Company Description RealDayEye is an AI-focused company that helps businesses improve efficiency, decision-making, and customer experience by embedding artificial intelligence into everyday operations in a practical and measurable way. The company builds intelligent, cloud-based platforms that automate complex, document-intensive workflows, with a strong focus on regulatory compliance and income verification in highly regulated sectors such as U.S. real estate. Its platform combines document AI (OCR, parsing, structured data extraction) with a configurable rules engine to process, validate, and audit large volumes of documentation while reducing manual work and human error. Delivered as a multi-tenant SaaS solution, the system supports end-to-end workflows, including document ingestion, AI-driven data extraction, rule evaluation, human-in-the-loop validation, and audit-ready analytics. Early prototypes have been validated by major institutional real estate firms, demonstrating strong market demand for RealDayEye’s automation and compliance solutions. Role Description This is a full-time hybrid role based in Badalona, with flexibility for partial work from home. The Full Stack Node.js/PostgreSQL Engineer with AI for Financial Institutions will design, develop, and maintain scalable backend and frontend services that power RealDayEye’s AI-driven platforms for financial institutions and regulated environments. Day-to-day responsibilities include building and optimizing RESTful and/or GraphQL APIs in Node.js, designing robust PostgreSQL schemas and queries, and integrating AI components such as document processing and rules engines into production workflows. The engineer will collaborate with product, AI, and compliance teams to translate complex regulatory requirements into reliable technical solutions, improve system performance, security, and observability, and ensure high availability in a multi-tenant SaaS architecture. The role also involves writing clean, testable code, reviewing peer contributions, participating in architecture discussions, and supporting deployment and monitoring in cloud environments. Qualifications Strong backend engineering skills with Node.js, including experience building APIs, handling authentication/authorization, and working with asynchronous patterns. Proficiency with relational databases, especially PostgreSQL, including schema design, query optimization, indexing, and data integrity best practices. Experience with frontend development using modern JavaScript frameworks (e.g., React, Vue, or similar) and building responsive, user-friendly interfaces. Hands-on experience integrating AI/ML services or document AI workflows (e.g., OCR, data extraction, validation pipelines) into production systems. Knowledge of cloud platforms (such as AWS, Azure, or GCP), containerization (Docker), and CI/CD pipelines for deploying and maintaining SaaS applications. Familiarity with security, data privacy, and compliance considerations in financial or highly regulated domains, including auditability and traceability. Comfort working in hybrid
Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
