Senior Integration Engineer

Avenue Code is the leading software consultancy focused on delivering end-to-end development solutions for digital transformation across every vertical. We’re privately held, profitable, and have been on a solid growth trajectory since day one. We care deeply about our clients, our partners, and our people. We prefer the word ‘partner’ over ‘vendor’, and our investment in professional relationships is a reflection of that philosophy. We pride ourselves on our technical acumen, our collaborative problem-solving ability, and the warm professionalism of our teams.

Avenue Code has been believing in and promoting plurality actions for over 10 years, understanding that recognizing differences and fostering a safe environment, employment opportunities, representation, and support are the best ways to promote an increasingly equitable culture.

Avenue Code is seeking a Senior Integration Engineer to join a strategic engagement supporting a large enterprise retail client undergoing a broad marketing technology transformation. You will be part of a lean, senior-weighted engineering team owning the integration layer that connects a modern owned media platform stack — including CDPs, ESPs, and real-time data pipelines — across multiple consumer brands.

This role is central to the team's mission: owning the engineering plumbing that no one else owns, so that marketing and product teams can focus on experimentation and outcomes rather than infrastructure.

Responsibilities

Design and build CDP activation pipelines — including audience feeds, event streaming, and data quality checks between customer data sources and downstream marketing platforms

Own API integration architecture across vendor systems — define contracts, enforce SLAs, and build reliability patterns (circuit breakers, retry logic, dead letter queues)

Implement and maintain event streaming infrastructure using Kafka, Azure Service Bus, or comparable message queue / pub-sub systems

Build and maintain real-time data pipelines supporting audience delivery and experiment results into marketing data lakes

Monitor end-to-end integration health across the martech vendor ecosystem — proactive telemetry, alerting, and incident response

Partner with engineering and product teams to onboard new vendor integrations and manage the technical complexity of platform consolidation

Document integration patterns, data contracts, and API standards for internal developer use

Advanced or Fluent English

Enperience with integration or backend engineering experience, preferably in martech or data platform contexts

Strong API engineering skills — RESTful design, event-driven architecture, webhook/message queue patterns

Hands-on experience with Kafka, Azure Service Bus, or similar event streaming/pub-sub platforms

Experience building CDP activation pipelines — Amperity, Segment, or comparable; audience feeds and real-time event streaming

Familiarity with vendor integration patterns in martech ecosystems (ESPs, CDPs, tag management, attribution platforms)

Cloud-native development experience — Azure preferred; containerization, infrastructure-as-code (Terraform)

Strong understanding of data contracts, SLA monitoring, and observability practices

Nice To Have Skills

Experience with CDP-to-ESP data feed pipelines (e.g., Amperity to downstream activation platforms)

Familiarity with GCP data lake architectures (BigQuery, Pub/Sub)

Retail or e-commerce domain background

Exposure to feature flag systems or experimentation tracking pipelines
