Erdos Miller | Data Wrangler (Part-time → Full-time growth) | Remote (US preferred, flexible otherwise)

We build Measurement While Drilling (MWD) equipment — and we love it. That passion helped us capture the majority of the North American oil & gas market, and now it’s fueling our geothermal innovation, building underground navigation systems for the next generation of clean energy.

We’re now looking for a Data Wrangler to help us make smarter, faster decisions with our data. This role blends data engineering and data science: wrangling quirky file formats, structuring messy datasets, and turning it all into live tools that guide company strategy. Starts part-time with the opportunity to grow into a full-time, career-defining role. What you’ll do

Partner with the CEO + stakeholders to translate business needs into pipelines, dashboards, and tools. Build ETL pipelines, write parsers for proprietary formats, and maintain relational databases (PostgreSQL, MySQL). Create interactive dashboards/apps with Dash, Streamlit, or similar (we avoid Tableau/Excel hell). Deliver insights via live web apps where data isn’t static — it’s explorable. Tech we use Python, SQL (PostgreSQL/MySQL), S3, modal.com. Bonus: React/web dev experience to shape customer-facing real-time tools. Why you’ll like it here You’ll own projects end-to-end, avoid over-engineering (no Kubernetes, no Airflow — just the right tools), and directly influence decisions. As our company and data needs grow, so does your role. If this sounds fun, email ken@erdosmiller.com with your background and what excites you about wrangling data.

Tandem Health | Senior/Staff Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)

Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.
