LUNUL Systems Architect , NY LUNUL

From the founders of RBW, LUNUL is changing the residential lighting industry. Light shapes how we feel, governing our sleep, our mood, and our health—yet the industry remains profoundly broken, reliant on fragmented vendors and overly complex systems. We are building the first whole-home lighting ecosystem that combines proprietary controls hardware with the world's best partner lighting brands (starting with RBW and Arkoslight) to deliver cinematic, natural light that intuitively anticipates daily life.

We are a fast-growing startup on a mission to bring light into harmony with human rhythms.

You will own the complete technical architecture of a connected consumer electronics platform — from power electronics and embedded firmware through wireless communication, cloud infrastructure, and end-user applications. This is the most senior engineering hire on the team and the single point of accountability for how every layer of the system works together as one product.

We are building a multi-component hardware platform where the quality of the experience depends entirely on the integration between physical devices, local intelligence, and cloud services. The product surface is wide, the reliability bar is absolute (this is a product people live with daily), and the margin for “it mostly works” is zero. You will define the architecture that makes the system coherent, certifiable, manufacturable, and shippable.

• Define and enforce the interfaces across every boundary in the stack: MCU firmware analog/power stages, device hub communication (wired and wireless), edge compute cloud services, cloud mobile and web applications, and third‑party integration protocols.
• Own the system behaving as a unified product, not a loose federation of subsystems.
• Lead design reviews and make trade‑off decisions across functions. Surface and resolve cross‑domain design issues before they block progress.

• Drive technology selection decisions in collaboration with product and sourcing leadership.
• Every component, module, and service choice has cost, timeline, and IP implications — you own the technical rationale and present clear recommendations, not open‑ended options.
• Know when to roll custom for competitive advantage and when an off‑the‑shelf solution gets us to market faster without compromising the architecture.

• Work directly with electrical and mechanical engineers on board‑level architecture decisions — processor selection, power distribution topology, sensor integration, and signal chain design.
• Ensure that firmware architecture supports OTA updates, graceful fault recovery, field diagnostics, and long‑term maintainability from day one.
• You don’t need to lay out the PCB, but you need to understand the consequences of every major hardware decision on the software that runs on top of it.

• Own the regulatory strategy across the full BOM.
• Structure the design so that UL 8750, FCC Part 15B, NEC Class 2, and any application‑specific safety requirements are met by architecture — not patched in during pre‑certification testing. You are experienced in regulatory submission and know what “designing for certification” actually means at the schematic level.

• Maintain component‑level visibility into supply chain exposure, single‑source dependencies, lifecycle status, and cost.
• Flag end‑of‑life and allocation risks before they become production problems.
• Manage component alternates proactively. Work with manufacturing partners to ensure the BOM is producible, testable, and cost‑effective at target margins — in our business, the architecture decisions you make are the gross margin.
• Define the services layer — device provisioning, telemetry ingestion, remote diagnostics, OTA delivery, and any machine learning or behavioral intelligence pipelines.
• Architect the data model and APIs that serve both consumer‑facing applications and any professional/installer tools required for deployment, commissioning, and support.

• Design the security model end to end: device…
