Founding Engineer · Frontend

The hardest part of shipping autonomy is not the model, it's trust. Operators need to see what an agent is about to do, step in when they want to, and walk away when they don't. That confidence is built or lost in the interface.

As a founding frontend engineer, you own the surface where humans and agents share the work. You'll set the design-engineering bar for SAGARIS: interfaces that are fast, honest about state, and quiet enough that a revenue team can run their day through them.

• Build the core product surfaces, the inbox, the pipeline, the agent-supervision views, with craft and speed.
• Turn a dense, real-time system into interfaces that feel calm: clear state, no surprises, no dead ends.
• Own performance as a first-class concern, perceived latency is part of whether people trust an agent.
• Partner tightly with design to raise the bar on interaction detail, motion, and accessibility.
• Establish the frontend architecture, component system, and conventions the team builds on.

• You've shipped complex, stateful web apps that people use all day, and sweated the details.
• Deep React and Type Script fluency; strong instincts for component architecture and state.
• You care about accessibility, keyboard flows, and motion as craft, not check boxes.
• You can move from a rough idea to a shipped, polished surface without heavy direction.
• 0→1 or early-stage experience, or a clear appetite for that kind of ambiguity.

• A design sensibility strong enough to improve a screen, not just implement it.
• Experience with real-time data, streaming UIs, or data-dense dashboards.
• Familiarity with our stack (Next.js, Tailwind, framer-motion).

• In 3 months: you've shipped a core surface that design partners use daily and rely on.
• In 6 months: the frontend architecture and component system let the team ship fast without regressions.
• In 12 months: 'it feels like SAGARIS' means something specific, and you helped define it.

• Meaningful founding equity, with a real stake in what you help build.
• Top-of-band cash compensation. We don't ask you to trade salary for story.
• Remote-first with deliberate in-person offsites; we optimise for deep work, not attendance.
• A hardware and home-office budget, plus whatever software makes you faster.
• Comprehensive health coverage and a genuinely respected time-off policy.
• Direct access to the founders and an outsized say in the roadmap and the culture.
