Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and build the integration layer connecting AI agents to third-party services like email, calendars, and productivity tools. Own the full lifecycle of integrations, including authentication, API clients, and tool protocols for reliable agent interaction.
Requires 5+ years of software engineering experience with a strong focus on backend fundamentals and building scalable integrations. Candidates should have expertise in API design, OAuth, and a deep understanding of how tool-use schemas affect LLM behavior.
Hark is an artificial intelligence company building advanced, personalized intelligence. One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory.
We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines. While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world.
To get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems.
You'll build and own the integrations layer that makes Hark's AI agent genuinely useful in the real world. That means connecting it to the tools, services, and data sources people actually use every day.
That means designing and shipping the protocols, connectors, and execution primitives that let Hark take real actions: reading and writing email, managing calendars, interacting with third-party APIs, and coordinating across services on a user's behalf. The power of an agentic system is only as broad as what it can reach.
This is a high-ownership role on a small team. You'll work directly with platform engineers and model researchers, and the integrations you build will define the boundaries of what Hark can do.
The US base salary range for this full-time position is between $170,000 - $400,000 annually.
The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.
Building the Intelligence Behind the Next Generation of Products.
Hark Labs is a GenAI and product innovation studio helping startups and enterprises harness the power of artificial intelligence. We design smarter products, automate complex workflows, and turn data into dynamic intelligence — bridging the gap between cutting-edge AI research and real-world business impact.
