Full Stack Software Engineer

STLabs is an AI service management platform that resolves employee requests end-to-end, grounded in a living model of the enterprise. This matters because we're able to resolve requests with full context - the people, systems, services, and policies that define how an organization actually runs. Requests that used to take days of back-and-forth resolve in minutes, right where employees already work.

About the Role
We are seeking Full Stack Engineers with deep experience designing and building enterprise-grade applications. You’ll be responsible for building user-facing features and backend services end-to-end, collaborating closely with designers, product engineers, and infrastructure experts.

Responsibilities

• Own features end-to-end: design, implement, test, and deploy user-facing functionality and backend APIs

• Shape the stack: work across front-end, backend, and database layers (stack not set yet — you’ll help define it)

• AI-native product development: integrate AI/LLM capabilities into workflows to make ITSM smarter and more efficient

• Performance & scale: build highly performant, secure, and scalable services for enterprise customers

• Collaborate cross-functionally: partner with platform engineers on infrastructure, and with product/design on UX

• Developer productivity: contribute to internal tooling, code quality, and CI/CD best practices

• Security & compliance: bake in enterprise-grade security and compliance (SOC 2, ISO 27001) from day one

• Customer impact: deliver features that enterprise users actually love, in contrast to the legacy tools they tolerate

Qualifications

• Education: Degree in Computer Science, Engineering, or related field from a top-tier engineering school

• Experience: Full Stack Engineering (or Software Engineer with end-to-end ownership) in SaaS environments serving enterprise customers

• Frontend: Skilled with modern frameworks (React, Vue, Angular, or similar). Strong understanding of design systems and building clean, performant UIs

• Backend: Proficient in at least one modern programming language (Python, Go, Rust, C++ or similar). Experience designing REST/GraphQL APIs and distributed systems

• Databases: Hands-on with relational (Postgres/MySQL) and ideally non-relational or graph databases

• Cloud: Strong experience with AWS, GCP, or Azure

• DevOps: Familiar with CI/CD pipelines, Docker, Kubernetes, and IaC (Terraform)

• Mindset: Pragmatic, product-driven engineer who thrives in high-velocity startup environments

• Bonus: Experience building applications with AI/LLM integrations, or exposure to ITSM/enterprise workflows. Taking products from 0 to 1

What We Offer

• Build foundational product features for an AI-first enterprise platform

• The opportunity to take ownership of critical systems that scale to millions of users

• A culture that values craftsmanship, autonomy, and technical excellence

• Competitive compensation, equity, and benefits package

• Work from our Midtown, Manhattan office, where you’ll be side-by-side with the founding team in a supportive, collaborative setting. Our team works on-site five days a week, growing and building together, and the location is easy to reach with plenty of public transportation options.
