Senior Security Engineer, Cloud Platform
About CelerData
At CelerData, our mission is to empower organizations to fully leverage their data. We achieve this with our cutting-edge, cloud-native, high-performance analytical database, specifically designed for modern lakehouse architectures. We're challenging established solutions like Snowflake, ClickHouse, and Trino by delivering unmatched query performance and a simplified architecture to enterprises globally. Join us as we help our customers convert their data into practical insights and attain outstanding technical achievements.
As a Product Security Engineer at CelerData, you’ll embed with our platform and cloud teams to design and build secure-by-default features for StarRocks and CelerData Cloud. You will drive threat modeling, security assurance, and automation across our control plane, data plane, and BYOC (bring-your-own-cloud) deployments. Your work will span identity, secrets and key management, container / Kubernetes hardening, operating security tooling , and vulnerability management—scaling security through paved roads, tooling, and code .
Key Responsibilities
- Secure design & threat modeling : Partner with PM / engineering to review architectures and data flows (SaaS, on-prem, BYOC). Define security requirements and mitigations for features such as multi-tenant isolation, row / column-level security, auditing, and encryption.
- Security Process : Develop processes, tooling and automation to scale security processes and mitigate risks to the business
- Cloud & Kubernetes hardening : Establish secure baselines for AWS / Azure / GCP; least-privilege IAM; network segmentation and private connectivity (e.g., PrivateLink / Private Endpoint); runtime policies (e.g., Cilium / Calico), admission controls, and secrets handling for K8s.
- Identity & secrets : Advance SSO / MFA for customers and internal systems; standardize OIDC / SAML flows; engineer passwordless and m2m auth; manage KMS / HSM-backed key lifecycles; integrate with Vault for automated rotation.
- Data protection : Ensure encryption in transit / at rest for object stores (S3 / ADLS / GCS) and internal services; define data classification and tokenization / obfuscation patterns where appropriate.
- Vulnerability management & assurance : Run coordinated scanning / fuzzing (including C++ components), triage reports (bug bounty / responsible disclosure), drive fixes to closure with clear SLAs, and commission targeted pentests.
- Detection enablement : Improve security telemetry across control and data planes; contribute product-centric detections / runbooks for abuse, exfiltration, or privilege misuse.
- Incident readiness : Maintain product incident playbooks; participate in investigations affecting CelerData products and customers; lead post-mortems and drive durable remediation.
- Developer enablement : Provide clear guidance, examples, and “paved road” modules (Terraform / K8s manifests, SDK patterns). Deliver practical, lightweight training on secure coding and secrets hygiene.
Qualifications
5+ years in product / application, platform, or cloud security supporting engineering teams shipping distributed systems at scale (or comparable impact).Hands-on with at least one major cloud (AWS / Azure / GCP) and Kubernetes security (RBAC, admission, PSP replacements, runtime policies, image signing).Proficiency in at least one of : Python or Go for automation; plus the ability to read and review C++ and / or Java for security implications.Solid grasp of authN / Z patterns (OIDC / SAML, OAuth2, service-to-service auth), secrets and key management (KMS / HSM, Vault), and TLS mTLS fundamentals.Experience designing controls for multi-tenant SaaS or BYOC architectures (isolation, network egress controls, private connectivity, least-privilege IAM).Clear, pragmatic communicator who can influence design, document decisions, and drive cross-team execution.Preferred Qualifications
Fuzzing experience (e.g., libFuzzer / AFL / OSS-Fuzz) or sanitizers for native code; prior work securing OLAP / DB, storage engines, or high-performance C++ services.IaC security (Terraform + Conftest / OPA checks), cloud org guardrails, SCP / Config / Policy, and drift detection.Familiarity with data security features (RLS / CLS, masking, audit / eventing) in analytics platforms.Contributions to open-source projects (StarRocks / ClickHouse / Trino ecosystems a plus).#J-18808-Ljbffr
