AI Product Engineer

Pelago is the leading specialty substance use care provider, built on the belief that effective treatment means matching care intensity to what each member actually needs rather than defaulting to the most expensive intervention. Our programs guide members through every stage of the substance use spectrum, from unhealthy habits to active use disorders, delivering personalized treatment for tobacco, alcohol, opioid, cannabis, and stimulant use based on individual health, habits, genetics, and goals.

With Sona, our voice-first AI Mental Health Specialist, Pelago now applies that same clinically-driven model to mental health, pairing deep clinical expertise with technology to expand access without compromising care quality. We believe technology should make clinical care more precise and more human, not replace the judgment behind it.

Pelago has scaled to helping hundreds of employers and health plans and has already helped more than 750,000 members better manage their substance use. If you're passionate about AI and making an impact on the health of others, join us and make it happen!

About Pelago Engineering:

Our engineering team operates as empowered, outcome-oriented problem solvers, working in close partnership with product, design, and clinical teams to improve member outcomes at scale.

As AI transforms how software is built, we are intentionally evolving our development lifecycle so we spend less time on mechanical implementation and more time on system design, judgment, and impact.

How We Work:

Outcome-driven: Engineers are given problems to solve, not just features to build. Success is measured by learning, impact, and outcomes—not velocity alone

AI-native: We use AI across the SDLC to accelerate implementation, testing, and review. Engineers focus on defining intent, validating behavior, and designing resilient systems

High autonomy, high accountability: Teams have real ownership over their domains. With autonomy comes responsibility for quality, safety, and results

Cross-functional by default: Engineers partner deeply with Product, Design, Data, and Clinical. Discovery, experimentation, and delivery are shared responsibilities

Quality and safety matter: We build in a regulated, member-impacting domain. Reliability, observability, and correctness are first-class concerns

What You’ll Do:

Instead of task lists, anchor on ownership:

Own meaningful problem spaces end-to-end, from discovery through delivery and iteration

Design and evolve systems that support safe, scalable, AI-augmented development

Use data and experimentation to validate whether solutions actually work

Collaborate cross-functionally to balance member impact, clinical constraints, and technical tradeoffs

Shape how we work—our tools, processes, and culture

What We Look For:

We explicitly assess for empowerment:

You start with "why" before diving into "how"

You're energized by ambiguity and collaborative problem-shaping

You use AI to amplify your judgment and move faster on what matters

You think in systems and anticipate second-order effects

You want to own outcomes, not just ship features

Overview of the Role:

Pelago is building behavioral health care delivery from the ground up – AI-native, outcome-oriented, and built for a domain where what you ship has direct consequences for member health. Product Engineers own meaningful problems end-to-end: from discovery through production and iteration, in close partnership with product, design, data, and clinical stakeholders. The hire we're looking for is technically strong enough to ship across the stack, fluent enough with AI tooling to move fast, and grounded enough to make sound trade-offs in an environment where member safety, privacy, and reliability matter as much as speed.

This is a hybrid role with a high-collaboration rhythm (3 days/week in our NYC office).

In This Role You Will:

Own meaningful product areas end-to-end — from problem framing and prototype through production rollout and iteration.

Partner deeply with product, design, data, and clinical teams to shape solutions that improve member outcomes and business results.

Build and evolve secure, well-tested, observable software across backend, frontend, and data surfaces.

Use data, experimentation, and user feedback to validate whether shipped solutions are working, and drive iteration when they're not.

Operate autonomously in ambiguous environments, communicating proactively across globally distributed teams and functions.

Make sound trade-offs across speed, safety, technical quality, and maintainability in a regulated environment.

Improve Pelago's engineering system: AI-native development practices, testing, documentation, knowledge sharing, and review quality.

The Background We're Looking For:

Strong production experience building product software in a startup or scale-up environment.

Excellent TypeScript/Node capability; comfortable working across APIs, services, data and cloud infrastru…
