Our client develops a comprehensive US real estate platform that streamlines the entire real estate journey through property search, personalized client engagement, transaction management, digital contract signing, and post-sale concierge services.
We are looking for a self-driven and proactive Senior Software Engineer who enjoys working in a startup environment with lightweight processes, dynamic product development, and a strong sense of ownership — including pragmatic problem-solving, finding efficient implementation approaches, participating in trade-off discussions, and closely collaborating with Product Owners. This role focuses heavily on system hardening, performance optimization, and error reduction as the platform scales.
Type of engagement: outstaffing team extension for ongoing collaboration (with daily overlap until 8:00 PM EEST)
What’s interesting about this project:
Work on a real estate platform with multiple business domains, including property search, transaction flows, digital signing, and post-sale services
Work as part of a distributed multinational team with direct collaboration across engineering and product functions
Startup-style environment with lightweight processes, fast delivery cycles, and pragmatic engineering trade-offs
High level of ownership and involvement in solution discussions, implementation decisions, and feature shaping
Complex technical challenges, including e-signature processing, asynchronous workflows, and notification systems
Close collaboration with Product Owners and direct communication with client stakeholders
Opportunity to work across different parts of the platform as the product evolves
Stack: TypeScript, Node.js, Express, PostgreSQL, MongoDB, RabbitMQ, Redis
Scope of tasks and ownership:
Identify bottlenecks, eliminate system errors, and profile applications to optimize memory
Harden the backend architecture by introducing fault-tolerance patterns, advanced error handling, and data validation
Optimize database queries, indexing strategies, and caching layers to minimize API latency and maximize performance
Improve system visibility and error reduction by enhancing structured logging, metrics, and monitoring
Design and implement clean internal APIs for transaction management, e-signature, and notification systems
Refactor large-scale monolithic code while maintaining backward compatibility during transition
Collaborate with a cross-functional team, including software engineers, QA, DevOps and designers
Work closely with the PO (client) to ensure alignment with business objectives
Participate in sprint planning and maintain strong asynchronous communication practices
What You’ll Need:
5+ years of full-stack software engineering experience with a strong backend focus
Strong proficiency in TypeScript, Node.js, and RESTful API development
Solid experience with PostgreSQL and MongoDB
Experience with system hardening, reducing error rates in production, and implementing resilient backend patterns
Hands-on experience with message queuing systems (RabbitMQ) and caching solutions (Redis)
Experience with async workflow processing and event-driven architecture patterns
Familiarity with application performance monitoring (APM) and backend debugging tools
Active use of AI-assisted development tools
Legacy system modernization experience strongly preferred
Strong communication skills for client collaboration and remote team coordination
Comfortable working in agile, cross-functional environments with direct client interaction
Upper-Intermediate English level minimum
Nice-to-have:
E-signature technologies
Notification system design
Real estate domain knowledge
