Full Job Description

Senior Full-Stack Engineer (AI-Augmented)

We're building a high-impact SaaS platform and looking for an exceptional engineer to join a small, high-output engineering team. You don't just write code. You ship entire systems, fast, by combining deep technical skill with mastery of AI-assisted development tools. Working alongside our engineering manager and a fellow engineer, you'll be expected to produce at a level that rivals a much larger team.

What you'll do

You'll own large portions of the platform end-to-end: designing architecture, building backend services, standing up data pipelines, crafting frontend experiences, and deploying it all to production. As part of a lean three-person engineering team, your individual output matters enormously. You'll use AI tooling aggressively to move at a speed and volume that would traditionally require multiple engineers.

What we're looking for

Expert-level proficiency in Next.js with TypeScript. You build fast, type-safe, production-grade frontends without hesitation
Expert-level proficiency in Express.js (JavaScript) for backend API development, including routing, middleware, authentication, error handling, and performance tuning
Strong AWS experience, including deploying and managing backend services on EC2 or equivalent compute infrastructure, with comfort across networking, security groups, and scaling
Hands-on experience with AWS Amplify for frontend hosting and CI/CD
Strong PostgreSQL skills, including schema design, complex queries, indexing, and migrations using Prisma as the ORM
Experience with DynamoDB for high-throughput messaging and event-driven data patterns
Demonstrated ability to use AI coding tools (Cursor, Claude Code, Copilot, etc.) to dramatically accelerate your output. Not as a crutch, but as a multiplier on already-strong fundamentals
Experience integrating LLM APIs and building AI-powered features into products
Comfort operating autonomously with minimal oversight. You know when to make a call and when to ask

Nice to haves

Experience with multi-agent or pipeline-based AI architectures
Familiarity with infrastructure-as-code (Terraform, CDK)
Experience with additional AWS services (SQS, Lambda, S3, CloudFront, IAM)
Prior startup or small-team experience where you wore many hats

Why this role

This isn't a seat on a bloated team. You'll join a tight, senior engineering group where every person has outsized ownership and influence over a product with a large addressable market. We value output over headcount, and we're betting on a small number of exceptional builders who use every tool at their disposal, especially AI, to punch well above their weight. If you thrive with autonomy and want your work to actually matter, this is your environment.

Pay: $100,000.00 per year

Benefits:

401(k)
Bereavement leave
Dental insurance
Flexible spending account
Free parking
Health insurance
Health savings account

Lunch & learns
