Senior Software Engineer (Full Stack)

Location: Remote

At DiligenceVault , we've built the leading technology platform transforming how due diligence is conducted globally.

Our platform helps organizations streamline and digitize highly manual diligence workflows through automation, data intelligence, and scalable infrastructure. Today, our network includes over 100,000 users across 150+ countries, helping firms improve efficiency, transparency, and decision-making at scale.

We are growing rapidly and looking for exceptional engineers who enjoy solving complex technical problems and building systems that operate at global scale.

Our engineering culture values:

• Strong ownership and accountability
• Deep technical thinking and attention to detail
• Clean, scalable, maintainable engineering
• Continuous iteration and improvement
• Open collaboration and respectful technical debate

We are a team of smart, motivated, and curious builders passionate about creating products users genuinely love.

• Design, build, and maintain scalable backend services using Node.js, Express.js, and TypeScript
• Develop and maintain frontend features in Angular, working closely with designers to deliver clean, performant UIs
• Contribute to API design, ensuring consistency, security, and maintainability
• Design database schemas, write migrations, and optimize query performance across PostgreSQL and SQL Server
• Participate in system design discussions and help define technical direction for new features
• Write well-tested, reviewable code and actively participate in code reviews
• Diagnose and resolve performance bottlenecks across the stack
• Implement security best practices - JWT auth, rate limiting, input validation, prompt shielding
• Own production reliability - PM2 process management, graceful shutdown, health checks, structured logging
• Collaborate cross-functionally with product managers, QA, and other engineers in an agile environment

• 4+ years of professional software engineering experience
• Strong proficiency in Node.js with a solid understanding of the async/event-driven model
• Production experience with Express.js - middleware chains, request lifecycle, error handling
• Fluency in TypeScript - you default to it, not tolerate it
• Hands-on experience building and maintaining Angular applications (v12+)
• Solid understanding of REST API design principles
• Familiarity with relational databases (SQL Server, PostgreSQL, or similar)
• Experience with version control workflows (Git, PR-based development)
• This role is heavily focused on backend architecture. You won't just be writing Node.js endpoints; you will be making critical database decisions. You must have proven experience with:
• Schema Design: Building and normalizing complex relational databases from scratch in PostgreSQL and SQL Server.
• Query Optimization: Moving beyond ORMs to write raw SQL or Stored Procedures, read execution plans and utilize indexes to fix performance bottlenecks.
• Migrations: Writing and safely deploying data and schema migrations in production environments without locking tables.

• Experience building streaming APIs (SSE, chunked transfer encoding)
• Experience with authentication patterns (JWT RS256, OAuth 2.0, SAML)
• Exposure to cloud platforms (Azure, AWS, or GCP)
• Container experience (Docker, Azure Container Instances)
• In-memory caching strategies (TTL-based, firm-scoped)
• Knowledge of observability tooling (logging, tracing, APM)
• Experience in a B2B SaaS or fintech environment
