Innolitics | Medical Device Engineers + Physician-Scientist (MD/PhD) | REMOTE (US) | Full-Time
Innolitics builds AI/ML software for medical devices — the kind that detects ear infections, tracks metastatic cancer, and plans radiation therapy. 60+ FDA clearances. We need engineers who want their work to matter. We're a remote-only firm (since 2012) that does engineering, regulatory, and cybersecurity under one roof. Our team includes MDs, PhDs, and software engineers. Clients range from Series A startups to large device companies. We're hiring for three roles:
1. Physician-Scientist (MD/PhD) — Biostatistics & AI Software Development MD + PhD in biostatistics, bioinformatics, epidemiology, or a related quantitative field. You'll design biostatistical plans for AI validation studies (MRMC, standalone, prospective), build production-grade statistical software and data pipelines, write FDA-facing statistical sections, and analyze large clinical imaging datasets. Fluent in Python and/or R. This is not a pure research role — you'll ship code that gets FDA-cleared and deployed in clinics.
2. Senior Web/Mobile Medical Device Engineer 5+ years SWE experience. 3+ years each in web and mobile. Fluent in TypeScript and Python. You'll build medical device software and produce FDA-facing technical documentation. Cross-functional role bridging engineering and regulatory teams.
3. Medical Device Software Engineer 3+ years SWE experience. Fluent in Python, C++, or TypeScript. Heavier emphasis on software development initially; you'll grow into regulatory documentation work over time. All roles involve writing production code for medical devices, authoring documentation for FDA submissions, and working directly with clients. No prior medical device experience required — we'll teach you. Why engineers stay here:
Agentic AI tools (Claude Code, etc.) are part of our workflow. We treat them as a impact multiplier, not a threat. ~1 hour of meetings/week for ICs. Flexible hours. 2 hours every Wednesday dedicated to learning ("10x Time"). Healthcare-only revenue. No debt. Never had a layoff. We pay $300 for take-home exercises because your time has value.
Stack: Python, TypeScript, C++, R, Django, React, TensorFlow, PyTorch, scikit-learn, Qt, Terraform.

Strobe | Senior Infrastructure & Data Integration Engineer | Brooklyn, NYC | ONSITE | Full-time
Strobe is building the world's largest power plant — not a single site, but a distributed fleet of buildings, batteries, EVs, and generators buying and selling power in real time across wholesale energy markets.
We need a software engineer to take ownership of our data integration and cloud infrastructure layer — the connective tissue between utilities, grid operators, OEM hardware, weather services, and our energy optimization engine.
What you'd own:
- Wholesale market integrations (NYISO, CAISO, ERCOT) — real-time pricing, capacity markets, demand response signals - OEM hardware integrations — API and data bridges to building equipment manufacturers for monitoring, control, and telemetry - Green Button Connect pipelines — ingesting interval consumption, billing, and meter data from utilities (ConEd, PG&E, SCE, etc.) via OAuth2 + ESPI - Weather and solar forecast data pipelines - Utility bill reproduction engine — modeling site economics before and after Strobe to forecast financial impact across dozens of rate structures. This simulation infrastructure is core to how we sell and deliver value. - Event-driven AWS infrastructure (Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, TimeStream, Amplify, CloudWatch) - Terraform IaC — real module design, remote state, multi-workspace patterns - Observability and alerting on systems where downtime means missed market events and real dollars
Strong fit if you have:
- Deep AWS experience (IAM, Lambda, API Gateway, AppSync, EventBridge, TimeStream or similar TSDB) - Production Terraform (modules, remote state, multi-workspace patterns) - Extensive Python (pydantic for models, click for CLIs, boto3 for AWS, async pipelines) - Experience integrating messy third-party APIs at scale (utilities, government, energy, OEMs) - Comfort with on-call for systems that control physical hardware and move real money
Stack: monorepo (heavily AI-agent-optimized) / Python / TypeScript / Rust / Terraform / AWS.
Small team (<10), high ownership, no layers. 5 days/week onsite at Newlab, Brooklyn Navy Yard.
