About The Role

As a Senior Backend Engineer, you’ll be designing and architecting scalable solutions, creating robust APIs, and building new microservices from the ground up—while also improving and optimizing our existing systems. This isn’t just another engineering role. We’re solving real, painful inefficiencies in the insurance space – problems so frustrating that prospects have nearly teared up during sales calls, realizing how much time and effort we could save them. What we’re building isn’t just an upgrade – it’s a fundamental shift in how agencies operate.

What You’ll Do:

• Architect and develop scalable TypeScript microservices powering XILO’s platform.
• You’ll have the opportunity to work where your strengths shine and contribute to:
  ○ AI Agents – Automating complex decision-making and workflows
  ○ OCR & Document Processing – Extracting, structuring, and analyzing key insights from insurance documents
  ○ Intelligent Data Mapping – Aggregating and linking all relevant data into a centralized, dynamic user profile
  ○ Advanced Insurance Operations & CRM – The AI-powered backbone of agencies, seamlessly tracking, managing, and integrating customer data across tools and workflows while replacing outdated, manual processes
  ○ Forms Builder & Smart Data Entry – A Typeform-like system built for insurance, enabling error-proof, collaborative submissions – fill once, apply everywhere
• Optimize system performance, reliability, and scalability.
• Collaborate with cross-functional teams (product, frontend, data science) to deliver seamless integrations.
• Mentor and guide junior engineers, fostering a collaborative and growth-oriented team culture.
• Implement best practices for API security, data privacy, and maintainability.
   

What we’re looking for

• 7+ years of backend development experience, with a strong foundation in TypeScript and JavaScript.
• Proven expertise in designing and developing software product features, with a focus on scalability, performance, and maintainability.
• Proven expertise in REST API design – including authentication, performance optimization, and security best practices.
• Experience with XML and SOAP-based integrations, commonly used in the insurance industry.
• Strong hands-on experience with Nest.js, leveraging its modular architecture for scalable backend services.
• Familiarity with NX monorepos for structuring and maintaining large-scale applications.
• Cloud deployment experience on Heroku and AWS, including CI/CD pipelines and infrastructure management.
• Deep understanding of database management, ORM usage (e.g., TypeORM, Prisma, Sequelize), and zero-downtime migration strategies.
• Experience designing and implementing microservices architectures, including inter-service communication, data consistency, and service decoupling.
• Bonus: Full-stack experience with modern frontend frameworks like Angular.

What we offer

• Collaborative and innovative work environment
• Flex PTO for any reason, including sick days (no specified limits), flexible work schedule.
• Personal laptop.
• Health and wellness package.
• Budget for English lessons.
