Here’s what we expect from you :

• You are a highly competent engineer who can lead multiple teams on significant accounts, with other team leaders executing specific lines of work under your guidance.
• Are a technical leader and able to efficiently execute code on projects, while also providing technical guidance to your team members.
• Can play a strategic role in shaping the organization, influencing technical direction, and driving major projects to success while positioning TXI at the forefront of industry advancements.
• Understand the client's business, build relationships with our clients, and guide strategic decisions to make them successful.
• Communicate professionally and empathetically, solicit and provide feedback, actively offer help, and make sure everyone is aligned.
• Partner with TXI’s Demand team to internalize prospective client needs, goals, and constraints; scoping complex product engagements based on business and user value.
• Serve as an experienced consultant; adeptly building lasting, influential relationships with executive-level clients that grow and expand over time.
• Take responsibility (even when no one asks).
• Learn from everyone, no matter what their title is.

Our Tech Stack :

• Back-end : we primarily create applications in Python and Node, although we have a small number of applications with other setups : Elixir and Phoenix, and Ruby on Rails.
• Front-end : For Javascript, we generally use React, although we have some apps that use Vue.js.
• Mobile : We support native iOS development in both Objective-C and Swift. These days, however, almost all of our apps are being built in React Native.
• Infrastructure : nearly all of our infrastructure is on AWS or GCP and managed by Terraform utilizing Docker containers in Kubernetes.
• Don't hesitate to apply if you don't have specific experience with our tech stack. We have a preference for folks with Python, Node.

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 deliver the most meaningful digital product experiences.

And we’re constantly pushing ourselves to experiment, explore, and challenge assumptions.

We bring that same passion for learning and growth to our clients, by digging into their organizations, reframing their problem statements, and spending time with their users.

This ensures that we’re pushing our clients forward while developing and delivering valuable products that matter.

We care about DEIB (diversity, equity, inclusion, and belonging). To deliver the best solutions, we need as many bright and diverse minds in the room as possible, and we need to be able to learn from them once they’re there.

Product, design, and engineering regularly collaborate.

We are intentional about supporting each individual's growth . "Challenge and support each other" is a core value of the company and we take that mission seriously.

That's why every employee has a personal learning & development budget and a bi-weekly conversation with their manager about their progress as well as why we created career grids to equitably promote each person's path at TXI.

We believe that wellness and a sustainable pace deliver the best outcomes. We commit to being dedicated partners to our clients for a sustainable 35 hours per week.

We don't require regular travel or client on-site time, though there will be occasional in-person client meetings to move work forward.
