This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Software Developer, API in the United States.

This role sits at the core of a high-scale data and API ecosystem, where backend services power large volumes of search, identity, and data-driven products used by millions of users. You will design and build robust, high-performance APIs that integrate multiple data sources and external platforms, ensuring reliability and scalability across distributed systems. Working in a remote-first, engineering-driven environment, you will collaborate closely with product, QA, and DevOps teams to deliver impactful backend solutions. The position combines hands-on coding with architectural ownership, making it ideal for engineers who enjoy solving complex system challenges. You will also contribute to performance optimization, data workflows, and API reliability at scale. Clear communication, strong engineering fundamentals, and a passion for clean system design are essential in this collaborative and fast-paced setting.

• Design, develop, and maintain scalable RESTful APIs that power high-traffic applications and ensure reliable data flow across systems and third-party integrations.
• Build and optimize backend services, improving performance, query efficiency, and system reliability across distributed architectures and large datasets.
• Support data access and integration across SQL and NoSQL databases, ensuring consistency and scalability of core infrastructure.
• Collaborate cross-functionally with product, QA, and DevOps teams in Agile/Scrum environments to deliver end-to-end backend solutions.
• Develop and maintain API documentation, technical flow diagrams, and usage standards to support engineering alignment and adoption.
• Contribute to system design discussions, troubleshooting high-throughput issues, and improving observability and operational stability.

Candidates should bring strong backend engineering expertise with deep experience in API development, distributed systems, and data-intensive applications. A bachelor’s degree in Computer Science or a related field is required, along with 7+ years of software development experience focused on backend or web systems. You should have hands-on experience with search technologies (such as OpenSearch or Elasticsearch), SQL and NoSQL databases, and performance optimization in high-load environments. Familiarity with AWS or other cloud platforms is expected, along with exposure to API design, data ingestion, and system integration workflows. Experience with ETL processes or big data tools (Spark, Hadoop, Airflow, data lakes) is a strong plus. Knowledge of Ruby on Rails, JavaScript, or Node.js is also valued. Strong communication skills, analytical thinking, and the ability to collaborate across technical and non-technical teams are essential.
