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.

About the Role
We're looking for a Senior Software Engineer to join our engineering team and help build and scale a modern, data-intensive B2B SaaS platform. You'll work across the full stack - designing robust backend APIs, and contributing to a polished Angular frontend - while collaborating closely with product, design, and fellow engineers.
This is a high-ownership role. You'll be involved in architectural decisions, code reviews, and shaping engineering standards, not just executing tickets.

What You'll Do
- 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

What We're Looking For

Required
- 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.

Nice to Have
- 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
