Senior Software Engineer (Contract) - Elixir

DockYard is hiring a Senior Software Engineer (Contract) with expertise in Elixir, Phoenix, and OTP.

Who We Are

DockYard is a remote-first, digital product consultancy. Forward-thinking teams come to us to build digital products that scale with their users, features, and complexity.

Using a candid approach to partnerships, we help to upskill teams along the way. The result? More flexibility in how our clients take products from idea to impact.

We don't just use innovative approaches to product development – we lead them. That's why visionary companies have trusted us to overcome complex product challenges.

We're honored to have been included in guides ranging from The Startup Weekly's Exceptional Workplace Award (2021), The BBJ's Fast 50 (2021, 2020), Inc. 5000 (2020, 2019), and Fast Company's Best Places to Work for Innovators (2020), among others.

The Role

DockYard is looking for a Senior Software Engineer with deep backend expertise in Elixir, Phoenix, and OTP to embed with a client team building mission-critical software. You will work across distributed real-time systems that process high-frequency data at scale, support complex planning and simulation workflows, and help manage a large asset tracking platform with hundreds of entity types.

This is a fully embedded engagement. You will join the client's engineering team directly, with their tools, badges, and workflows, operating as a core contributor rather than an outside advisor. The work is backend-heavy, centered on Elixir's strengths in concurrency, fault tolerance, and real-time data processing. The client's systems handle high-throughput monitoring across thousands of connected endpoints, coordinate across a large and varied asset inventory, and integrate with multiple external data sources that require bespoke parsing and reliable ingestion.

The ideal candidate is self-driven, passionate about building systems that operate reliably at scale, and stays current with Elixir and OTP best practices. They are collaborative but also comfortable working independently, and should feel empowered to thrive in environments with open direction and loosely defined requirements. They bring a strong product and consulting mindset to any team.

Responsibilities

Build and maintain backend systems in Elixir/OTP that process real-time monitoring and health data from thousands of connected endpoints.
Design and implement distributed data pipelines that ingest, normalize, and route data from multiple heterogeneous external sources.
Contribute to planning and simulation tools that support complex operational workflows.
Work on asset management systems that track and coordinate hundreds of entity types across diverse operational contexts.
Embed within the client's engineering team and collaborate closely with product, design, and business stakeholders to understand goals, analyze requirements, and deliver solutions.
Collaborate with the team to translate product needs into a development roadmap and assist with scoping, sizing, and project planning.
Evaluate existing codebases, recommend improvements, mentor other engineers, and contribute 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.
Support integration work with bespoke external systems and data formats that require careful parsing and reliable data handling.
Continually look for opportunities to document and share your knowledge with others.
You may be asked to travel on occasion, including periodic onsite work.
