ToucanTix·REMOTE (EU/US timezones preferred) Your code will run the gates at zoos and theme parks across Germany and the USA. When families scan tickets, when capacity limits kick in based on visitors and available resources (staff, equipment, facilities), when dynamic pricing adjusts for weather - that's our Rails app making real-time decisions for thousands of visitors daily. We're 5 engineers at ToucanTix (sister company Combase has 80+). You'd have serious ownership and architectural influence from day one. Technical challenges that actually matter: Multi-tenant architecture supporting 100+ venues with wildly different business logic. Offline-first POS that syncs flawlessly. Complex pricing rules (weather + season + capacity + customer type) that need to stay performant. Hardware integrations with access control and payment systems. Stack: Rails 7+ API with GraphQL (graphql-ruby), PostgreSQL doing serious heavy lifting with multi-tenant architecture, Redis for speed-critical stuff, SvelteKit frontend (if you're full-stack curious), Google Cloud infrastructure (Cloudtasker, Cloud Storage), RSpec/Capybara keeping everything bulletproof You: 5+ years Rails. Strong at PostgreSQL optimization. Have architected systems for performance and scale. Comfortable owning technical decisions. Us: Real ownership. No layers of management. Async-first remote culture. Profitable company, not burning VC cash. Your work has physical impact - people literally can't enter the attraction if your code breaks. Full details: https://www.toucantix.com/careers/senior-ruby-on-rails-devel... Apply: [email protected] - Send CV + one technical challenge you're proud of solving. Put in subject line.

Erdos Miller·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 [email protected] with your background and what excites you about wrangling data.
