Software Engineer III

We're hiring a Software Engineer III to help build the next generation of developer tooling at Sinch. You'll work alongside a senior engineer on the CLIs, SDKs, web apps, and services that developers use to create, test, deploy, and operate software on Sinch. You'll focus on shipping new features. AI coding tools are part of the daily workflow here, and you'll get hands-on with them from day one. The team moves fast, so we're looking for someone who's already strong and wants to get a lot stronger.

Your Impact & Responsibilities

• Build features across our developer-facing CLI, SDKs, web applications, and backend services

• Ship improvements that make it faster and easier for developers to deploy and operate services on Sinch

• Use AI-assisted workflows in how you build, and help bring those capabilities into what we build

• Partner with the senior engineer and product peers to turn problem statements into shipped capabilities

• Contribute to reliability, observability, and developer experience as you go

• 3+ years of software engineering experience with full-stack exposure

• Strong TypeScript and modern web application experience

• Comfortable working across frontend and backend code, and willing to go deeper on either side as needed

• Active use of AI coding tools (Claude Code, Cursor, Copilot, or similar) as a core part of how you work

• Working knowledge of Kubernetes or container-based deployments

• Solid written and verbal communication

Who You Are

• You like working across the stack and want to keep broadening rather than specializing too early

• You like making developer workflows smoother and cutting friction for users and internal teams

• You're genuinely interested in AI coding tools and getting the most out of them

• You can take a defined problem and turn it into something that ships

• You'd rather ship something useful and improve it than wait for the perfect plan

• You're curious about how senior engineers approach hard problems and want to grow in that direction

• Experience with agent-based workflows or AI-assisted developer tools is a plus

• STAY HEALTHY: We offer comprehensive market competitive medical, dental, and vision plans. A variety of supplemental plans are also provided to meet your individual needs including access to telehealth for all participants.

• CARE FOR YOURSELF: Take advantage of our free virtual counselling resources through our global Employee Assistance Program. Your mental health is as important as your physical health.

• SECURE YOUR FUTURE: Plan for your future with our Roth and Pre-tax 401(k) options including an employer match for all participants.

• TAKE A BREAK: Enjoy a generous paid time off program. We value balance and understand that performance at work requires time to rest at home and/or rejuvenate on vacation.

• PUT FAMILY FIRST: We know that families can be built in a variety of ways; therefore, we offer paid parental leave and family planning support.

• WORK WHEREVER: Our flexible remote work offerings allow you to work wherever you are the most productive and successful. It is what you do, not where you work, that matters.

• MAKE AN IMPACT: Support betterment in your community and beyond by taking paid time off to support a volunteer program of your choice.
