Company mission
To build and deploy useful, fault tolerant quantum computers.
Role
Who you are
- Bachelor’s Degree or higher in Computer Science, Engineering or other related technical field
- 10+ years in software engineering, focusing on high performance data pipelines
- Proficiency in Python and at least one compiled language (Rust, Go, C++)
- Experience with streaming/messaging platforms (Kafka, Pulsar, Flink, RabbitMQ)
- Strong background in real-time data pipelines and observability stacks (OpenTelemetry, Prometheus, Grafana, ELK)
- Deep knowledge of high-performance databases (time-series, document, object-store)
- Familiarity with API design (REST, gRPC, Protobuf, Avro)
- Experience with containerized workflows (Docker, Kubernetes)
- Able to work effectively across a number of different teams/functionalities
- Excellent communication skills
What the job involves
- PsiQuantum’s Electronic OS Platform team is seeking a Staff Software Engineer to design and build the data acquisition and observability stack
- This role focuses on developing scalable, high-performance data pipelines that enable real-time ingestion, logging, metrics collection, and tracing across distributed systems
- Architect document and implement a real-time data acquisition and observability framework, supporting logs, metrics, and traces
- Develop high-throughput data pipelines for ingestion, transformation, and storage
- Build API services and integrations for system monitoring and device communication
- Optimize pipeline performance for low-latency, high-bandwidth environments
- Collaborate with calibration and infrastructure engineers on deployment and data engineers on schema and reporting needs
- Maintain monitoring, alerting, and visualization tools for system observability
- Ensure security, compliance, and scalability across cloud and on-prem environments
- Gather functional requirements from external stakeholders, refining them into technical requirements considering performance, scalability, and usability
- Troubleshoot complex problems and incidents, working with cross-functional teams and end-users to identify root causes
Our take
Quantum computing will change the world more than any other imminent technological development, and PsiQuantum sits at the forefront of the charge to build the first quantum computer that will actually work.
The company is unique for the scale of their ambitions. Rather than focusing on what they term “intermediate milestones” like building smaller proof of concept systems, PsiQuantum builds the first large-scale, error-corrected computer, using photonics to deliver over 1,000,000 qubits (current quantum machines have yet to cross the 1,000 qubit mark).
There are plenty of companies building quantum computers, including the likes of IBM and Google, but these prototypical machines lack the size to correct errors, making them exponentially less useful than what PsiQuantum aims for. While other companies operate in the same sphere, PsiQuantum is unequivocally a leader in its field, founded by world-class academics and recently securing $1B in funding, making it the largest funding round for a quantum computing startup.
