Senior/Staff TypeScript Engineer

Senior/Staff Software Engineer - TypeScript, AI & AWS

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.

During your first three months, you will become familiar with Vallor's platform and take ownership of clearly defined deliverables for a major enterprise customer. You'll work closely with internal and customer stakeholders to implement the functionality they need.

Over time, you'll move beyond the initial roadmap: identifying unmet needs, proposing solutions, improving the platform's architecture, and helping Vallor scale its product and engineering organization.

• 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

Employment type: Contractor or Contract-to-Hire
Location: Remote - Europe preferred; exceptional candidates considered globally
Compensation: Target range of USD $100,000-$140,000 annually, with flexibility up to approximately $200,000 for exceptional talent

Our client operates in a highly AI-native development environment, with the majority of code produced through AI-assisted workflows. Engineers are expected to go beyond basic autocomplete or occasional chatbot use.

The right candidate will know how to direct coding agents, break work into parallel streams, evaluate generated implementations, detect subtle problems, and ensure that every contribution meets production standards. The engineer-not the AI tool-remains accountable for the quality and correctness of the final product.
