Java Backend Developer Jobs

About Zencoder At Zencoder.ai , we build and orchestrate AI agents that ship real work - code, research, operations, and more. What started as developer tooling is becoming a platform where people and agents collaborate across knowledge work tasks. The Opportunity We’re looking for a passionate Senior Software Engineer to collaborate on building the next-generation AI coding platform. This is a rare opportunity to join an early-stage company founded by Andrew Filev (founder of a unicorn startup) — to help scale it into a thriving, world-changing business. Together, we’re shaping the future of software development — closing the gap between idea and reality, and influencing not only how code is written, but how progress happens across every field that depends on software. Key Responsibilities You’ll take ownership of designing and building key features. Our stack currently consists of TypeScript and Kotlin and you may be expected to work across all of them. This is not a “just code what’s assigned” role — we’re looking for people with a product mindset, who think deeply about users, bring ideas for product growth, and aren’t afraid to propose and launch new things. We value people who make things happen through their own enthusiasm, rather than waiting for managers to tell them what to do. Here, individual contributors hold the highest status — they are the driving force behind the company’s progress. You’ll work alongside top professionals in an environment that celebrates curiosity, creativity, and results. Essential Qualifications 10+ years of experience building complex, production-grade applications, including deep expertise in backend development in Java / Kotlin / TypeScript. Strong computer science foundation combined with a deep understanding of modern software architecture and design principles — and a proven record of applying them effectively in real-world, user-facing products. Product mindset — you think beyond code, care about the “why” behind the

About Supabase Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. Edge Functions are server-side TypeScript functions, distributed globally at the edge - close to your users. They power use cases such as webhook receivers, AI inferences, OG image generation and real-time bots (Slack, Discord, etc). Built on top of Supabase Edge Runtime : an open-source, Deno-based runtime written in Rust that runs JavaScript, TypeScript, and WASM services. We want developers to be able to build truly global applications by distributing both compute and data globally. Infrastructure concerns like regions, cold starts, CPU and memory provisioning should fade into the background so developers can focus on iterating on business logic. We are looking for experienced and passionate engineers to help us go further in this vision. What You’ll Own Evolving Supabase Edge Runtime - an Open-sourced Rust-based host that runs the Deno isolate, manages the main/user runtime split, and enforces per-request memory and CPU limits. Implementing monitoring, alerting, and OpenTelemetry tracing across the runtime, then using that visibility to drive optimizations that improve latency and reliability of the service. Working closely with the Deno and other open-source teams, contributing to upstream and relaying our users' requirements. Participating in an on-call rotation to keep Edge Functions healthy in production. Help manage and improve features like scheduled functions, background tasks, WebSockets streaming, ephemeral file storage, and custom routing. Integrating functions more tightly with the rest of the Supabase stack - Auth, Postgres, Storage, and Realtime. Expanding functions to support more use cases (AI inference, MCP servers, hosting simple websites, URL shorteners). Improving the DX

Role Purpose: At Jumio, the Software Engineer II (QA) will focus on ensuring the quality and performance of highly scalable web and backend applications. In this role, you will design and implement automated tests for web (Playwright/Selenium) and API-based solutions, leveraging your knowledge of Java or JavaScript. Collaborating closely with development and product teams, you will ensure Jumio's products meet the highest standards of quality and reliability. You’ll have an opportunity to learn and grow in a fast-paced environment while exploring new tools and methodologies. A problem-solving mindset, willingness to innovate, and attention to detail will make you successful in this role. T-Shaped Engineering Expectation: As part of Jumio’s engineering culture, you will adopt a T-shaped engineering approach. In addition to developing expertise in test automation and quality engineering, you will collaborate across the development lifecycle, including understanding software architecture, contributing to design discussions, and ensuring robust and scalable test solutions. Role Value: This role is critical to ensuring the reliability, scalability, and security of Jumio’s products. By building and maintaining automated testing frameworks, you will enable faster releases and higher confidence in the quality of our software. Example Responsibilities: Develop, maintain, and execute automated test scripts for web applications using Playwright, Selenium, or similar automation frameworks. Create and execute API test suites using tools such as Postman, REST Assured, or equivalent testing frameworks. Design and execute functional, regression, integration, and exploratory test cases based on business and technical requirements. Validate application functionality, backend services, APIs, and data flows across different environments. Identify, document, track, and verify defects, working closely with developers to ensure timely resolution. Execute automated test suites as part of C

About Supabase Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. About the Role We're looking for a SDK Engineer - JavaScript to join the SDK team and own a core part of how developers talk to Supabase from JavaScript and TypeScript. Our JS/TS SDKs are the front door to the platform: database queries, auth, storage, realtime subscriptions and edge functions, used by a very large number of developers and by most of the AI coding tools building on Supabase today. This is a library-authoring role, and the work happens in the open: public repos, public issue trackers, and API decisions whose consequences are permanent. The type system here is a design surface rather than a formality. If you get satisfaction from an inference that Just Works, from a migration guide that saves people an afternoon, and from an issue tracker that isn't a graveyard, you'll like it here. This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions. What You'll Be Responsible For Build and evolve our JavaScript/TypeScript SDKs. Start new things. Alongside the maintenance work, you're expected to find what's missing, make the case for it, and build it. Some of what we ship next doesn't exist yet, and nobody will hand you the list. Work in the open. These are public repos: you'll triage inbound issues, review and shepherd outside contributions, keep CI and release automation healthy, and hold a clear, kind line on scope. Own the type experience. Keep generated database types flowing correctly through the client APIs so autocomplete and inference stay correct in real codebases. Keep us honest across runtimes. Node, Deno, Bun, browsers, Cloudflare Workers, React Native/Expo, including dual ESM/CJS publishi
