About the Role

This is a high-impact individual contributor role on our platform team, building large-scale data pipelines and distributed systems that power Sidecar Health's core product. You'll take full ownership of complex, ambiguous problems from architecture through production — designing, shipping, and running the systems you build. If you're a strong senior engineer who thrives on end-to-end ownership and wants your work to matter in healthcare, this is the role for you.

→Design and own high-throughput, distributed data pipelines and platform infrastructure from concept through production
→Decompose large, ambiguous initiatives into structured, executable plans that the team can move on in parallel
→Write production-grade Python — strongly typed, well-structured, and built to last — not scripts or notebooks
→Optimize SQL at scale: query tuning, data modeling, and understanding execution plans
→Architect across boundaries — defining contracts between frontend, backend services, and infrastructure
→Be a technical resource and mentor for junior engineers, and partner directly with leadership on roadmap and technical decisions
→Instrument systems for observability — knowing what to monitor, not just how to read a dashboard

5+ years of professional software engineering experience with full ownership of production systems
Strong proficiency in Python (mypy, Pydantic, proper abstractions) and SQL at scale
Deep experience building and operating distributed data pipelines and event-driven architectures
Hands-on AWS experience: Lambda, SQS, IAM, CloudWatch, and cost-aware design
Docker as a first-class practice
Habitual, fluent use of AI tools (Claude, Cursor, etc.) as part of your daily workflow
Observability experience with Datadog or equivalent
Familiarity with FastAPI, Django, SQLAlchemy, Celery, or Infrastructure-as-Code (Terraform, CDK) is a strong plus
Bachelor's or Master's degree in Computer Science, Information Systems, or a related field

The Reality

This is a startup. We move fast. We prioritize impact over polish. We expect:

Bias for action — ship, learn, iterate
Ownership — you design it, build it, run it
Pragmatism — solve real problems, not theoretical ones
Resilience — ambiguity comes with the territory

Healthcare is complex and broken. The work matters.

What You'll Get

Competitive salary, bonus opportunity, and equity package
Comprehensive Medical, Dental, and Vision benefits
A 401k retirement plan
Paid vacation and company holidays
Opportunity to make an impact at a rapidly growing mission-driven company transforming healthcare in the U.S.
