SeniorBackend Engineer Communications AI Infrastructure Bengaluru, India | Full-Time | Engineering Reimagine How The World Communicates with AI We're reimagining how people communicate using AI; from smart assistants that schedule meetings and transcribe conversations to systems that understand voice, video and text in real time. Such applications need a foundational distributed infrastructure that powers millions of concurrent calls and processing volumes of data. Were looking for a backend engineer who can design and scale these core systems. Join our Bengaluru engineering team to build the backbone of AI driven communication. What Youll Do Build ultra-reliable, low-latency backends for real-time calls, messaging, and media workflows at scale.Design high-throughput event pipelines that power real-time signaling, analytics and AI feature processing with minimal lag.Design distributed coordination and routing systems that maintain consistency and performance across regions.Develop scalable platform primitives like RESTful APIs, identity, sessioning, rate limits and storage that serve as foundations for AI-powered applications.Create end-to-end observability that keep a multi-region UCaaS platform predictable under heavy load What You Bring 913 years of hands-on backend engineering building and operating large-scale distributed systems, with a deep understanding of consistency, partitioning, replication and high availability fundamentals.Good system design expertise, with the ability to architect fault-tolerant, horizontally scalable services.Expert proficiency in at least one modern backend language (e.g., Java, Kotlin, Python, Go), with the ability to write high-performance code and lead technical reviews across complex systems.Experience designing and scaling high-throughput or low-latency services, including API design, concurrency models, resource management and performance tuning across distributed workloads.Proven ability to build event-driven or asynchronous architectures using distributed messaging or streaming systems(e.g., Kafka, Kinesis, Pulsar, RabbitMQ).Hands-on performance and observability skills, including profiling, eliminating bottlenecks, optimizing tail latency and implementing robust metrics, tracing, and logging for distributed systems Nice to Have Understanding of networking fundamentals and cross-region or multi-DC architectures, including latency tradeoffs and data movement considerations Why You'll Love Working With Us Youll build things that scale globally Youll work on real problems: scale, efficiency, optimization. Youll be part of a global team collaborating with top engineers Accelerated career growth due to highly visible projects. Hybrid work from our Bengaluru office + flexible hours. Full medical insurance for you and your family. Competitive compensation + performance bonuses If you are passionate about building production-ready scalable systems that redefine human connection, this is your moment. Apply now. .
Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
