About the Role

DockYard is seeking a Senior Software Engineer with expertise in Elixir, Phoenix, and React for a contract engagement. This role involves building a new multi-tenant platform end-to-end, from backend to frontend. You will augment client teams, partner on feature development, consult on best practices, and collaborate on product delivery projects. The engagement is a greenfield MVP focused on a configurable and re-skinnable multi-tenant platform, requiring full-stack development including backend, frontend, and an internal admin console. Key concerns include unified user identity, data privacy, and integration with third-party platforms. The ideal candidate actively reduces complexity, ships simpler solutions, and thrives in environments with open direction.

Responsibilities

Work closely with Product, Design, Engineering, and business stakeholders to understand business goals and priorities, analyze product requirements, and collaborate on solutions.
Collaborate with the team to translate product needs into a development roadmap and assist with scoping, sizing, and project planning.
Design and build a Phoenix backend with a documented JSON API, and build the React frontend that consumes it, owning the contract on both sides.
Take an AI-generated frontend prototype built on synthetic data and turn it into a production application: assess what to keep, rebuild what needs rebuilding, connect it to live APIs, and refine the UX as real data and requirements land.
Build multi-tenant data models and tenant-scoped access patterns so a new brand client is a configuration exercise, not a rebuild.
Implement integrations with third-party commerce and content systems behind well-defined adapter interfaces, including outbound API calls, inbound webhook handling, signature verification, idempotency, retries with backoff, and graceful degradation when a partner is unavailable.
Work directly with external vendors, some without public API documentation, to establish integration paths, obtain credentials, and validate payload contracts.
Build background job pipelines (Oban) for asynchronous processing, reconciliation, and event capture that survive traffic bursts and partner outages.
Build internal admin and operations surfaces in Phoenix LiveView so non-technical client staff can publish content, manage campaigns, and segment users without a developer.
Move fluidly across the stack, from database and backend services to API design to frontend implementation, without waiting on a handoff.
Actively manage scope and complexity: recommend the simplest implementation that satisfies the requirement, flag gold-plating, and help the team make explicit build-now vs. defer decisions.
On staff augmentation projects, you will embed yourself within client teams to evaluate existing codebases, recommend improvements, mentor other engineers, or simply to increase velocity as a highly productive independent contributor.
Interface directly with clients, leaning on your deep industry experience and proven knowledge of Elixir and Phoenix, but always maintaining an inquisitive and consultative approach.
When not on client work, you will support internal projects or R&D initiatives, contribute to DockYard-approved open source projects, participate in cultural and/or technical activities, or hone your craft through professional development and mentorship.
Continually look for opportunities to document and share your knowledge with others.
You may be asked to travel on occasion.

Requirements

5+ years of experience working across the stack, from database and backend services to API and frontend development using modern technologies and practices
Production experience with Elixir & Phoenix
Experience designing and shipping JSON APIs and building the client applications that consume them
Professional experience with React and modern JavaScript tooling, and the judgment to take a rough or prototype-quality frontend to production quality
Demonstrated experience integrating third-party APIs and webhooks in production, including authentication schemes, idempotency, retry and error-handling strategies, and rate-limit handling
Strong PostgreSQL and data modeling skills, including modeling for multi-tenancy or other forms of row-level scoping
Experience with background job processing (Oban or equivalent) for asynchronous, fault-tolerant workflows
A demonstrated bias toward simplicity: you can point to times you cut scope, removed complexity, or chose the boring solution, and explain why it was the right call
Comfort working with ambiguity and making pragmatic decisions when requirements are still being resolved
Experience collaborating with cross-functional teams using Agile methodologies
Excellent written and verbal communication skills
Highly collaborative and value authenticity, equity, and empathy
