helmfile, ArgoCD preferred)

NICE TO HAVE:

• Experience with real-time or near-real-time risk or pricing systems

• Knowledge of event streaming patterns (exactly-once semantics, compacted topics, idempotent producers)

• Experience with service meshes, admission controllers, or advanced Kubernetes networking

• Background in performance engineering for high-throughput systems

• Background or understanding of financial services, clearing, and risk management

• Relevant university degree in Computer Science, Engineering, or a related field

SOFT SKILLS:

• Fluent English, with excellent written and verbal communication skills

• Flexible and adaptive working attitude - self-motivated and taking ownership

• Strong interpersonal and assertive communication skills, great team member

• Innovative, big-picture thinking grounded in real-world pragmatism

• Solid experience with IT development in an agile environment, where you get things done through building relationships and convincing people

• Ability to clearly express your thoughts and present work e.g. during sprint review

• Keen to explore ideas and problems through coding in close collaboration with others

• You jump on problems, always ready to take action or escalate issues if it becomes necessary

• An affinity with financial services and risk management

WHAT WE HOPE YOU MIGHT ENJOY:

• Great colleagues, a tech and fun oriented place to work

• Personal and technical development through courses, training, conferences, and certifications under Levi9 Academy umbrella

• Udemy for business

• A delightful book with Bookster

• Parenting sessions if needed

• Team buildings (with the company, your project team, or your department)

• Fun activities with colleagues sharing your passion (Ex: CSR campaigns, Movie Nights, Football, etc.)

• Meal tickets

• 21 annual vacation days + 1 extra day every two years

• Floating holidays

• Vacation Bonus

• Medical subscription

• Hybrid way of working

• Unlimited access to Levi9 gym
