About The Position

Saga is building a new category: AI-native characters that form synthetic relationships with people across digital platforms. Agents on our B2B2C platform appear as AI-native characters across social platforms, where they create content, respond to fans, build ongoing relationships, and drive measurable outcomes - from community growth and user acquisition to downloads, in-game purchases, subscriptions, sales, and long-term engagement. We believe the next generation of brand and game interaction will not be static content or one-off campaigns. It will be persistent AI characters that know their audience, remember context, evolve over time, and move across social, games, and interactive worlds. We are an early-stage team building with design partners in gaming, entertainment, and consumer brands. The product is moving from social-first AI character deployments toward a repeatable platform that brands and studios can launch, manage, measure, and scale.

Requirements

• Understand social products deeply: Experience with consumer social, UGC, or engagement-driven platforms; strong intuition for what drives retention, attachment, and habit formation.
• Have built AI-native products: Experience with LLMs, agents, or conversational systems; comfortable working with model behavior, prompting, evals, and iteration loops.
• Have taste for “relationship dynamics”: Notice when interactions feel authentic vs. mechanical; think about tone, timing, memory, and emotional continuity; care about how users feel —not just what they do.
• Think in systems: Naturally reason about memory, state, constraints, and failure modes; can turn messy AI behavior into structured, scalable primitives.
• Be technical enough to go deep: Can partner closely with engineering on architecture and tradeoffs.
• Thrive in early-stage environments: Comfortable with ambiguity and fast iteration; can add structure without killing speed.
• Be a growth/product/business operator, not just a character AI thinker: Know how to connect user behavior, product quality, customer value, and revenue impact; comfortable owning KPIs such as engagement, retention, UA efficiency, conversion rate, campaign ROI, downloads, purchases, subscriptions, and customer expansion; can balance product vision with the discipline required to build a B2B platform customers will buy, trust, and renew.
• Understand B2B customers and enterprise buying dynamics: Can work with brand marketers, game studios, UA/growth teams, community teams, and executive stakeholders; understand the difference between a compelling demo, a successful pilot, and a repeatable product customers can adopt at scale; can support customer discovery, pilot design, roadmap tradeoffs, pricing/packaging input, and GTM learning.
• Built AI-native, data-driven, technical, or highly ambiguous products.
• Experience at social platforms (TikTok, Instagram, Reddit, etc.).
• Strong product judgment around user behavior, engagement loops, retention, and growth.
• Ability to work deeply with engineering on systems, architecture, tradeoffs, evals, and constraints.
• Experience translating customer needs into platform primitives and repeatable workflows.
• Ability to operate in a zero-to-one startup environment where strategy, execution, customer learning, and product process all need to happen at once.

Nice To Haves

• Enterprise SaaS, marketing technology, customer engagement, CRM, community, or growth platforms.
• AI companions, chatbots, character AI, conversational agents, or agentic systems.
• Gaming, interactive storytelling, game publishing, community management, UA, or live operations.
• Consumer social platforms, creator economy, UGC, influencer marketing, or social distribution.
• Developer tools, APIs, integrations, analytics platforms, or self-serve customer tooling.
• Prior engineering background or highly technical PM experience.
• Experience with AI companions, chatbots, or character-based products.
• Founder or early-stage startup experience.
• Experience with brand marketing, game publishing, UA/growth, customer engagement, or enterprise SaaS.
• Experience building analytics, attribution, experimentation, moderation, or compliance products.

Responsibilities

• Define relationship-first product strategy: Design how AI characters form and maintain ongoing relationships with users, shape interaction models across social platforms (content, replies, DMs, presence), identify what drives retention, attachment, and repeat engagement, translate relationship quality into measurable customer outcomes (engagement, community growth, user acquisition, conversions, revenue impact, and long-term fan value), and define which use cases Saga should serve first across brand marketing, gaming, social engagement, and UA/growth teams.
• Build AI-native character systems: Own core primitives like memory, personality, continuity, and voice; design how characters evolve over time and across contexts; partner with engineering on agent architecture and iteration cycles; turn loose AI behavior into scalable product primitives that customers can configure, evaluate, and trust; and define how character memory, persona, tone, goals, boundaries, and campaign context should work across channels.
• Drive product iteration & evaluation: Define what “good” looks like for a relationship with an AI character; build evaluation frameworks combining engagement metrics (retention, depth of interaction) and qualitative signals (believability, emotional resonance); rapidly iterate based on real user behavior; build the measurement stack for character quality, commercial performance, and customer ROI; define and improve KPIs including conversation depth, repeat interaction, retention, campaign performance, conversion funnels, downloads, purchases, subscriptions, and cost-effective UA; and create experimentation and analytics systems that show which characters, behaviors, campaigns, and channels are working.
• Lead social & content dynamics: Shape how characters behave on platforms (posting, responding, initiating); balance content creation vs. interaction; understand and leverage platform-specific dynamics (e.g., feed vs. DM vs. comments); define platform-specific playbooks for how agents should acquire attention, deepen relationships, route users toward actions, and avoid off-brand or unsafe behavior; and partner with customers and internal teams on campaign strategy, content loops, creator/IP dynamics, and social distribution mechanics.
• Evolve into a multi-platform system: Translate social-first learnings into game and interactive environments; define how characters persist across surfaces and contexts; help build a platform for studios and developers over time; define how agents move from social surfaces into games, websites, communities, apps, and interactive worlds while preserving memory, identity, and user context; and develop the product path from bespoke deployments to reusable platform capabilities, APIs, integrations, and customer self-serve workflows.
• Own the brand and studio platform: Own the product layer that allows customers to configure, launch, monitor, and improve AI characters across channels; build customer-facing tools for persona design, campaign goals, memory controls, approval workflows, analytics, safety settings, moderation, and performance optimization; define the platform primitives needed for brand marketers, game studios, and UA/growth teams to deploy agents without requiring bespoke engineering every time; develop workflows for campaign setup, content review, escalation, reporting, permissions, auditability, and customer success operations; and help the company move from high-touch service delivery to a scalable B2B product, with a path toward enterprise-grade capabilities.
• Own trust, safety, and governance: Design the product systems that allow AI agents to represent brands safely at scale; own product requirements for brand safety, user safety, moderation, escalation, disclosure, privacy, memory retention, consent, auditability, and compliance; partner with engineering, legal, policy, and customers to reduce hallucinations, off-brand behavior, manipulation risk, regulatory exposure, and platform policy violations; and build human-in-the-loop controls, review systems, safety evals, guardrails, and monitoring workflows that customers can trust.
• Lead customer discovery and platformization: Work directly with design partners, brands, game studios, marketers, and UA/growth teams to identify repeatable use cases; support pilots and early enterprise conversations by clarifying customer needs, product gaps, buying objections, and success criteria; translate customer-specific deployments into reusable platform primitives, roadmap priorities, and product requirements; and make hard tradeoffs between custom work, managed service delivery, and scalable platform investments.
• Own product strategy, roadmap, and operating cadence: Own Saga’s product roadmap and company-wide product strategy in partnership with the CEO and founders; create the product operating cadence for prioritization, discovery, delivery, experimentation, measurement, and post-launch learning; bring structure to an early-stage company without slowing down the speed required to win; and over time, help hire and lead product, design, research, and analytics talent as the company scales.
