We're building the platform primitives that power https://copilot.com (Microsoft's ChatGPT). If you've shipped systems at scale—whether backend services, distributed infrastructure, ML platforms, or consumer AI products—we want to talk to you.
The work: design and build secure, performant platform services for AI at scale; collaborate with infrastructure, product, design, and research teams; ship high-quality code that reaches hundreds of millions of users; move fast in a design-driven environment.
You: solid fundamentals in systems thinking and software engineering; fluent in Python, C#, C++, Java, JavaScript, or similar; shipped real products or systems people use; can communicate across technical and non-technical teams.
Compensation: Competitive with other frontier AI companies, commensurate with experience. Relocation available.
We're actively hiring and will respond to qualified applicants. Check https://microsoft.ai/careers for current openings, or email maiplatformjobs@microsoft.com if something specific doesn't fit the bill. Apply directly if genuinely interested in building the future of AI.
New grads: If you've had 2+ MAG7+ internships (or adjacent large scale experience) AND a strong transcript from your university. Use [NEW GRAD] in the subject line.

Company: We're a small scientific software development company that develops custom scientific and engineering analysis applications in domains including: space situational awareness (monitoring the locations, health and status of on-orbit satellites), image simulation, high power microwave systems, modeling and simulation, laser systems modeling, AI/ML including physics-informed neural networks (PINN), human body thermoregulation, computer vision and image processing, high performance computing (HPC), computer aided design (CAD), and more. All exciting applications and no CRUD. We emphasize high quality code and lightweight processes that free software engineers to be productive.
Experience: Except for interns, we currently require a Bachelors degree in physics, engineering, math, computer science, or a related field. Masters or PhD is a plus. (Roughly 25% of our staff have PhDs.)
Technologies: Lots of C++23, Qt 6.9, CMake, git, OpenGL, CUDA, Boost, Jenkins. Windows and Linux, msvc/gcc/clang/clangcl. AI/ML and analysis projects use Python and C++. Web projects use Java and Typescript/React.

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome. We also recently acquired a fine-grained authorization company ( https://fusionauth.io/blog/fusionauth-acquires-permify ) and are going to be building in that area as well.
There are a lot of companies in the auth space, but we feel like we have something special:
* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* our CTO is the founder and still writes code
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration already
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.
Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.
Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.
AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.
We're looking to build our in-person team in NYC but also open to remote!
Apply: https://starbridge.ai/careers and mention HackerNews or email recruiting@starbridge.ai with your resume.
We offer a strong engineering culture and are looking for engineers to design and optimize high-performance trading systems that power our periodic auction matching infrastructure.
We build production systems in Rust and are seeking engineers with meaningful Rust, C++, Java, or Python experience, particularly from backend or systems-oriented environments.
Systems Engineer Systems programming role focused on low-latency, high-throughput distributed computing. Work across order and data workflows, auction execution, reliability, and performance optimization to ensure the platform is efficient, fault-tolerant, and capable of complex trade matching at scale.
We’re especially interested in engineers who: Have built backend or systems-level software | Care deeply about performance, concurrency, and correctness | Are motivated by real-time, performance-sensitive systems | Have experience with compilers, static analysis, or language tooling (a strong plus)
Software Engineer, Data Platform Build and evolve the infrastructure behind our analytics platform. The role sits between data engineering and backend development and focuses on high-volume, time-sensitive data pipelines and workflow systems that process terabytes of trading data and billions of rows daily.
We’re especially interested in engineers who: Have built internal data platforms or large-scale pipelines (Python/SQL; Rust a plus) | Have experience with workflow orchestration (Temporal, Airflow, Dagster, etc.) | Have worked with large datasets, columnar formats (Parquet/Arrow), and production data systems

Adobe is building a Real-Time Customer Data Platform (CDP) that operates at a scale most companies never see. We aren't just building another "enterprise app"; we are managing trillions of events and solving complex state problems in real-time.
If you find "distributed systems" a lifestyle rather than a buzzword, we want to talk. We are currently tackling challenges in high-throughput streaming, identity resolution at scale, and sub-millisecond data retrieval.
The Stack:
Core: Java, Scala, Spring Boot
Compute/Stream: Spark, Flink, K8s
Storage/Messaging: Kafka, FoundationDB, Aerospike, Cosmos DB, Delta Lake
Infrastructure: Multi-cloud (Azure/AWS), Docker, Vector DBs
What we’re looking for:
The "8+ Years" Profile: You’ve spent a decade breaking and fixing large-scale distributed systems.
Concurrency & Performance: You don’t just write code; you tune it. You understand the JVM, memory models, and how to squeeze performance out of every thread.
Architecture: Experience with Flink/Kafka/Spark isn't just about using the API—it's about knowing how they fail and how to keep them running under massive load.
The Logistics:
Locations: San Jose, New York, or San Francisco (Hybrid/Onsite).
Comp: $177,900 – $257,550 base + Equity + Adobe’s notoriously good benefits.
How to Apply: Email me directly at skatkar@adobe.com with "HN: [Your Name]" in the subject line.
