Curiosity (https://curiosity.ai) | Forward Deployed Engineer, DevOps Architect | Toulouse, France | ONSITE | Full-time (CDI) | Visa support

Curiosity Studio builds internal apps and agents from a plain description, on a company's connected data and inside its permissions. It runs on premises or in a private cloud, with any LLM. We're bootstrapped, profitable and based in Munich. Our customers are large industrial and regulated companies, Airbus among them, and Studio has 30TB+ of data connected in production.

We are starting a team in Toulouse that works at customer sites, in French and English, along with the engineers who build Studio.

Forward Deployed Engineer: take a customer's problem from the first workshop to production. You decide with them what Studio should build, connect their systems, model the data as a graph, and oversee the C#/.NET connectors and services it needs. You also ship features and agents on top.

DevOps Architect: Own deployments in customer environments, from the first technical discussion to handover, on private clouds or data centers. Networking, IAM, Linux, Docker, monitoring, backups, upgrades, incidents. You also write code alongside the forward deployed engineers.

We're looking for hands-on builders who enjoy working directly with customers. Full-stack project experience preferred. Fluent French and English required.

Interviews: a 30 minute call, a technical conversation, then the founders.

Mozilla | Sr. Staff Software Engineer, Browser (New Products) | REMOTE (US or Canada) | Full-time

Mozilla's New Products group is a small team building new things on top of browser engine technology. We're hiring a hands-on, senior IC to run experiments inside browser engine internals and find out which ideas actually hold up.

What you'd do: design and build experiments in engine subsystems (DOM, layout, accessibility, JS runtime, networking), prototype features that let programs interact with web pages reliably, and measure everything. That means repeatable benchmarks, profiling overhead, and writing up the experiments that didn't work too. You'll use AI tools heavily, but you'll verify what they produce by testing and measuring it.

You likely have: deep experience in at least one browser subsystem, strong C++ or Rust, comfort in a very large codebase, a solid grasp of how the web platform behaves, and a real interest in AI agents and their tooling. Contributions to Gecko, Servo, Blink or WebKit are a big plus.

Postscript is an agentic retention marketing platform (SMS, RCS, Email) used by 20,000+ Shopify brands. We’re Series C and pacing toward profitability.

We’re rebuilding the platform from the ground up in Rust for the AI era, so the work mixes real scale problems (high-throughput messaging, deliverability, data pipelines) with a ton of 0 to 1 greenfield work where you shape the architecture.

Looking for senior engineers comfortable across the stack who are excited about Rust and like owning problems end to end. Fully remote team of ~250.

Mastra | Founding Sales (Founding AE) | US Remote | Full-time

Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed, https://github.com/mastra-ai/mastra

Why: Four months ago Mastra was a very popular open-source agent framework with very little monetization. Then we launched our platform, and now we're closing a couple of deals a week. Pipeline is growing faster than one person can work it, so this is our second dedicated sales hire. You start day 1 with a warm pipe: most leads are already using the open-source framework.

What you'd sell: Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs), Agent Builder (agents without code), and Concierge (embedded Mastra engineers working alongside customer teams). Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.

You have: Closed full-cycle deals in dev tools, OSS, infra, or AI. Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution. Founder or founder mentality. Comfort with a product that ships something new every week.

Apply: { https://jobs.ashbyhq.com/Mastra/d5fe8d36-843a-4f9b-9d65-779e... } We get back to everyone.

Kraus Hamdani Aerospace | Software Engineer | REMOTE (US) or ONSITE in Reno, NV

We build long-endurance autonomous aircraft and the software used to operate them.

Looking for a strong generalist software engineer. Most application work is TypeScript/web, with C/C++ and Rust elsewhere in the stack. You’ll work across frontend, backend, cloud, DevOps, and directly with flight test and hardware teams.

We care a lot about code quality, maintainability, and engineers who can take ambiguous problems and independently ship solid software. No sloppers.

U.S. defense/security eligibility required.
