^{About the role}

[The seniority/title is determined by job-related skills, experience, and evaluation after the interview.] 

We’re hiring Product Builders to shape the future of marketing for agents — where AI agents are no longer tools, but active participants in how products are built, decisions are made, and value is delivered.

AI agents are fundamentally reshaping:

• how products are built (AI-native, faster, more iterative)
• how marketing flows work (agent-driven discovery, decisioning, and execution)
• how brands and customers communicate (from campaigns → conversations → autonomous interactions)

This shift unlocks a new wave of opportunities — to redesign workflows, reimagine user experiences, and build entirely new product categories.

This is not a traditional PM / designer / engineer / GTM role.

You’ll operate as a builder at the frontier, using vibe coding, AI tools, and rapid prototyping to explore and ship products in this emerging space. You won’t just define what to build — you’ll build, test, and evolve it.

 

What you’ll do

Build, not just define

• Design and ship products — where agents discover, decide, and act on behalf of users.
• Ship fast, learn fast — iterate based on simulation or real usage.

Own problems end-to-end

• Identify meaningful problems worth solving (clear “why this matters”).
• Drive from discovery → prototype → launch → iteration → scale.

Operate with high agency

• Don’t wait for perfect clarity — create momentum, test hypotheses, and move forward.
• Take ownership of outcomes, not just outputs.

Redesign how brands and customers interact

• Explore new interaction models: agent-to-agent, human-in-the-loop, and autonomous workflows.
• Reimagine marketing workflows as agent-driven systems, not static funnels.

Focus on what truly matters

• Identify the core 1–3 things that make the product valuable, and execute them exceptionally well.
• Avoid overbuilding — prioritize signal over noise.

Collaborate to ship impact

• Work closely with engineering, design, data, and GTM as co-creators.
• Continuously refine based on real-world feedback and data.

 

What we’re looking for

We’re looking for experienced, high-agency product builders who thrive in new, undefined spaces.

Core traits

• Builder mindset: you ship, iterate, and learn quickly.
• High agency: you don’t wait — you create momentum.
• Strong product taste: you know what good looks like and push toward it.

Experience

• 3–8+ years in product, engineering, startup, or builder roles.
• Experience shipping products end-to-end (0→1 or 1→n) with multiple showcases, with learning and problems to share.
• Exposure to AI-native products, LLMs, or automation is required.

Skills

• Comfortable operating in ambiguity and fast-changing environments.
• Hands-on with prototyping (no-code, low-code, or code).
• Strong prioritization and product judgment.

Mindset

• You believe the future is being built now — and you want to build it.
• You learn by doing, not waiting.
• You care about real customer impact.

 

Bonus points

• Experience with AI agents, agent workflows, or automation systems
• Familiarity with marketing automation, CRM, or customer engagement platforms
• Experience with building AI products
• Background in startups or 0→1 product environments
• Technical background (engineering, data, etc.)

 

Why join us?

We’re at the start of a major shift: From marketing to users → marketing for agents. The way products are built, how decisions are made, and how brands interact with customers is being rewritten — and we’re building at the center of it. This means:

• New product categories
• New interaction models
• New ways to drive ROI

There are countless opportunities to create value for our customers in this wave — and we’re looking for builders to explore and capture them.

 

What success looks like in the first 6 months

• You’ve shipped multiple prototypes or products in the marketing-for-agents space with business impact
• You’ve identified and validated at least one high-impact opportunity in this new paradigm
• You’re operating as a trusted builder, turning ideas into real outcomes
• You’ve helped redefine how agent-driven marketing workflows should work
• Your work has contributed to shaping Appier’s direction in AI agents and agentic marketing
