About Junto

Junto is building the first truly secure, AI-native recruiting OS: where interview integrity, privacy, and automation are the foundation, not an afterthought.

We’re a brand-new team with deep recruiting and SaaS DNA, backed by early traction and a clear mission: help teams hire faster, safer, and with real trust.

This isn’t another ATS with an “AI layer.” Junto is a unified, compliance-ready platform built to solve deepfake fraud, regulatory pressure, and the chaos of 10+ disconnected tools.

What You’ll Do

• Architect, own, and ship the first real version of Junto, from greenfield to production (no legacy, all modern)
• Design and implement secure, scalable APIs, data models, and cloud infrastructure from scratch
• Lay the technical foundation: make early stack decisions, patterns, and workflows that future teammates will build on
• Work across the stack: focus on backend, but also spin up frontends (React), dashboards, and help with our first browser extension
• Ship fast, but with care: from ATS and CRM flows to live fraud detection and compliance automation
• Set the bar for code quality, docs, and CI/CD so onboarding the next wave of engineers is seamless
• Collaborate closely with the founders: your opinion matters on product, architecture, and team culture
• Lead by example: mentor new hires, run code reviews, and shape our engineering culture as we grow

What We’re Looking For

• 3+ years building SaaS or data-driven platforms from scratch (true 0-to-1, not just scaling)
• Strong experience architecting and building with Node.js/TypeScript, PostgreSQL, and AWS (or similar cloud)
• (Our default is modern JavaScript/TypeScript end-to-end for velocity and shared models, but if you bring a compelling technical vision and can deliver, you’ll have real influence.)
• Comfort with frontend (React): You can build, test, and ship UI, even if it’s not pixel-perfect. Front-end won't be your primary responsability as the team scales, but it may be required to handle some early frontend shipping.
• Security-first and privacy-by-design: Auth, RBAC, GDPR, and API security are familiar territory
• Startup mentality: You thrive on ambiguity, solve real problems, and do what needs to be done (not just what’s assigned)
• You care about what you build: You think about risk, performance, tradeoffs, and user impact, not just ticking off tickets
• Strong communication: Remote-first, async, clear writing and feedback are second nature

Bonus Points

• Experience leading or mentoring small teams (even informally)
• Built SaaS in regulated, security-heavy, or HRTech/FinTech domains
• Set up infra-as-code (Terraform/CDK), browser extensions, or integrated ML/AI APIs
• Interested in building out robust, human-in-the-loop AI features

Why Join Junto Now?

• You’ll own the foundation: Architect and deliver the core platform, not just maintain what’s there
• Immediate impact: What you build is what future engineers will work with. Your standards matter
• Direct access to founders: Product, not process, leads here. Your input changes the roadmap
• Very competitive salary: €35,000 to €50,000 gross/year, depending on experience
• Work from anywhere in Portugal: Óbidos HQ if you want, or fully remote with very occasional travel to the HQ (few times per quarter)
• No corporate layers: Real responsibility, real trust, real team

What’s Next for the Team?

You’re not building this alone. Over the following 3 months, we’ll be hiring:

• Back-End Engineer: To drive scalability, system design, and integrations
• Front-End Engineer: For UX/UI, browser extension, and polish
• ML Engineer: To deliver live fraud detection, AI Copilot, and data pipelines
• ML/Front-End Generalist: To support AI integration, data flows, and quick product experiments

Your role is to set the technical foundation, collaborate closely with these new hires, and help onboard and mentor them as the team rapidly grows.
