The Vera C. Rubin Observatory in Chile is a new world-class astronomy facility designed to create a 10-year time-lapse map of the southern sky. Featuring the world’s largest digital camera it emits 20GB of raw pixels per minute, and we are developing the Prompt Processing System that will distribute an alert on every astrophysical object that has moved, changed or appeared in real-time. (https://rubinobservatory.org/news/first-alerts)
This appointment is based at SLAC, a DOE-funded national laboratory hosting the data facility and many of the 80 scientists and engineers of the world-wide Rubin Data Management team. (https://www6.slac.stanford.edu/)
Keep Rubin's Alert Stream flowing. We are hiring an SRE to own the reliability of our Prompt Processing Framework, a Kubernetes-based, event-driven system using KEDA, Redis Streams, Kafka, and Postgres to scale near-real-time processing. You’ll write software to improve resilience, operate and evolve core infrastructure services, and build the monitoring, alerting, and on-call practices that keep the system robust and reliable during nightly observing operations.
Stack: Python, Kubernetes, Helm, ArgoCD, Kafka, Redis, KEDA, InfluxDB, PostgreSQL, Cassandra.

Senior/Staff Python Engineers for our patient experience and core teams!
Ro is building an end-to-end healthcare platform (telehealth + labs + pharmacy) used by 2M+ patients. We’re hiring senior backend engineers who want e2e ownership: you’ll drive projects from problem framing → architecture → shipping incremental improvements → measurement and iteration, partnering closely with product/design/clinical.
What you’ll own: - Lead critical initiatives end-to-end with team members - Make pragmatic architecture decisions and raise the bar on quality (observability, performance, correctness) - Coach/lead through influence: reviews, design docs, unblocking, setting standards - Ship in small slices with measurable outcomes (not “big bang” rewrites)
Stack: Python, FastAPI, Postgres, AWS, Redis, Kafka/queues, Docker/K8s, observability tooling
Open roles (apply here): https://ro.co/careers/#open-roles
Other roles we’re also hiring for: SRE, iOS, and a few leadership roles (see job board).
Adobe is building a Real-Time Customer Data Platform (CDP) that operates at a scale most companies never see. We aren't just building another "enterprise app"; we are managing trillions of events and solving complex state problems in real-time.
If you find "distributed systems" a lifestyle rather than a buzzword, we want to talk. We are currently tackling challenges in high-throughput streaming, identity resolution at scale, and sub-millisecond data retrieval.
The Stack:
Core: Java, Scala, Spring Boot
Compute/Stream: Spark, Flink, K8s
Storage/Messaging: Kafka, FoundationDB, Aerospike, Cosmos DB, Delta Lake
Infrastructure: Multi-cloud (Azure/AWS), Docker, Vector DBs
What we’re looking for:
The "8+ Years" Profile: You’ve spent a decade breaking and fixing large-scale distributed systems.
Concurrency & Performance: You don’t just write code; you tune it. You understand the JVM, memory models, and how to squeeze performance out of every thread.
Architecture: Experience with Flink/Kafka/Spark isn't just about using the API—it's about knowing how they fail and how to keep them running under massive load.
The Logistics:
Locations: San Jose, New York, or San Francisco (Hybrid/Onsite).
Comp: $177,900 – $257,550 base + Equity + Adobe’s notoriously good benefits.
How to Apply: Email me directly at skatkar@adobe.com with "HN: [Your Name]" in the subject line.
