You should understand the infrastructure your services run on, not treat it as someone else's problem. * Strong SQL and PostgreSQL, including query optimization and schema design against large tables. * Hands-on experience with LLM or ML features, whether in production or through prototypes and experimentation: prompting, evaluation, and understanding how they fail. * Experience using or experimenting with agentic coding tools, and interest in building tooling around them. * Experience mentoring engineers and raising standards on a growing team. * Excellent written and verbal communication - you'll be explaining technical constraints to non-technical stakeholders and to external partners., * Experience with document processing or extraction from unstructured data. * Working knowledge of React and JavaScript. Backend is the focus, but we'd like someone who can pick up frontend work when it unblocks them. * Familiarity with Kubernetes. We have an SRE who owns the cluster - you won't be running it, but you'll be deploying to it and debugging your services in it. * Experience handling sensitive data such as PHI, or working under HIPAA-style requirements. ## Description * Own third-party integrations end to end, and help build the platform that makes new ones fast to stand up. You'll work directly with counterparties' technical teams to define contracts, handle their data formats, and build the abstractions that keep one-off integrations from becoming permanent maintenance debt. * Build and operate ML/LLM systems that extract structure from medical records, lien correspondence, and other unstructured documents - including the evaluation and monitoring that tells you whether they're actually working. * Refactor and decompose monolithic services into systems that scale independently - and operate them once they're live. * Mentor mid-level engineers and set the bar in code review. We're adding engineers quickly this year; the seniors we hire now establish what good looks like for everyone who follows. * Build and maintain backend services and data processing workflows over large datasets, automating what's currently manual. * Operate what you build: troubleshoot production issues and implement security practices appropriate to sensitive legal and medical data. * Work directly with internal stakeholders to translate business needs into technical solutions. ## Related Videos - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [The Laravel Core - Demystify The Beast](https://www.wearedevelopers.com/videos/98-the-laravel-core-demystify-the-beast) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [API Platform: From Rest & GraphQL APIs to state-of-the-art standards in seconds](https://www.wearedevelopers.com/videos/1968-api-platform-from-rest-graphql-apis-to-state-of-the-art-standards-in-seconds) ## Related Articles - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe)
