IonQ | Senior Research Software Engineer | Boston, MA (ONSITE - Hybrid) | Full-time

We are looking for a Senior Research Software Engineer for our Global R&D team at IonQ. You'd build the software our quantum scientists rely on for lab orchestration, experiment data, and hardware control. If you've written software that talks to real instruments and wrangles real, messy, physical-world data, this might be for you.

Looking for: 5+ years of experience, strong Python skills, ownership of the full software development lifecycle, observability, and CI/CD. Hardware or lab-data experience is the bar.

No physics background is required!

Octozi | Founding Engineer | Brooklyn, NY | ONSITE | Full-time | https://octozi.com

Clinical trials cost about $1B each and roughly $1M for every day they run late. They are still run on manual data review: people checking data by hand across spreadsheets and PDFs, hoping nothing was missed.

We automate it. Continuous data cleaning, data that stays analysis-ready, and signals across the whole study so sponsors can make decisions on data they trust.

What that means in practice: - Reconciling data from many systems that describe the same patient differently - A rules engine expressive enough that new studies get configured, not coded - Findings a clinician will act on, which means correct and self-explaining - Real product surface: this is what people stare at all day

In production with pharma sponsors. Small team, second engineering hire, no legacy to defend.

Stack: Django/Python, React, AWS. SOC 2 Type II.

Comp: $170-220K + equity.
