You'll work hands-on with Node.js, TypeScript, PostgreSQL, MongoDB, AWS, and Docker, partnering closely with product, frontend, and DevOps teams to ship high-quality, cloud-native features at startup speed. A key part of this role is production ownership - partnering with our support team to troubleshoot at-scale production issues, driving root cause to resolution, and hardening the platform so problems stay fixed. You'll also coordinate closely with our US architects and India-based engineering team for new features. This is a high-ownership role for an engineer who loves solving hard distributed-systems and data problems in a domain where reliability, performance, and security truly matter. You'll take end-to-end ownership of major workstreams alongside our most senior architects - freeing them to focus on next-generation platform initiatives. Join us and make a meaningful, sustainable impact alongside some of the industry's brightest minds., * Design & Build: Architect, develop, and maintain scalable RESTful APIs and backend services using Node.js and TypeScript, powering mission-critical loan origination workflows. * Data Engineering: Design efficient database schemas and optimize queries and migrations across PostgreSQL and MongoDB; implement caching strategies (e.g., Redis) for high-throughput workloads. * Cloud & Containers: Build, test, and deploy containerized applications with Docker; deploy and operate services on AWS (EC2, Lambda, RDS, S3, SQS). * DevOps Collaboration: Partner with DevOps to strengthen CI/CD pipelines, infrastructure-as-code, and observability (logging, metrics, tracing, alerting). * Reliability & Security: Champion system reliability, performance, and secure coding best practices - our platform handles sensitive borrower data, and we operate in a SOC 2 Type II environment where security is a first-class engineering concern. * Production Ownership: Partner with our Support team as an engineering point of contact for escalated production issues at scale - triage, root-cause, and resolve end-to-end, then land the permanent fix, alerting, and runbooks so issues don't recur. Drive performance optimization across the backend and data layers. * Global Collaboration: Coordinate daily with our India-based engineering team - handoffs, code reviews, and design alignment - keeping core hours of 7:00 AM - 4:00 PM PT to maximize morning overlap. * Technical Leadership: Lead technical design sessions and code reviews, mentor mid-level engineers, and contribute to product planning and architectural roadmaps. ## Related Videos - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [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) - [Accelerating Authentication Architecture: Taking Passwordless to the Next Level](https://www.wearedevelopers.com/videos/733-accelerating-authentication-architecture-taking-passwordless-to-the-next-level) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers)
