Backend Engineer

About the role

Movable Ink scales content personalization for marketers through data-activated content generation and AI decisioning. The world’s most innovative brands rely on Movable Ink to maximize revenue, simplify workflow and boost marketing agility. Headquartered in New York City with close to 600 employees, Movable Ink serves its global client base with operations throughout North America, Central America, Europe, Australia, and Japan.

We’re looking for a Mid-Level Software Engineer to join the Behavioral team, responsible for turning raw customer signals into meaningful marketing triggers. This team builds the behavioral intelligence layer of our platform—systems that detect patterns in customer activity and inactivity (such as cart abandonment, price drops, or loyalty milestones) and translate them into automated messaging opportunities.

This is a hands-on role where you will contribute to the architecture and implementation of critical platform capabilities. You’ll design robust systems, write high-quality code, and ensure our services are scalable, reliable, and maintainable.

You’ll work on challenging distributed systems problems involving high-volume event data, event correlation, temporal windows, stateful evaluation, trigger eligibility, account-specific readiness, idempotency, reliability, observability, and downstream activation. The systems you help build will power use cases like cart abandonment, browser abandonment, checkout abandonment, price drops, back-in-stock alerts, loyalty milestones, replenishment reminders, and audience membership changes.

You will report to the Behavioral Team Engineering Manager in this role.

What You’ll Do

- Contribute to Behavioral Platform Design and Implementation: Design and implement services that detect behavioral patterns across events, correlate signals across time windows, and determine trigger eligibility.

- Build Systems with Stateful Context: Build systems that maintain the behavioral state and lookback windows needed to evaluate patterns such as “action without completion”, multi-event intent signals and state-change-driven triggers.

- Own Feature Delivery: Act as a responsible hands-on contributor who delivers complex backend features from technical design through implementation, testing, deployment, and production support.

- Establish a Reusable Pattern Framework: Develop declarative or rule-based capabilities that allow new behavioral triggers to be defined, configured, evaluated, and extended efficiently.

- Partner Across the Platform: Collaborate with Product and engineering teams to ensure behavioral signals integrate cleanly into campaign orchestration and message delivery systems.

- Drive Operational Excellence: Ensure Behavioral services operate reliably at scale. Use observability, metrics, traces, logs, and alerts to maintain system quality and shared on-call responsibilities.

What You Bring

- 3+ years of professional software engineering experience, with a solid track record of building and operating backend or platform systems in production.
