Mozilla / Thunderbird / Thunderbolt | Staff Product Engineer, Enterprise AI | REMOTE (US or Canada) | Full-Time | $185K–$220K USD / $155K–$185K CAD | https://grnh.se/viz7vum71us
We're building Thunderbolt (https://github.com/thunderbird/thunderbolt). We're an 8-person and growing team within the ~60-person company behind Thunderbird, the open-source email client used by 20M+ people.
Thunderbolt is an open-source, cross-platform AI product built on the principle that people and organizations should be in control of their data, infrastructure, and model choices. It's moving from early development into enterprise use cases, and we need someone to own features end to end — concept through launch, adoption, and iteration — not just close tickets.
You'd work full-stack on AI-powered chat, search, research, workflow automation, admin, and integrations. We're looking for 10+ years of engineering experience at Staff scope, hands-on AI product work (LLMs, RAG, agents, retrieval, model/provider abstraction), and comfort in ambiguity — architecture and enterprise requirements are still being defined. Bonus: self-hosted or regulated deployments, EU AI Act / GDPR / SOC 2 familiarity.
Must reside in and have work authorization for the US or Canada. No sponsorship. We read every cover letter - please make it authentic.

Tandem Health | Engineers, Designers, PMs | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building the AI-native operating system for clinics, so clinicians can focus on care rather than administration. We're building, launching and iterating quickly, and already support more than 10,000 care organisations across 14 European markets, including most of the NHS. We recently raised a $100M Series B to go further, faster.
It started with our AI medical scribe, which listens in to the patient-clinician encounter to generate medical records and saves clinicians 5-10 minutes per patient. Today our AI medical assistant supports clinicians before, during and after each visit, with medical coding and clinical decision support, three products certified as medical devices under EU MDR.
We're expanding our Stockholm team with exceptionally driven builders in a wide range of roles.

Location: Boston, MA Remote: Yes (preferred) Willing to relocate: No Technologies: Python, TypeScript, Rust, SQL | pandas, polars, Arrow, DuckDB/DataFusion, Parquet, PostgreSQL | React, ag-grid, FastAPI, Django | MCP servers, LLM tool design, agent evals Email: paddy@paddymullen.com
I build data tools, from the dataframe backend to the browser.
I created and maintain Buckaroo (https://github.com/paddymul/buckaroo), an open source dataframe UI for Jupyter, marimo, and VSCode — summary stats and a histogram over every column, across pandas and polars. 683 stars. Scrolling millions of rows without eating the browser took a segment-merging row cache and parquet decoded client side.
Recently: Tallyman, a data science environment for coding agents. Named computations in a dependency DAG, results rendered live in a browser companion, every step keeping the prompt that made it. Demoed at PyData London 2026.
Before that: Flatfile, Attune, Tudor, and Bokeh/Wakari at Anaconda.
Looking for data infrastructure, developer tools, or agent tooling — where a hard backend problem has to surface as something a person can use.
MeritFirst | Senior Software Engineer | Austin, TX (ONSITE) | Full-time
MeritFirst helps companies hire on demonstrated ability instead of pedigree. Candidates take realistic work-sample assessments, and employers get a signal they can trust more than a resume. We are backed by 8VC and Slow Ventures.
The hard part is building a signal good enough to influence real hiring decisions: fair to candidates, predictive for employers, explainable, and hard to game.
What you'll build:
- The product candidates use to prove what they can do
- The product employers use to find and hire them, and the scoring behind it
- The engineering bar the next hires will inherit, and helping us hire them
Stack: TypeScript, React, Next.js, Postgres.
We want people who have built and run real production software, debug from evidence, and do not need a fully specified roadmap. Early engineers, technical founders, and senior ICs do well here.
We use AI to move faster and to understand code better, but we do not blindly ship what it writes. You are expected to know and own every line you commit.
Start with the assessment: https://www.meritfirst.us/candidate/tests/40bfae94-dbf6-43fd...
It's my duty again to point out the popular request of including a 4DWW tag in the description to communicate community interest in the Four Day Work Week
