App Developer Jobs in Seattle, WA

Team Introduction

Possible exists to help everyday Americans build financial health — and our App Ecosystem team is the foundation that makes that possible at scale. We own the customer-level experiences and shared platform capabilities that every product at Possible builds on: the application flow, offer logic, shared services like identity verification, engagement and analytics tooling, and the composable frontend infrastructure that lets teams ship fast and safely.

This is a newly formed team, born out of a strategic reorg designed to solve one of our biggest challenges: Possible has grown from a single lending product to a portfolio of access products and services — but the infrastructure underneath was built for a one-product world. We're now building the connective tissue that turns a collection of individual products into a cohesive, multi-product platform that deepens customer relationships over time.

If you're energized by the idea of defining how a product-led fintech scales from "we have multiple products" to "we have a multi-product strategy," this team is where that work lives. You'll partner with a dedicated EM, a designer, and a team of 6-8 engineers — and the decisions you make will shape the experience for every customer and every product team at Possible.

The Role & Impact

As the Principal Product Manager for App Ecosystem, you'll own the shared frontend platform and customer-level infrastructure that every product team at Possible builds on. Your primary mandate is to define and scale the composable app foundation, shared services, and reusable patterns that make it safe and fast for teams to ship. You'll partner with engineering to shape an AI-first developer platform that enables both human engineers and AI agents to deliver frontend changes with confidence.

You'll own the product-agnostic layer of the Possible experience: shared services like identity verification and authentication, engagement and analytics tooling (Amplitude, Braze), and the app infrastructure (build, test, deploy) that underpins everything. Your job is to make sure product teams can launch and iterate on new experiences without reinventing infrastructure or building bespoke solutions. You'll define the standards, guardrails, and reusable building blocks that accelerate delivery across the organization.

This platform work directly enables Possible's most important strategic shift: moving from a single-product company to a multi-product platform. You'll lead the transition from our current model to a product-agnostic application experience, defining how customers access and move between products. You'll build the offer management system that determines what to present to each customer and allows non-engineering configuration of offers across channels and partnerships. And you'll develop the customer value optimization strategy that governs pricing, packaging, and product deepening across the portfolio.

This role reports directly to the Director of Product, has visibility across the entire product organization, and influences nearly every customer-facing decision at Possible. It will grow as the platform grows. If you build this well, you'll have built the system that Possible scales on for years.

What You'll Bring

Must-Have Competencies

• Platform thinking with customer empathy. You can toggle between "how do I build a system that product teams can leverage" and "what does this actually feel like for the customer." You've worked on products that serve both internal teams and end users, and you know how to balance those needs.

• Technical fluency with platform and infrastructure concepts. You don't need to write code, but you credibly partner with engineering on architecture, tooling, and developer experience decisions. You understand trade-offs around composability, reusable patterns, and what makes a platform safe and fast to build on.

• Strong analytical and data skills. You build analyses yourself, defining segmentation, measuring impact, and making trade-off decisions with data, not just intuition. You're comfortable in SQL, spreadsheets, and analytics tools, and you use them daily.

• High ambiguity tolerance and ownership drive. This is a new team with a greenfield mandate. There is no existing playbook. You thrive when you're defining the "what" and "how" from scratch, making decisions with imperfect information, and driving work forward without waiting for direction.

• Customer value optimization experience. You've made product and pricing decisions that optimize for customer lifetime value across multiple products or services. You understand the economics of what to offer, to whom, and when — not just feature shipping, but the strategic layer above it.

Preferred Competencies

• Experience building multi-product or marketplace frameworks. You've been through the transition from single-product to multi-product at a consumer company and understand the organizational, technical, and product design challenges that come with it.

• Experience with offer management, decisioning, or personalization systems. You know how to build a system that decides what to show a customer and allows non-engineering configuration of offers — understanding concepts like decisioning logic, audience targeting, and offer lifecycle management.

Nice to Have

• Consumer lending or fintech experience. Domain familiarity with credit products, underwriting, and regulatory considerations would accelerate your ramp, but the core skill is customer value optimization, which transfers across domains.

Key Behaviors We Value

At Possible, we live by our Cultural Values. For this role, we especially value:

• Act with Ownership. This is a new team with a greenfield mandate — no playbook, no predecessor to follow. You'll take personal responsibility for defining the multi-product strategy, making bold bets on architecture and customer experience, and driving outcomes with focus, urgency, and discipline. You'll think beyond your own tenure, building systems that Possible will scale on for years.

• Scientific Approach. The multi-product framework, offer management system, and deepening strategy all require rigorous thinking — forming hypotheses, running experiments, and changing direction when the data says so. You'll bring intellectual honesty to trade-off decisions and foster respectful debate with engineering, design, and cross-functional partners to ensure the best ideas win.

• Mission-Driven. Every decision you make — from product-agnostic application flows to offer decisioning logic — directly shapes how customers access and deepen their relationship with Possible. You'll obsess over the customer experience and make trade-offs that prioritize long-term customer value over short-term convenience.

This is a Hybrid position. We work in our centrally located office in downtown Seattle three days a week (M, T, and Th).

The compensation range for this role is $202,300 to $238,000. We also offer significant stock options, comprehensive benefits, a bonus plan, commuter benefits, and an excellent office space with complimentary drinks and food options.
