Job description

Maybe you're bored and need a new challenge. Or you've already changed how you write software with agentic coding tools, and you want to work somewhere that gets it. Or maybe you just want to work somewhere that trusts you to do great work without all the red tape.

Whatever the reason, we want you to know that LT is different. And not just air quotes "different," but more like "breathing easy for the first time in a long time" different.

We're looking to add a Senior Software Engineer to this nerd club of ours. If you're a seasoned engineer who knows your way around well-designed, event-driven systems, and agentic coding tools like Cursor and Claude are a real part of how you ship software, we'd love to chat.

Here's what you can expect as a Senior Software Engineer at LT:

• You'll work with a small, collaborative team (typically 3-5 people) to design, build, and deliver solutions that solve real business problems.

• You'll use agentic coding tools like Cursor and Claude every day to plan, write, refactor, and test code, while keeping a sharp eye on quality and design.

• You'll design and evolve systems using Domain-Driven Design, with clear bounded contexts, well-modeled aggregates, and meaningful domain events.

• You'll build and maintain event-driven architectures, including CQRS and event-sourced systems.

• You'll partner with product owners, clients, and fellow engineers to turn fuzzy requirements into clean, maintainable software.

• You'll mentor teammates, share what you've learned about good architecture and effective agentic workflows, and help raise the bar for the whole team.

What we're generally looking for:

• 5+ years of professional software engineering experience

• Proficiency with agentic coding tools like Cursor and Claude, including how to guide them well, review what they produce, and know when to take the wheel yourself

• Hands-on experience with Domain-Driven Design, including aggregates, domain events, and bounded contexts

• Experience building event-driven systems, with a working knowledge of CQRS and Event Sourcing

• Strong experience with Python and Django

• Experience with C# and .NET

• Curiosity, a problem-solving mindset, and a desire to keep learning
