We build the systems
others can't handle.
Marquelabs is an advanced engineering collective. We design, build, and scale mission-critical software infrastructure for startups and enterprises who need more than just "clean code."
Trusted by engineering teams at
Engineers, not agencies.
We don't have account managers. You work directly with Senior Staff Engineers and Architects who understand your constraints.
Built on unshakeable principles
Our engineering culture is defined by what we refuse to compromise on. We believe that speed comes from quality, not shortcuts.
Reliability First
We assume everything will fail. Network partitions, API limits, downtime. We build systems that degrade gracefully and recover automatically.
Radical Transparency
No black boxes. We document every architectural decision, trade-off, and known debt. You own the IP, the code, and the knowledge.
Performance Obsessed
We optimize for milliseconds. From database queries to React renders, we believe that software should feel instant and responsive.
Secure by Design
Security isn't an addon. We implement SOC2-ready controls, audit logs, and principle of least privilege from the first commit.
CI/CD Excellence
We ship daily. Automated testing, preview environments, and zero-downtime deployments are standard in every project we touch.
True Partnership
We embed in your Slack. We join your standups. We don't just take tickets; we help shape the product roadmap with engineering insight.
Our technical toolkit
We choose boring, proven technologies for the core, and bleeding-edge tools where they provide competitive advantage.
Modern Full Stack
Backend & Data
Infrastructure
AI & Machine Learning
We build production-grade AI agents using OpenAI, Anthropic, LangChain, and vector databases.
From concept to core infrastructure
We don't just drop code and leave. We guide you through the entire lifecycle.
Discovery & Architecture
We map the domain, define the data model, and choose the stack. Output: A technical design document (TDD).
MVP Development
Rapid iteration. We build the core loops and get a functional product into staging. Weekly demos and feedback.
Production Hardening
Load testing, security auditing, monitoring setup, and documentation. Preparing for real user traffic.
Scale & Handoff
We train your team, optimize for scale, or continue as your fractional engineering department.
Join the collective
We are looking for senior engineers who are tired of bureaucracy and want to focus on pure building. Remote-first, async, high-trust.
