Hi there! At Veho, we don't sell software. We ship packages. Lots of them. We have all of the interesting problems that crop up when running twinned distributed systems in AWS and the real world. It's pretty great.
We're hiring staff-level folks (L4+) in NYC and Boston: Data Scientists, Data Engineers, Mobile Engineers, and Backend Engineers (typescript).
Personally, I'm hiring a Staff Data Engineer with the depth of experience to be a technical lead and mentor for the Data Platform team, while also shipping code. You will need to understand distributed data systems both intellectually and at an instinctive, emotional level. You should have Opinions about the wild boar book. You should probably also be comfortable writing and debugging English, SQL, and Python.
If that sounds like you, I really want you to apply for the Staff Data Engineer role on our career page. Our inbound applications are reviewed by humans.
With apologies that our first interaction requires this silliness: including one of the 7-digit numbers from the "ROS Calculator" on Veho's website in the appropriate box will heavily bias me towards believing you are a human being. That's more of an advantage than it may seem! It's worth the thirty seconds. It would also speed things along if you populate the "Location" field to confirm you are aware this is an in-office role.
At DeepL, we're building intelligent, trusted AI for language and beyond.

Here at Hearst we've been building out generative AI use cases and fluency across our portfolio of businesses spanning well known media brands to healthcare, transportation, and financial services. While we are an established corporation with multi-national presence, the mission and support behind our generative AI team more closely resembles a well-funded early stage startup as we engage in radical business transformation empowered by nascent technology.
The ideal candidate is one who has written code but now builds systems largely leveraging agentic development tools such as Claude Code (w/ Opus 4.5) & Codex (w/ GPT-5.2), and who sees the future of development as managing swarms of AI agents rather than cranking out code by hand.
Come join our team and help flesh out the future of business on a global sale while getting deep hands-on experience with the latest and greatest tech!

To be clear, this is a technical engineering role with hands-on coding and software dev that also includes aspects of product management, technical customer success and pre-sales solutions engineering mixed in. We’re language agnostic but strong Python and ML experience is a big plus.
2. Forward Deployed SRE: You will serve as the primary post-sales technical owner for our most strategic customers, ensuring smooth deployment, performance, and reliability of ML workloads in production. The role blends hands-on debugging, infrastructure expertise, AI model performance, and executive level customer facing ownership. We’re looking for deep Kubernetes and container orchestration experience along with a polished communication and executive level presence.
The Offer:
Compensation: Very competitive, we’re looking for folks with a breadth of experience
Equity: This is an opportunity to participate in the ownership of a fast-growing AI Infrastructure platform
Location: We are based out of San Francisco with offices in New York. We are also open to remote employees for these roles.

I’m hiring for some (IMHO) really fun product manager roles on Cloudflare’s Developer Platform (workers.cloudflare.com) - Workers Runtime - Set vision for our V8 isolate based runtime that lets people deploy JS, TS, Rust and Python to the globe in seconds with great dev ex. - Containers - Help build our new containers platform into the best place for both agent Sandboxes and stateless global apps. - AI Agents - Define what Agents on Cloudflare look like: from our AgentsSDK, to Sandboxes, to MCP Servers, “Code Mode” (see our blog) and more.
We’re a really technical group, and tend to like product managers that can straddle the line between engineer and PM. You should be able to set high-level vision, understand architectural constraints, and be technical enough to really deeply understand our users (developers).
email: <my-hn-username>@cloudflare.com - Please add “HackerNews” to the subject line.
Company: TextQL is working to drive the unit cost of a data-driven decision down to zero. We're building the agentic data lakehouse – finding trustworthy answers to hard questions from messy enterprise data without configuring schemas, moving data, or lengthy implementation roadmaps.
Roles:
* Platform: today, no one stakes their job on AI-generated queries. You'll build the system that changes that—giving agents the context to query enterprise data correctly, and the guardrails to prove it.
* Infrastructure: sandboxes are not enough for agents to work with enterprise data. You will develop reliable infrastructure for the first data platform designed to be operated agent-first – ETL pipelines, Trino clusters, and systems that let agents spin up infrastructure on their own.
Stack: Go, Haskell, TypeScript, DuckDB, Trino, PostgreSQL, Redis, Kubernetes, AWS
Perks: 21 days PTO, free lunch, 5% 401(k) matching, top-tier health insurance, visa sponsorship
How to Apply: email gabriel@textql.com with the most significant technical challenge you have solved, GitHub if you have one, and LinkedIn and/or resume (PDF).
We’re hiring an Enterprise AE to scale Parabola, a product used by finance and ops teams to automate messy, high-stakes workflows without needing engineers.
Parabola sits at the intersection of AI, automation, and real operational pain: unstructured data (PDFs, emails), brittle processes, constantly changing rules, and teams that can’t wait months for IT. Customers get to see live workflows in action immediately.
This is not a traditional enterprise sale... Deals are driven by automations, as they are built live in-app. Customers engage multiple times per week and see value instantly. Expansion is natural because the product is horizontal, the first team is never the last
We’re looking for someone who loves going deep on product and customer problems. You can work comfortably with operators and execs (CFO/COO) as well as with companies in the retail/ ecom/ CPG + freight/ logistics spaces. You care deeply about solving real problems. We're building the Enterprise motion, not just running a playbook.
Parabola had its biggest year ever in 2025. We’re consistently exceeding targets, and there is serious demand that is pulling us upmarket. You’d be working closely with our CRO, COO, CEO and GTM team to shape how Enterprise sales is done here. If you’re an experienced AE (5+ years in SaaS sales) who wants to sell something genuinely powerful with real customer impact, we’d love to talk.
