Socure is building the identity trust infrastructure for the digital economy — verifying 100% of good identities in real time and stopping fraud before it starts. The mission is big, the problems are complex, and the impact is felt by businesses, governments, and millions of people every day.

We hire people who want that level of responsibility. People who move fast, think critically, act like owners, and care deeply about solving customer problems with precision. If you want predictability or narrow scope, this won’t be your place. If you want to help build the future of identity with a team that holds a high bar for itself — keep reading.

At Socure, Software engineers work within product-focused teams to design and build systems that operate at scale and deliver meaningful, real-world impact. Our teams actively engage with customers to drive satisfaction and champion continuous improvement across our product suite.

As a Senior Backend Engineer, you will be responsible for leading the design and implementation of distributed systems, taking full ownership of critical non-functional requirements such as scalability, security, and reliability. You will mentor fellow engineers, provide technical expertise, and remain hands-on through all phases of development—from architecture and implementation, to testing, documentation, and production support.

This role is ideal for backend engineers who are passionate about building robust systems in Golang, thrive in a fast-paced environment, and want to shape technology at scale.

What you'll do:

• Architect, develop, test, and debug scalable backend services for distributed systems.
• Lead and deliver on key non-functional requirements, including scalability, availability, performance, and security.
• Design, author, and maintain comprehensive unit, integration, and functional tests to ensure reliability and exceptional coverage.
• Create and contribute to technical documentation, fostering knowledge sharing and collaboration across teams.
• Break down complex projects into clear, actionable tasks and drive them through to completion.
• Mentor and support team members with code reviews, technical guidance, and sharing best practices.
• Collaborate cross-functionally with product managers, designers, and engineers to deliver impactful features.
• Continuously improve engineering processes, tools, and practices within an agile environment.

What you'll bring:

• 5–8 years of professional software engineering experience with strong Golang proficiency, ideally in product-driven companies.
• Solid programming fundamentals, excellent problem-solving skills, and expertise in system design.
• Deep understanding of concurrency, multi-threading, and distributed computing concepts.
• Experience building microservice architectures and developing RESTful APIs.
• Demonstrated analytical and reasoning skills, with the ability to visualize and simplify complex systems.
• Experience working with high-throughput, low-latency systems is highly desirable.
• Familiarity with cloud platforms (AWS/GCP), NoSQL databases, big data analytics, or machine learning services is a plus.
• A growth mindset and a genuine desire to learn, improve, and help build leading-edge backend systems.
