About our Client

Our client is building an enterprise-ready AI coworker for procurement, legal, and sales teams. Its platform connects with the systems companies already use—including ERPs, contract platforms, email, and collaboration tools—to review contracts, surface risks, track obligations, and deliver grounded answers with citations to the underlying source data.

Rather than requiring customers to replace their existing workflows, Vallor integrates directly with their technology stack and helps teams automate contract review, negotiation, renewals, compliance, and value recovery.

Our client is an early-stage company with an 11-person team and a highly AI-native engineering culture. As the company expands its enterprise customer base, it is looking for a senior engineer who can combine excellent product engineering with ownership, customer empathy, and strong technical judgment.

About the Role

We’re looking for a Senior or Staff Software Engineer who is highly proficient in TypeScript, strong on the backend, and comfortable contributing across the full stack.

You’ll join a small engineering team and take meaningful ownership of architecture, implementation, and delivery. Your initial work will support an important enterprise customer, requiring you to collaborate directly with stakeholders, translate their needs into product capabilities, and deliver high-quality solutions independently.

This is an excellent opportunity for an engineer who enjoys early-stage environments, modern serverless architecture, customer-facing problem-solving, and AI-native software development.

What You’ll Do

• Design, build, and ship production features across Vallor’s TypeScript stack

• Own backend services, APIs, integrations, data flows, and serverless infrastructure

• Contribute to the frontend when needed using Next.js and TypeScript

• Work directly with enterprise customers to understand their workflows and technical requirements

• Translate customer needs into well-scoped, maintainable product features

• Communicate tradeoffs, clarify requirements, and push back constructively when needed

• Build integrations across enterprise systems, contract platforms, communication tools, and third-party APIs

• Design and maintain serverless, event-driven systems on AWS

• Contribute to infrastructure-as-code workflows using SST and related tooling

• Use AI coding agents extensively to accelerate development and parallelize work

• Review, test, debug, and improve AI-generated code rather than accepting raw output

• Maintain a high standard for code quality, security, reliability, and maintainability

• Help shape engineering practices and technical direction as the team grows

• Identify opportunities beyond the initial customer requirements and turn them into valuable product improvements

What We’re Looking For

• Senior or Staff-level software engineering experience

• Deep professional experience with TypeScript

• Strong backend engineering skills using Node.js, Bun, or similar runtimes

• Ability to contribute across the full stack, including modern React or Next.js applications

• Experience building and operating production systems on AWS

• Strong understanding of serverless and event-driven architecture

• Experience designing APIs, integrations, and distributed backend workflows

• Experience with PostgreSQL or similar relational databases

• Familiarity with infrastructure as code

• Strong product judgment and ability to turn ambiguous needs into shipped solutions

• Excellent written and verbal English communication

• Ability to work directly with customers and non-technical stakeholders

• Strong organization, attention to detail, and project ownership

• Experience using advanced AI coding tools or agents as a core part of daily development

• Ability to critically review and take ownership of AI-generated code

Strong Advantages

• Previous experience as a founding engineer or early-stage startup engineer

• Experience in a forward-deployed, solutions engineering, implementation, or technical consulting role
