About The Position

Sustainment is scaling fast and our engineering team has grown significantly and our delivery surface spans commercial SaaS product development and government-funded R&D programs. We are looking for a versatile Integration Engineer to serve as the technical bridge between Sustainment’s platform and our customers’ existing technology ecosystems.
This is a generalist role that blends software engineering, systems integration, and customer-facing collaboration. You’ll work directly with customers to understand their workflows, connect Sustainment to their ERPs, procurement systems, and other business-critical software, and help ensure seamless data flow across their operations.
The ideal candidate is someone who thrives at the intersection of technology and people, who is equally comfortable writing integration code, troubleshooting data mapping issues, and leading a technical discovery call with a customer’s IT teams.

Requirements

• 3+ years of experience in software engineering, systems integration, solutions engineering, or a similar technical generalist role.
• Demonstrated ability to work directly with customers in a technical capacity. You should have no issues leading a discovery call, presenting a technical solution, and following through on implementation. Consulting experience is a plus.
• Hands-on experience integrating with ERP systems or manufacturing/procurement software.
• Proficiency with APIs, data formats (JSON, XML, EDI, CSV, XLSX, etc.), and integration patterns (pub/sub, event-driven, batch ETL).
• Strong scripting and programming skills in one or more languages such as Python or JavaScript/TypeScript.
• Strong problem-solving instincts and comfort working across unfamiliar systems and codebases.
• Prior experience at a SaaS startup or high-growth technology company.
• Excellent written and verbal communication skills.
• To be eligible for this role you must be located in the Austin, TX metropolitan area and open to a hybrid work-schedule.

Nice To Haves

• Experience working in or with manufacturing, defense, aerospace, or industrial sectors.
• Familiarity with iPaaS platforms or middleware tools.
• Knowledge of EDI standards and B2B data exchange protocols.
• Experience with cloud platforms (AWS preferred) and containerized environments.
• Understanding of procurement workflows, supply chain operations, or MRP/ERP business processes.

Responsibilities

• Design, build, and maintain integrations between Sustainment’s platform and customer systems.
• Serve as a trusted technical point of contact for customers during integration onboarding, implementation, and ongoing support.
• Collaborate with customers to map data flows, define integration requirements, and translate business processes into technical specifications.
• Work with platform engineers to maintain APIs, webhooks, ETL pipelines, and middleware to support real-time and batch data exchange.
• Troubleshoot integration issues across diverse technology stacks and provide timely resolution to production problems.
• Work closely with Product, Engineering, and Customer Success teams to identify integration patterns, improve platform extensibility, and feed customer insights back into the product roadmap.
• Create and maintain integration documentation, runbooks, and knowledge base articles for both internal teams and customers.
• Evaluate and recommend third-party integration tools, iPaaS platforms, and connector frameworks as appropriate.
• Develop new AI focused internal tooling and automation that accelerates future integration delivery.
• Openness to travel

• Sustainment offers a competitive benefits package for full time employees including medical, dental, vision, paid time off, company holidays, and 401K matching.
