About The Position

The company is building an AI-native platform transforming how consumers engage with debt resolution and payments at scale. Their infrastructure powers millions of communications daily and supports over $1B in debt across a rapidly growing platform used by leading receivables and collections organizations. They’re looking for a Backend Software Engineer to help architect and scale the core systems behind the platform — from high-throughput microservices and event-driven infrastructure to AI-enabled workflows and agent tooling. This is a high-impact engineering role where every service you build directly influences revenue, platform reliability, and engineering velocity. You’ll work closely with product and engineering leadership in a lean, fast-moving environment where ownership is expected and execution speed matters.

Requirements

4+ years of experience in backend software engineering building scalable production systems
Strong experience building and owning microservices end-to-end in high-volume environments

Experience working in regulated industries such as fintech, payments, healthcare, or other compliance-heavy domains
Strong product and systems thinking with ability to independently define technical requirements and edge cases
Experience using AI coding tools such as Cursor, Copilot, or Claude as part of your daily engineering workflow

Experience with AI/LLM integrations, MCP tooling, agent systems, or retrieval-based architectures is highly preferred
Combination of startup and larger company experience
Experience operating systems handling millions of daily transactions, messages, or events
Strong familiarity with distributed systems, event-driven architectures, and cloud-native infrastructure
Comfortable operating in high-ownership, fast-paced environments with minimal bureaucracy

Responsibilities

Design and build scalable backend microservices primarily in Go powering a platform processing millions of daily communications and transactions
Own database architecture and write high-performance SQL queries with strong focus on schema design, indexing, optimization, and data integrity
Collaborate directly with product stakeholders to translate ambiguous business requirements into clear technical solutions and scalable systems
Build AI-enabled platform capabilities including LLM integrations, MCP tooling, agent workflows, and retrieval-based systems
Operate within a modern cloud-native infrastructure stack leveraging AWS, Kafka, Kubernetes, Docker, PostgreSQL, and Terraform
Use AI aggressively in your engineering workflow — the team are heavy users of Cursor, Claude, and Copilot to accelerate development velocity
Contribute to architectural decisions, scalability planning, observability, and engineering standards across the platform
