About the Job
Full-Stack Engineer
WickedFile · Atlanta, GA (Onsite) · Full-time.
Why this job exists:
WickedFile is the AI-powered AP automation platform for auto repair shops. Our founder spent 40 years running shops, lost $180K to parts theft in a single year, and saw the same leak happen across the industry.
We built the “leak detector” for the back office: invoices, repair orders, vendor statements, and credits reconciled automatically so owners stop quietly losing money they already earned.
Customers are recovering thousands of dollars per month within weeks of go-live. Demand is outpacing what our small team can ship, so we’re hiring.
The role:
You’ll work directly with the founders and a small engineering team. No middle layers, no ticket treadmill. You’ll ship features that customers feel immediately across backend services, ingestion pipelines, and the product UI.
We’re looking for a highly technical engineer who can help modernize the platform with pragmatic AI-native tooling. You should be comfortable improving legacy systems, introducing better architecture incrementally, and shipping production-grade AI features that create measurable customer value.
Our current stack is primarily:
- Node.js + Express services.
- Vue/Quasar frontend apps.
- MongoDB + Redis caching patterns.
- Document/OCR and message-driven processing (including Java/Spring components).
- AWS-hosted infrastructure.
What we’re looking for:
- 3-6 years building production software as a full-stack or backend engineer.
- Deep TypeScript fluency. We're not looking for someone "comfortable with TS" we're looking for someone who has opinions about discriminated unions, branded types, andexhaustive productive. never checks, and who writes the type system that makes the rest of the team
- Production AWS experience — ECS Fargate, ALB, IAM, CloudWatch. You've been on-call.
- Terraform import experience. Specifically: you've taken hand-managed infrastructure into Terraform without drift. This is a real skill and we'll ask about it directly.
- Strangler Fig or equivalent migration experience — you've used ALB weighted target groups (or similar) and cut over real traffic with mirroring and gradual ramp.
- MongoDB production experience (indexes, replica set behavior, the typical gotchas — not
just CRUD). - API contract discipline. You've used OpenAPI, you've run consumer-driven contract tests (Schemathesis, Dredd, Pact, or similar), you've done a contract-preserving rewrite.
- Clear technical judgment and ability to explain decisions.
If you want real ownership in a company where your code lands in customer workflows fast, this is that role.
What you’ll do:
- Ship features end-to-end across services and UI.
- Build and harden document ingestion and reconciliation pipelines.
- Own meaningful surface area: design, implement, support, improve.
- Partner with founders and occasionally join customer calls to close the loop between product and real shop pain.
- Raise quality bar: challenge weak assumptions and propose better paths.
- Modernize core services and internal tooling without disrupting customer workflows.
- Identify high-ROI AI opportunities (classification, extraction, anomaly detection, workflow. automation) and ship them end-to-end.
- Improve developer velocity through better architecture, observability, and automation.
- Evaluate where LLMs belong in the stack and where deterministic systems are the better choice.
We don’t care about pedigree. Degree, bootcamp, self-taught, career-switcher it’s all fine. We care about what you’ve built and how you think.
Bonus points:
- Startup experience on small teams with broad ownership.
- Experience in document processing, OCR, AP/accounting, or reconciliation workflows.
- Experience with LLM-assisted workflows and practical opinions about where they do/do not work.
- Experience owning production infrastructure and on-call quality.
What we offer:
- Salary: $80,000 - $100,000.
- Equity in a company already delivering measurable ROI for customers.
- Health, dental, vision.
- In-person team in Atlanta.
- Founder with deep domain experience and direct customer signal.
