We’re looking for a Full-Stack Developer for a US-based product company building a B2B SaaS platform for the connected-home industry. The role offers end-to-end ownership, real product impact, an AI-native approach, and direct collaboration with engineering leadership.

What you'll do

• Own one or more meaningful product domains (think: AI agents, payments, public API, real-time engine, etc.) from architecture through rollout
• Drive system design decisions on our AWS serverless stack: data model, API shape, multi-tenant isolation, performance, observability
• Write production code across the stack: backend (Lambda, AppSync, GraphQL, Postgres) and frontend (React, MUI)
• Build with AI as a first-class material: LLMs, prompt engineering, RAG, agentic workflows. Push us toward smarter product and smarter ways of working
• Raise the bar through code reviews, RFCs, ExecPlans, and the standards you set by example

What we're looking for

• 5+ years building production software for customers.
• Strong architectural decision-making and system design. You've owned non-trivial systems through multiple releases
• Track record of driving complex, end-to-end features with visible product impact, not just refactors or incremental improvements
• Working fluency with AI technologies: integrating LLMs into real products, with hands-on experience in prompt engineering, vector databases, and RAG
• Product sensibility: you care about UX, speed, and polish, and you push back when something doesn't feel right
• Comfortable working without heavy PM overhead; you can shape the problem, not just implement a solution
• High ownership mentality. Self-directed, full-lifecycle builder who takes a feature from idea to shipped
• Excellent written communication. Most of our work happens async, in writing (PRs, RFCs, ExecPlans, Slack threads)

Bonus points

• Scaling GraphQL APIs with AppSync or Apollo
• Observability practices in AWS/Sentry (CloudWatch, metrics, alarms, structured logging)
• Shipping B2B SaaS that handles sensitive data: payments, PII, multi-tenant isolation
• Building agentic systems or production AI features beyond a basic LLM call
• Experience at a startup or a company with a genuinely high engineering bar

Our stack

You aren't expected to have shipped everything below, but you should be excited to work close to most of it.

• Language: TypeScript end-to-end
• Frontend: React, Material UI, Vite, GraphQL clients
• Backend: Node.js Lambdas, AppSync (GraphQL), a Hono-based REST Public API, EventBridge, SQS, DynamoDB
• Data: Postgres (Aurora), tsvector-based full-text search, real-time sync engine over WebSockets
• Infra & Observability: AWS, CDK, Sentry, CloudWatch
• Tooling: pnpm + Nx monorepo, Vitest, Playwright, Linear, Slack, Notion, Claude Code

How we work

• Minimum bureaucracy, direct access to leadership. No meeting overhead for its own sake. You'll work directly with the Head of Engineering and other leaders on what matters. The rest of the time is for building.
• Six-week cycles. We plan and ship in six-week cycles, with a cooldown between. Long enough to do something real, short enough to course-correct.
• Engineers own domains end-to-end. From architecture through rollout and ongoing health. No throwing things over the wall.
• We reprioritize when the business and our customers need us to. Plans are a tool, not a contract. If a partner problem or a market shift changes what matters most, we move.
• Code improvements are encouraged, not negotiated. If you see something worth fixing inside your domain, fix it. You don't need a ticket to clean up as you go.
• Async-first, writing-first. Most decisions happen in PRs, RFCs, ExecPlans, and Slack threads. Meetings are for things writing can't do.
• Small team, high trust, high bar. You'll have real autonomy and real accountability. We assume good intent and direct communication.
• AI-native by default. We use AI tooling (Claude Code, Cursor, Linear, etc.) across the team. We expect every engineer to be fluent and opinionated about where it helps and where it doesn't.

Responsibilities

• Design, develop, test, and maintain full-stack web applications.

Company: QAIL AI (qail.ai) 
Team: Founding Engineering Location: Remote (US time zones preferred) 
Type: Full-time · Senior/Lead

About QAIL

QAIL is building the intelligence layer for the agentic web. We detect and verify the AI agents and bots hitting our customers' websites in real time, qualify legitimate buying intent, and expose MCP endpoints that let autonomous agents discover and transact with businesses. Our detection runs at the AWS edge on CloudFront and Lambda@Edge, processes high-volume traffic with sub-second latency, and closes the loop back to ad platforms through Click ID attribution.

We're a small founding team moving fast on a category that's forming right now. You'll have real ownership over the systems at the core of the product.
 

The Role

We're looking for a senior/lead full stack engineer with deep backend strength to own — and set technical direction for — our edge detection and signal pipeline: the part of QAIL that sees every request, fingerprints it, and decides in milliseconds whether it's a human, a known AI agent, or something trying to look like one.

This is a high-throughput, low-latency problem. You'll be comfortable thinking about request volume, p99 latency, and the difference between what you can compute at the edge versus what belongs in the aggregation layer. As one of our most senior engineers, you'll make the architectural calls, set the standards the team builds against, and mentor as we grow. You'll touch frontend too — the customer dashboard and our embeddable detection script — but the center of gravity is backend and edge infrastructure.

What You'll Do

• Build and own detection at the AWS edge (CloudFront + Lambda@Edge): User-Agent and ASN matching against published AI provider ranges, TLS fingerprinting (JA3/JA4), and request-shape signals — all before the page is served.
• Design the signal aggregation pipeline that fuses edge signals, server-side behavioral data (timing, path depth, headers), honeypot/pixel hits, and fingerprint consistency into an identity and intent decision.
• Engineer the system to handle large traffic volumes reliably and cheaply — latency budgets, backpressure, caching, and graceful degradation under load.
• Build and maintain our MCP endpoints and attribution API that close the loop between agent activity and the customer's ad platforms.
• Develop the embeddable client script (fingerprint capture, form integration) and contribute to the real-time analytics dashboard customers use to see bot traffic and lead quality.
• Set technical direction — own architecture decisions, establish engineering standards, review code, and mentor engineers as the team scales.
• Make pragmatic architecture calls appropriate to our stage — ship, measure, iterate; no premature microservices.

Our Stack

• Backend: Java (primary) for core services and the signal pipeline; Python a plus. Edge functions (Lambda@Edge / CloudFront Functions) run in JavaScript/Node and Python.
• Edge: AWS CloudFront, Lambda@Edge
• Detection signals: TLS/JA3/JA4 fingerprinting, ASN/IP reputation, behavioral & timing analysis, browser fingerprinting
• Protocols/APIs: MCP (Model Context Protocol) endpoints, REST, Click ID attribution feedback
• Frontend: Modern JS/TS, React-based dashboard, vanilla JS/TS embeddable scripts
• Infra: AWS-native; managed services over self-hosted where the cost delta is modest

What We're Looking For

• 7+ years of backend engineering, with a track record building high-traffic, latency-sensitive systems (APIs, pipelines, or real-time services at scale).
• Strong proficiency in Java (our primary backend language); Python a plus, plus comfort writing edge functions in JavaScript/Node or Python (Lambda@Edge / CloudFront Functions) and working across the full stack.
• Hands-on experience with AWS edge / serverless (CloudFront, Lambda@Edge, Lambda) — or deep CDN/edge-compute experience you can transfer quickly.
• Strong grasp of HTTP, TLS, networking, and request lifecycle fundamentals.
• Demonstrated technical leadership: owning architecture, setting standards, and raising the bar for engineers around you.
• A pragmatic, ownership-driven mindset suited to an early-stage team: you scope, build, and ship end to end.

Bonus Points

• Background in bot detection, anti-fraud, ad tech / mar tech, or web security.
• Familiarity with fingerprinting techniques (TLS, canvas/WebGL, behavioral) from either the detection or evasion side.
• Experience with MCP, agentic systems, or LLM application infrastructure.
• Startup experience strongly preferred — you've thrived in an early-stage, high-ambiguity environment before.
• Big plus if you've been a startup founder yourself — you know what it takes to build from zero and own outcomes end to end.

What We Offer

• A founding-team seat in an emerging category, with influence over product and technical direction.
• High autonomy and direct ownership of core product systems.
• Remote-first, fast-moving, low-bureaucracy environment.
