Senior Software Engineer

About Kaleris

Kaleris is a private equity-backed software firm focused on supply chain optimization, headquartered in Atlanta, Georgia. We are a global leader in the supply chain execution market, accelerating the digital transformation of supply chains for industrial and finished goods shippers and carriers - combining best-in-class solutions for yard management, shipment visibility, and asset management across rail, truck, and multi-mode transportation.

Role Overview

We are looking for a Senior Software Engineer who thrives in a dual-track role: delivering on product roadmap commitments while serving as a technical escalation point for prioritized customer issues. You will bring deep engineering expertise to both planned feature development and reactive problem-solving, working closely with product, engineering, and customer success teams to keep our yard management and finished vehicles logistics solutions moving forward.

This is a high-impact role for someone who is as comfortable diving deep into an escalated customer issue as they are designing a well-architected feature.

Day-to-Day Responsibilities

Customer Issue Resolution

• Receive and own pre-triaged, escalated customer issues from the Customer Support team and drive them to resolution
• Debug and diagnose complex production and integration problems across the full stack
• Identify root causes and implement durable fixes - not just workarounds
• Communicate proactively with stakeholders on issue status, timelines, and resolution plans
• Document findings and contribute to internal knowledge bases to reduce repeat escalations

Roadmap Development

• Collaborate with teammates to formulate detailed designs, implement solutions from requirements, and estimate effort
• Participate actively in agile product development, including sprint planning, code reviews, and retrospectives
• Adhere to test-driven development practices and maintain high standards for code quality
• Support product deployments, configuration, and post-release validation

Experience Needed

• 5+ years of software development experience, with a track record of owning complex features end-to-end
• Strong Java proficiency - able to design, build, debug, and own Java-based services and features end-to-end
• Strong debugging and analytical skills - comfortable isolating issues across frontend, backend, and data layers
• Hands-on experience with HTML, CSS, JavaScript, and AJAX
• Solid experience with PostgreSQL - writing queries, analyzing execution plans, and resolving data issues
• Familiarity with queuing systems and API integrations (Redis/Resque, JSON-based systems, or similar)
• Demonstrated ability to balance competing priorities - planned roadmap work alongside resolving escalated issues
• Excellent verbal and written communication skills; English proficiency required
• Ability to work independently and with distributed, international remote teams
• Bachelor's degree in Computer Science or a related field, or equivalent practical experience

Nice to Have

• Experience with Ruby on Rails or comparable MVC web frameworks (Django, Laravel, or similar)
• C++ experience
• Familiarity with GPS, location-based services, or digital mapping technologies
• Experience with cloud infrastructure (AWS, GCP, or Azure) and deployment pipelines
• Background in supply chain, logistics, or transportation software
