The Role:
We are looking for a deeply hands-on Staff Distributed Systems Engineer to join the team building IonQ's Network and Security Platform. You will own the backend services - ingestion pipelines, telemetry processing, device management - that give operators real-time visibility into their networks and the intelligence to make them quantum-safe. This is infrastructure that matters: the systems you build will underpin IonQ's mission to secure the world's networks against quantum threats.
In this role, you will own backend services end-to-end - from high-throughput ingestion pipelines collecting telemetry from large device fleets, to time-series storage, real-time processing engines, and the APIs that surface platform data to the rest of the organization. You are a deeply hands-on engineer who writes production-quality Go and/or Rust daily, takes pride in operational ownership, and brings strong distributed systems fundamentals to every problem you tackle.
You will work closely with the Principal Architect to translate platform architecture decisions into reliable, well-tested, production-grade implementations. The ideal candidate has direct experience building data-intensive backend systems at scale - and is energized by the challenge of making complex infrastructure simple, observable, and dependable.
Responsibilities:
Backend Services & Production Code

• Design and ship production backend services in Go and/or Rust, measured by code quality, test coverage, and on-time delivery of service milestones.
• Build and maintain high-throughput telemetry ingestion pipelines using gNMI, NETCONF, and SNMP, ensuring reliable data collection across large device fleets.
• Develop RESTful and gRPC APIs that expose platform data to internal consumers and external integrations, evaluated by uptime, latency SLAs, and adoption by downstream teams.

Data Engineering & Storage

• Implement and evolve the time-series storage layer (InfluxDB, TimescaleDB, or equivalent), optimizing for query performance, retention policies, and data fidelity under production load.
• Build event streaming pipelines using Kafka or Kinesis with at-least-once or exactly-once semantics, validated through integration tests and production monitoring.
• Design data partitioning and archival strategies that sustain target ingest volumes while meeting defined latency and durability SLAs.

Platform Reliability & Operations

• Own service reliability end-to-end - participate in on-call rotation, lead incident response, and drive systemic improvements tracked via post-mortems and reduction in repeat incidents.
• Instrument all services with structured logging, distributed tracing, and metrics (OpenTelemetry, Prometheus) so that production issues can be diagnosed and resolved within defined SLOs.

Cloud-Native Infrastructure

• Package and deploy services as containerized workloads on Kubernetes, maintaining infrastructure-as-code (Terraform) across AWS, GCP, and Azure environments.
• Contribute to multi-cloud deployment patterns that meet platform availability targets and data residency requirements.

Collaboration & Engineering Quality

• Partner with the Principal Architect to translate platform architecture decisions into tested, production-grade implementations with clear engineering specifications.
• Lead code reviews and serve as the primary technical authority for the team's engineering standards; mentor junior and senior engineers through pairing and guidance, establishing patterns and practices that raise the bar across teams.

Requirements:

• 8+ years of backend software engineering experience, with a strong record of shipping production services at scale.
• Proven, hands-on proficiency in Go and/or Rust - you write these languages regularly and can demonstrate production systems you have built with them.
• Solid experience building and operating distributed data systems: event streaming (Kafka, Kinesis, or equivalent), time-series databases, and high-throughput ingestion pipelines.
• Strong fundamentals in distributed systems: consistency models, failure modes, backpressure, idempotency, and exactly-once vs. at-least-once processing tradeoffs.
• Experience with cloud-native deployment: containerization (Docker), Kubernetes orchestration, and operating services across at least one major cloud provider (AWS, GCP, or Azure).
• Familiarity with observability tooling - structured logging, metrics (Prometheus/Grafana or equivalent), and distributed tracing (OpenTelemetry or equivalent).
• Comfortable writing SQL and working with both relational and time-series data models; experience with schema design and query optimization.
• Strong engineering practices: test-driven or test-informed development, code review, CI/CD, and operational ownership including on-call.
• Demonstrated ability to drive technical decisions and influence engineering direction across multiple teams, with a track record of cross-functional technical leadership.

Preferred Qualifications:

• Experience with network telemetry protocols (gNMI, NETCONF, SNMP) or prior work at a network equipment vendor or network management platform company (e.g., Juniper, Cisco, Nokia).
• Hands-on experience with graph databases or graph data models for network topology (e.g., Neo4j, Amazon Neptune, or custom adjacency representations).
• Familiarity with YANG data modeling or prior experience working with device configuration schemas in network management contexts.
• Experience building multi-tenant SaaS backend services with strong data isolation and per-tenant resource management.
• Contributions to open-source infrastructure, observability, or networking projects; or published technical writing on distributed systems topics.
• Experience working in or adjacent to regulated, security-conscious environments (FedRAMP, NIST, or equivalent).

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying "U.S. Person" (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
