Full Job Description

**This position is a direct hire for one of our clients. This is a remote position. Eligible candidates must currently reside in the US and authorized to work in the US without visa sponsorship.**

Our client is seeking a highly skilled and hands-on Lead Software Engineer to play a pivotal role in building and scaling a new API platform that will support strategic integrations with external SaaS partners. This is a unique opportunity to help define the technical vision, lead platform development efforts, and build a high-impact engineering function from the ground up. The role combines technical leadership, software architecture, and cross-functional collaboration in a highly visible initiative that will directly support business growth.

Primary Duties

Lead the design, development, and evolution of a partner-facing API platform.
Architect and maintain a well-versioned, secure, and developer-friendly public API surface with a focus on backward compatibility, authentication, rate limiting, and documentation.
Define and implement API architecture, standards, and best practices.
Provide hands-on technical leadership through architecture guidance, code reviews, mentoring, and engineering best practices.
Own the long-term technical strategy and roadmap for the platform.
Collaborate closely with product managers, project managers, and engineering teams across multiple platforms.
Lead and coordinate the work of distributed engineering resources, including international contractors.
Own production systems for partner APIs, including monitoring, observability, incident response, alerting, performance optimization, reliability, and operational readiness.
Drive integration efforts with external SaaS platforms and partners.
Help establish engineering processes, technical direction, and team standards as the platform grows.
Break down complex initiatives into actionable workstreams and translate business requirements and acceptance criteria into technical deliverables.
Develop project plans, coordinate resources, and drive timely delivery of key initiatives.
Contribute to architecture and technical decision-making across services and platforms developed in multiple programming languages.
Serve as both a technical leader and hands-on contributor during the initial build phase.

Qualifications

5+ years of experience developing web-based software applications, including experience leading or mentoring engineers.
Deep experience designing, securing, documenting, and operating REST APIs, including authentication, versioning, and lifecycle management.
Strong experience managing and supporting production systems.
Hands-on experience with AWS services, particularly API Gateway, ECS, and related cloud-native technologies.
Strong TypeScript development experience.
Demonstrated technical leadership and project coordination experience.
Ability to quickly become productive in unfamiliar codebases and technology stacks.

Experience managing live customer-facing systems, including monitoring, observability, incident response, and reliability engineering.
Strong communication skills and the ability to thrive in a fast-paced, evolving environment.

Nice to Have Skills

Experience working across multiple backend languages such as C#, Java, Go, Python, Ruby, Node.js, or TypeScript.
Experience designing and delivering public, partner-facing, or developer-focused APIs and supporting developer documentation.
Experience with Infrastructure as Code tools such as Terraform, CloudFormation, or AWS CDK.
Experience working within Agile, Scrum, or Kanban environments.
Experience with test automation, contract testing, and test-driven development.
SaaS platform experience.
Familiarity with web application security and API security best practices.
Experience leading distributed or global engineering teams.
