Software Developer II

At Wi‑Tronix, we’re transforming rail safety, performance, and operations through real-time insights and intelligent digital products. We’re looking for a Software Developer II who is passionate about writing clean, tested backend code, enabling empowered product teams, and delivering outcomes that matter, not just shipping features.

As a Developer II, you’ll work within Wi‑Tronix’s Product Operating Model, building the server-side logic, data pipelines, and APIs that power our railroad intelligence platform. You’ll collaborate closely with Product and Design in a cross-functional team built around real customer problems and measurable outcomes.

This role is perfect for a developer who cares about code quality, is genuinely curious about AI, and wants a mission they can believe in.

CORE FUNCTIONS

Build and Deliver

•     Design, develop, and ship scalable C#/.NET backend solutions that fulfill clearly defined product outcomes

•     Write well-tested code using unit, integration, and functional testing frameworks. Quality is built in, not bolted on.

•     Contribute to REST API design and microservice development in a modern .NET environment

•     Build and maintain SQL schemas, stored procedures, and data pipelines that support real-time rail operations

•     Validate completed work with Product Managers and participate in releases to confirm outcomes are met

Collaborate and Discover

•     Participate in requirements reviews and design discussions with Product Management, Product Delivery, and IT colleagues

•     Contribute to the team’s discovery work by surfacing technical feasibility concerns early and helping shape solutions

•     Share ideas and provide input during design sessions; help create artifacts that move the team forward

•     Perform root cause analysis on escalations and communicate bugs and findings clearly to the Associate Product Manager

Deliver with Quality

•     Follow Wi‑Tronix development standards and continuous delivery practices: small, low risk releases that can be validated and iterated quickly

•     Ensure documentation stays current as code evolves

•     Participate in SAFe ceremonies as a contributing team member

•     Stay close to release telemetry and dashboards, treating defects as feedback that improves the product

Grow and Contribute

•     Collaborate with your manager on career development and growing your professional competencies

•     Stay current with emerging tools and technologies, particularly AI assisted development

•     Participate in training, knowledge sharing, and continuous improvement across the team

POSITION QUALIFICATIONS

•     B.S. in Computer Science, Computer Engineering, Electrical Engineering, or a related field, or 5+ years of equivalent professional experience

•     3+ years of professional software development experience (or an M.S. in a related field, or 1+ year of relevant internal experience)

•     Proficiency in C# with .NET Framework, .NET Core, or .NET 6+

•     SQL skills including complex queries, stored procedures, and schema design

•     Demonstrable experience using AI-assisted development tools to translate specifications into working, testable code

•     Solid Git workflow: branching strategies, pull requests, and code review

•     Comfort in Visual Studio or a comparable IDE

•     Ability to operate successfully in a lean, fast paced organization

•     Technology enthusiast demonstrated through work experience, hobbies, and/or education

•     Agile mindset: the ability to work iteratively, support rapid prototyping, and contribute to effective feedback loops

Nice to Have:

•     REST API design and microservices in a containerized environment

•     Exposure to C++ (select services; deep expertise not required)

•     Unit testing frameworks such as xUnit, NUnit, or MSTest

•     MS SQL performance tuning and optimization

•     Experience with AWS or other cloud platforms

•     Jira or TFS work item tracking

•     SAFe or other Agile certifications

•     Background in transportation, IoT, or safety critical systems

WORK ENVIRONMENT

•     Hybrid schedule: Tuesday, Wednesday, and Thursday are designated in-office days at our corporate office in Bolingbrook, IL. Monday and Friday may be worked remotely or in the office; however, employees must be available to come on‑site for all days as business needs require. 

•     Occasional ability to board a locomotive for field observations may be required

•     This role requires the ability to begin work within approximately 1 to 2 weeks of offer acceptance

CAREER PATHWAYS

Your growth matters. This role can lead to:

•     Developer III → Software Development Manager or Principal Engineer

•     Or broaden into: DevOps, Software Architecture, or AI adjacent engineering roles
