Job description

We're looking for experienced engineers who've built real products at scale and apply that same rigor to platform engineering. You'll engineer new platforms as products, not just operate existing infrastructure. You understand user experience, reliability, and technical debt from shipping production systems. You'll design platforms that are extensible, observable, and maintainable, enabling internal teams to build on top of them while handling the complexity underneath.

• Programming languages: GoLang, Java11, Kotlin, Rust, Python
• Storage & Persistence: S3, NFS
• Container and Orchestration: Kubernetes/Containers (Docker)/Rancher RKE
• Cloud providers: AWS, GCP, Azure, Private Data Centers
• Observability/Telemetry: OpenTelemetry, Prometheus, Grafana
• Deployment: Jenkins, ArgoCD

DEIB improves our workforce, enhances trust with our partners and customers, and drives business success. Build your career in a place where diversity, equity, inclusion and belonging aren't just words on paper - this is what drives our innovation, it's how we connect, and it contributes to what makes us a market leader.

We hire you for who you are, and we want you to bring your authentic self to work every day!

• Extend offers to candidates without an extensive interview process with a member of our recruitment team and a hiring manager via video or in person.
• Send job offers via email. All offers are first extended verbally by a member of our internal recruitment team whenever possible and then followed up via written communication.

Are you a creative problem solver who can both give and receive feedback? Do you lead with inclusion, collaboration, and openness? Do you have strong experience with high-scale B2B and B2C platforms?

As a Senior Platform Engineer, you'll be crafting and helping build the next generation of the Anaplan Platform. You're comfortable with both full-stack systems design for the hybrid cloud as well as hands‑on distributed systems programming with extensive knowledge of Java, JVM, Rust, Linux internals and container orchestration.

You don't just write Helm charts or YAML manifests; you extend the Kubernetes API.

• Custom Operators: Proven ability to write Kubernetes Operators (using Kubebuilder or Operator SDK) to manage complex, stateful application lifecycles.
• Control Plane Logic: Deep understanding of reconciliation loops, custom resource definitions (CRDs), and how to automate operational knowledge into code

Scalable Microservices & Distributed Systems You build for high concurrency, low latency, and eventual consistency.

• High-Scale SaaS: 10+ years of experience building and operating production-grade SaaS products. You have first‑hand experience with the "death by a thousand cuts" that comes with scaling to millions of requests.
• Systems Programming: Advanced proficiency in Go, Rust, or JVM‑based languages, with a focus on writing memory‑efficient and thread‑safe code.
• Storage Internals: We need more than S3 API knowledge. You should understand the performance characteristics, limitations, and cost‑drivers of S3, NFS, and enterprise storage like NetApp OnTap or AWS FSx.
• Data Locality: Experience managing data persistence across hybrid environments (Public Cloud vs. Private DC).

Operational Maturity (The "SRE" DNA) You believe that "if it isn't monitored, it doesn't exist."

• Instrumentation: Expert-level experience with OpenTelemetry. You don't just look at metrics; you design the telemetry that allows for deep‑diving distributed tracing and root‑cause analysis.
• Observability Infrastructure: Hands‑on experience scaling Prometheus and Grafana to handle high‑cardinality data.

• BS degree in Computer Science, related technical field, or equivalent practical experience as a professional Platform Engineer.
• Substantial experience in Java, RUST programming experience
• Proven experience in building and operating a SaaS product at scale.
• Proven cloud experience using observability and operating workloads in Kubernetes.
• Experience with cloud storage S3, NFS, NetApp OnTap, AWS FSX
• Distributed Systems and programming techniques.
• Monitoring and metrics infrastructure (OTEL, Prometheus, Grafana).
• Cloud (AWS / GCP/ Azure / Private DC).
• Bonus: Experience with AI/ML, Natural Language
