Golang (Go) Developer

Job Title: Principal Go Developer Location: Denver, CO Long term Contract Profiles should be 12+ years Mandatory Skills GO/Golang, MySQL/Oracle/PostgreSQL, AL/ML, AWSOptional Skills Java, Python, Kubernetes, Docker Job DescriptionPrincipal GO DeveloperWe are seeking a Senior Engineer to own and evolve a production-critical payment platform responsible for high-volume financial transactions. This role is focused on stability, correctness, and long-term system stewardship, not greenfield development.In addition to strong programming expertise, this role requires experience embedding AI/ML capabilities into enterprise systems and SDLC processes, supporting AI-driven transformation initiatives such as intelligent automation, anomaly detection, and data-driven decisioning within transactional platforms.The ideal candidate has deep experience operating Tier 1 systems where reliability, data integrity, and performance are non-negotiable. They demonstrate strong engineering judgment, maintain a disciplined and low-complexity approach to design, and are capable of driving meaningful improvements independently within an existing distributed system.This role requires a hands-on engineer who can lead through execution, make sound technical decisions under real-world constraints, and contribute to the long-term evolution of a high-value platform, including selective adoption of AI/ML capabilities where they improve system outcomes without compromising stability.Required Qualifications* 12 plus years of experience in software engineering, demonstrated experience building and operating production-critical backend systems with meaningful business or revenue impact.* Strong hands-on experience with Go/Golang or Java based technologies in real-world production environments.* Experience integrating AI/ML solutions into enterprise systems, including deploying, consuming, or operationalizing ML models.* Understanding of AI/ML concepts such as supervised/unsupervised learning, model evaluation, inference pipelines, and data quality considerations.* Experience applying AI/ML within SDLC processes (e.g., testing, monitoring, observability, or developer productivity tooling).* Deep experience with relational databases (e.g., MySQL, PostgreSQL, Oracle), including schema design, transactional modeling, and performance optimization.* Strong understanding of transactional systems, including data integrity, idempotency, reconciliation, auditability, and failure handling.* Proven ability to make pragmatic, low-complexity design decisions in distributed systems.* Experience working within and improving existing systems with real-world constraints, rather than primarily greenfield environments.* Ability to independently identify problems, define solutions, and drive execution to completion.* Strong communication skills, including the ability to work effectively with both technical and non-technical stakeholders.
