At Tessera Labs, we’re revolutionizing business process automation with cutting-edge AI technology. Backed by Foundation Capital and led by a world-class founding team, we’re building a high-impact engineering group to bring AI-powered automation to the enterprise world. Our multi-agent AI systems transform complex business workflows—eliminating inefficiencies, optimizing operations, and enabling seamless integrations across platforms like SAP, Salesforce, and Workday. We move fast, solve hard problems, and build at the bleeding edge of AI. About The Role We’re looking for a Backend Engineer (Mid-Level) who thrives in a fast-paced, high-ownership startup environment. You’ll help design, build, and maintain the backend systems that power Tessera’s AI automation platform — including scalable APIs, data pipelines, and integrations with enterprise systems. This role is hands-on and ideal for someone who enjoys building distributed systems, solving challenging backend problems, and contributing to architectural discussions in a collaborative, fast-moving team. Key Responsibilities Core Development Design, develop, and maintain RESTful APIs and backend services using Python (FastAPI, SQLAlchemy). Build reliable microservices that support data processing, automation, and AI system integrations. Implement and optimize database schemas, queries, and caching for performance and scalability. Contribute to data pipelines and synchronization services across enterprise integrations. AI & Systems Integration Connect backend services with AI model servers, vector databases, and automation workflows. Enable smooth data exchange between AI agents and enterprise systems like Salesforce, SAP, and Workday. Scalability & Reliability Identify and fix performance bottlenecks in backend code and databases. Implement caching, monitoring, and logging to ensure system reliability and observability. Collaborate with DevOps to deploy and maintain cloud-based services on AWS or GCP. Security & Quality Implement secure authentication and authorization (OAuth2, RBAC, SSO). Follow best practices in code quality, testing, and documentation. Participate in code reviews and contribute to improving backend architecture. Collaboration & Ownership Work closely with frontend, AI, and product teams to deliver new features. Take initiative in identifying improvements and building practical, scalable solutions. Balance speed and long-term scalability in a fast-moving environment. Qualifications 3–5 years of backend development experience with a focus on APIs, distributed systems, or cloud infrastructure. Proficient in Python, with experience using FastAPI, SQLAlchemy, or similar frameworks. Experience with PostgreSQL/MySQL and data modeling best practices. Familiarity with Redis, message queues (Kafka, RabbitMQ, Pub/Sub), and asynchronous processing. Experience with cloud storage solutions such as AWS S3, Google Cloud Storage, or Azure Blob Storage. Understanding of API authentication, security, and scalability principles. Strong debugging, testing, and performance optimization skills. Bonus Points Experience integrating AI/ML models into backend systems. Familiarity with event-driven architectures or workflow automation systems. Prior experience in startups or high-growth tech companies. No third party may recruit, solicit candidates, publish job opportunities, use Tessera Labs’ name or branding, or represent that they are acting on behalf of Tessera Labs without prior written authorization. Any such activity conducted without explicit written consent is strictly prohibited. Compensation Range: $200K - $250K
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.
