Lead Product Engineer (Platform) | IDR 40-70m p/m + equity

We're hiring a Lead Product Engineer to own the platform that wraps our AI agents: the customer portal, the live meeting experience, onboarding, billing, admin, and reporting. This is a hands-on, player-coach role: you will eventually lead engineers, but first and foremost you ship. Most of what users and paying customers touch outside the agent conversation itself is yours — and much of it is driven directly by commercial needs, where a small, well-built feature can unblock a deal the same week it's requested.

While our Agent Core team obsesses over how the AI behaves, you obsess over everything around it: can a customer build, deploy, share, monitor and bill for their agents without friction? The platform is where Kulu stops being a clever demo and becomes a product a business runs on.

About Kulu

Kulu is a high-performance, high-bandwidth communication team. We run live daily standups, Slack constantly, and jump into huddles rather than letting long async threads develop. Product, engineering and commercial conversations overlap heavily. This suits people who enjoy working closely with highly engaged colleagues, talking through hard problems in real time, sharing unfinished work, and moving quickly as new information emerges. It's probably not the right environment if your ideal style is to receive a well-defined problem, disappear for the day, and communicate primarily through async updates. There will be focused individual work — but we optimize for the speed and quality of the team as a whole.

We are deliberately moving toward a more in-person culture in Bali, and this role will help build a high-performance office culture where exceptional engineers want to work.

Tasks

You will be the technical owner of the Kulu platform — responsible for turning product and commercial priorities into shipped, polished features, fast.

• End-to-end feature delivery — Take user stories from a conversation with the CEO to production: portal features, the meeting frontend, agent configuration and deployment flows, dashboards and reporting, org and seat management, plans and billing. You own the full slice — frontend, backend API, data model.
• Product judgment in the details — Many requests arrive as a sentence, not a spec ("highlight the Scale plan as most popular", "customers need escalation policies"). You fill the gap with judgment: what's the smallest version that's genuinely good, what edge cases matter, what will confuse a customer. You work directly with the founders and are expected to push back when a request is the wrong shape.
• Commercial responsiveness — Platform work is often deal-driven: a customer rollout blocked on an org-management feature, a compliance requirement, a pricing page change needed for a live negotiation. You triage these against roadmap work and ship the urgent ones in days, not sprints — without breaking things.
• Platform architecture — Keep the wrapper clean as it grows: clear API contracts with the agent engine, sane data models, feature-flagged rollouts, frontend code that the next engineer can extend. You inherit a working production system; your job is to make it better with every change, not to rewrite it.
• Quality without ceremony — We don't measure you on process. We measure you on whether platform features ship quickly and then don't come back as bugs. You decide where tests, flags and staged rollouts earn their keep.
• Leading the platform team — A full-stack engineer will join the team under you as we grow. You'll assign ownership, review work, give frequent feedback, and own the team's output and development.

What success looks like

The North Star: does the platform ship what the business needs, fast, at a quality that builds customer trust? Success in the first months looks like: you own the portal and meeting frontend confidently; feature requests move from ask to production in days or a small number of weeks; deal-blocking requests stop needing founder involvement to land safely; recurring platform bugs get fixed at the root; and the CEO steps out of day-to-day platform delivery entirely because you've made him unnecessary there.

Requirements

• Excellent full-stack engineering fundamentals: modern TypeScript/React on the frontend, production backend and API experience, comfort owning a data model
• Strong product judgment — evidence you can take an underspecified request and ship the right thing, not just the requested thing
• A track record of shipping fast in small teams without sacrificing quality; comfort being measured on outcomes, not tickets closed
• Ability to work directly with founders and commercial stakeholders, including pushing back with reasons
• High agency and ownership; experience guiding or mentoring engineers, or clear readiness to lead a small team
• Fluent/Advanced spoken and written English, with the ability to communicate confidently and professionally. Our company language is exclusively English.

We care far more about evidence you can do these things than titles. We're particularly interested in founding engineers, senior product engineers from small high-performing teams, and technical founders.

Nice to have (optional): Python; experience with real-time media frontends (e.g., LiveKit, WebRTC); billing and subscription systems (e.g., Stripe); analytics and feature flags (e.g., PostHog); experience building on or around AI products; relational databases (PostgreSQL).

What we are not looking for

This is unlikely to be right if you need a finished spec before you can start, prefer deep work on one layer of the stack only, see UX polish as a designer's job, are uncomfortable with priorities shifting when a customer conversation changes them, want a highly asynchronous low-communication environment, or measure your impact in story points rather than shipped product.

Benefits

• IDR 40–70m/month gross + 0.2–0.5% equity

Our Operating Principles:

• Always Be Hustlin' – Move fast, outwork the competition, stay scrappy.
• Relentlessly Curious – Reason from first principles, question assumptions and explore better ways.
• Super Pumped – Show relentless enthusiasm and drive.
• Make Magic – Create experiences that delight customers.
• Obsess Over the Details – Perfect the product experience, no matter how small.
• Big Bold Bets – Think big, take risks and go after huge, transformative opportunities.
• Ownership is Key – Own the outcome, not just the task.

We intentionally call this role Lead Product Engineer rather than Head of Product Engineering - we want someone who still identifies as a builder. For an exceptional person, there is a natural path toward heading the Platform team at increasing scale as Kulu grows.
