Quant Job Offer: Founding Engineer (Full-Stack) Execution Systems at SwissBorg

Job Description

About Quant

Quant is an AI trading companion (Chrome extension) that surfaces pro trade setups (entry/SL/TP, P/L preview, backtested success score) across Hyperliquid perps and lets users execute in one click, non-custodially.

ABout XBorg

XBorg is a spin-off from SwissBorg and builds the AI infrastructure for personalized experiences. Its flagship product FanBase is used by some of the largest esports teams and gaming brands in the world, and it recently launched XBorgAI, an independent initiative exploring AI-native products across other emerging verticals, which led to the creation of Quant.

Role overview

We’re hiring a founding, full-stack engineer who thrives in startup environments and can own critical paths end-to-end: backend services, execution reliability, CI/CD, cloud infra, and the extension UI. You’ll ship fast, instrument everything, and lead the trading execution layer (low-latency, high-reliability) from internal beta to broader rollout. Your focus will be hardening execution, reliability, and scale. You’ll work directly with the founder; our technical advisor (founding engineer) supports architecture continuity during handover.

Responsibilities

Own the execution path: order orchestration, risk rails (SL/TP, slippage buffers, retries/backoff), error codes, incident playbooks.

Ship & scale the setup engine: integrate/optimize strategy adapters; serve ranked Top-3 setups with clear SLOs.

Full-stack delivery: TypeScript/Node REST APIs, Python workers & REST APIs, React/Chrome extension, NextJs frontend, Postgres.

Production reliability: observability (logs/metrics/traces), alerting, rate-limits, feature flags, kill-switch.

CI/CD & infra: Containerization (Docker), automated tests/deploys, IaC, secure secrets, staging/prod parity, cost-aware cloud.

Security & privacy: non-custodial flows, wallet interactions, principle of least privilege.

Roadmap collaboration: signal-provider marketplace, CEX integrations.

Representative Technologies

Backend: Node.js (TypeScript, Node 20), Python (async workers), WebSockets/REST, Postgres, Redis/queues.

Frontend: React Chrome Extension APIs, content scripts, overlay UI. NextJs

Cloud & DevOps: AWS (VPC, ECS (EC2), RDS), Docker, Terraform/CDK, GitHub Actions, Sentry/PostHog/Grafana.

Trading/Web3: Hyperliquid APIs (HyperCore), wallet flows, signing; additional exchange APIs later.

Qualifications

5+ years building and operating production systems end-to-end in startup environments.

Self-starter with founder mindset: clarify, design, ship, measure, iterate.

Strong in Python and Node.js/TypeScript; comfortable context-switching across the stack.

Hands-on across backend, CI/CD, cloud infra, and frontend.

Pragmatic testing: unit/integration, load testing for execution paths, telemetry-first approach.

Solid engineering hygiene: reviews, documentation, security, and calm debugging under pressure.

Bonus Experience

Blockchain engineering (wallets, signing, EVM/HL or similar) and/or financial markets/exchange systems.

Chrome extension performance & permission model expertise.

Low-latency systems, back-pressure, numeric stability (PnL/ATR/RR).

Zero-to-one product launches and ownership of on-call.
