Job description

Team Mission

The Configuration team is the backbone of Text. We store and manage the core data, settings, licenses, and properties that dictate how our applications behave for clients.

We build and maintain high-traffic services, public APIs (such as the Configuration API), and background processing mechanisms (Work-Queue) that teams across the entire company rely on. We also handle feature flags and analytics proxies (Amplitude). Our work directly impacts the core ecosystem of TextApp, ensuring that client settings and cross-domain tasks function flawlessly.

About the Role

We’re looking for a solid Backend Engineer (Go) with a strong sense of ownership to join the Configuration team. This is a role for a highly autonomous engineer - we need someone who has mastered the fundamentals, brings initiative, and doesn't just wait for step-by-step instructions.

In practice, your day-to-day will be a healthy mix of driving new feature development, maintaining existing systems, and refactoring legacy code. While Go is our primary language for new services, you will also navigate and maintain parts of our ecosystem built in Node.js as we continue our migration and refactoring efforts. We don't do isolated, heads-down coding for months - because our services power the core of Text, priorities can shift, and you will regularly handle ad-hoc requests and cross-team collaboration.

What you’ll do

• Develop, scale, and maintain backend services (Configuration API, TextApp services, Integration API) primarily in Go, while also supporting and evolving existing Node.js services.
• Design and optimize relational databases (MySQL/PostgreSQL) and caching layers (Redis).
• Take full ownership of your work: from picking up a ticket in the Kanban board to deploying and monitoring it in production.
• Handle cross-team requests and build configuration pools that other engineering teams will use in their applications.
• Participate in technical discussions and architectural decisions, advocating pragmatic solutions that balance trade-offs.
• Migrate and refactor legacy systems into modern, scalable solutions without disrupting existing production traffic.

Who you are

• Ownership mindset: you treat the systems you own as products, taking full responsibility for what you deploy to production.
• Independent executor: you have the initiative to take a problem, figure out the solution, and drive it to completion without needing someone to hold your hand.
• Pragmatic builder: you know how to balance building modern, top-tier tech with the reality of maintaining and improving legacy code.
• Collaborative communicator: you are comfortable talking directly to other teams across the company to understand their needs and solve their blockers.

You may be a great fit if you have

• 4+ years of backend engineering experience in product-focused environments.
• Strong, hands-on production experience with Go (Golang) as your main tool.
• Solid understanding of Node.js and a willingness to work with it for maintenance and migration purposes.
• Solid experience designing, querying, and optimizing relational databases (MySQL, PostgreSQL).
• Experience operating services in production under high traffic and scale.
• A proven track record of delivering features end-to-end independently.

Nice to have

• Experience with Infrastructure as Code, specifically Terraform.
• Familiarity with cloud infrastructure (GCP preferred).
• Experience working with Redis and background task runners or work-queue mechanisms.

Why you’ll love working with us

• High-impact visibility: your code powers the settings and configurations used by virtually every team and client at Text.
• Real engineering voice: you won't just be a "ticket taker." We make decisions based on technical trade-offs, and your arguments and input will actively shape our architecture.
• Blend of challenges: you get to work with modern, top-tier technologies while solving complex legacy migration puzzles.
• Clear success metrics: we measure success by your ability to independently ship real solutions to production, starting within your first 3 months.

If you enjoy taking full ownership of your code, working on high-traffic core systems, and solving problems that impact the whole company, we’d love to meet you.
