Senior Software Engineer
TXI is seeking a Senior Software Engineer who can see both the forest and the trees.
Building the right thing is as hard as building it right. Most products fail because they solve the wrong problem. We take a practical approach: embed integrated teams, understand the real need, then build something people actually use.
We build AI-powered workflows that solve real operational problems. Our primary focus is industrial products and services, logistics and distribution, and rail and fleet operations, with selective work in digital health, biopharma, and other industries where the challenges and mission align.
As a Senior Software Engineer, you have an opportunity to build modern, AI-enabled software that solves meaningful business challenges, partner directly with clients to shape products and technical strategy, and tackle complex engineering problems from concept through production—all while collaborating with a team that values craftsmanship, curiosity, and continuous learning.
Here’s what we expect from you
-
Expertly develop robust back-end and front-end code and have a solid understanding of different levels of automated testing to deliver reliable, well-tested features
-
Have a working knowledge of the infrastructure applications run on and can reason about how a feature deploys, scales, and operates in production
-
Drive the technical direction at the feature level, breaking down ambiguous problems, managing tasks effectively, and unblocking other engineers
-
Advocate for modular, maintainable architecture and a robust testing culture, strategically balancing test coverage, risk, and budget
-
Work fluently with AI-assisted coding and agentic development tools to move faster while holding their output to a quality bar
-
Establish healthy team norms around AI use, modeling critical evaluation of its output and communicating clearly about where it has shaped a deliverable
-
Continuously evaluate emerging technologies (including AI), capabilities, and limitations to identify new opportunities for TXI and their clients
-
Understand the client's business, build relationships with our clients, and guide strategic decisions to make them successful
-
Take ownership of the client relationship on straightforward projects, and build towards leading it on complex, politically nuanced accounts
-
Communicate professionally and empathetically, solicit and provide feedback, actively offer help, and make sure everyone is aligned
-
Work collaboratively on a cross-functional team of engineers, designers, and delivery managers
-
Develop proof-of-concept prototypes and demos that showcase technical possibilities and help clients envision transformative solutions
-
Take responsibility (even when no one asks) and learn from everyone, no matter what their title is
Our Tech Stack
-
Back-end: We primarily create applications in Python and Node.js (TypeScript),
-
Front-end: We generally use React, although some of our clients might use Vue.js.
-
Infrastructure: Our clients' infrastructure might be in either AWS, GCP or Azure, managed by Terraform or another IaC tool. We deploy containerized applications using Docker.
-
AI-assisted development: We expect senior engineers to work fluently with AI coding assistants and agentic tooling as part of their everyday workflow, and to help the engineering practice mature how it adopts these tools.
Don't hesitate to apply if you don't have specific experience with our tech stack. We have a preference for folks with experience in Python, Node.js, or React, but if you’re a strong developer with experience in related tools, we want to hear from you!
Who We Are
We’re a curious and humble group of people who are intentional about personal growth and supporting each other’s careers. We’re always looking for new skills, frameworks, and approaches to understand complex problems better and challenge our assumptions. And we’re constantly pushing ourselves to experiment,
