SecureBio is a nonprofit working to protect the world from catastrophic pandemics. We operate the world’s largest metagenomic biosurveillance network, which performs daily sequencing of wastewater samples and nasal swabs to screen for emerging pathogens. Our computational team develops detection pipelines responsible for rapid processing of deep sequencing data in order to flag potential threats.
I'm the hiring manager for two roles:
- Senior infrastructure engineer, to own cloud infra, devops, CI/CD, AWS security, etc. https://securebio.org/careers/2026-cloud-infra-engineer/
- [Senior] software engineer focused on high performance data pipelines. https://securebio.org/careers/2026-software-engineer-pipelin...

3Play makes content accessible across disability and language. Our human-QA'd captioning, audio description, subtitling, and dubbing services are used by over 10,000 media, higher ed, creator, enterprise, and government customers. We’ve worked on really cool projects: recent examples including captioning the 2024 Paris Olympics and providing quality AI dubbing for high-profile YouTube creators.
I'm leading the Growth team, and we're working to build new, beautiful UI experiences on our long-loved services. Our stack is a Remix/Rails product and Astro/Sanity marketing site, both backed with modern design system foundation (what you might expect with Typescript, Tailwind, ShadCN, Tanstack, etc). I'm looking for a principal-level engineer with strong taste in front-end: someone who cares about UX and styling, takes accessibility and page weight seriously, builds strong validation / testing harnesses, and keeps a dependency tree sane instead of letting it metastasize.
The other part of this role is contributing to our agents and workflows. We've invested heavily here with the right mix of enthusiasm, guardrails, and budget. You'll have heavy influence over how it evolves: what we hand to agents vs. keep in human hands, how work gets specified and parallelized, how we keep the results beautiful, and where the security and review gates live. There’s a ton of opportunity to work with the latest AI tooling and determine best practices as the industry matures. We’re a small team happily working over 15 years with high impact, high autonomy, and low bureaucracy. Come join us! Apply at https://www.3playmedia.com/company/jobs-post/?gh_jid=7761973.... Mention HN when you apply!
Connie Health is a fast-growing Medicare brokerage on a mission to empower older Americans to make confident, worry-free Medicare plan decisions. We offer a tech-enabled Medicare navigation platform that combines AI-driven technology with local Medicare experts to help people select optimal healthcare plans and navigate their benefits. Backed by leading investors such as Khosla Ventures, we are building technology to transform the trillion dollar Medicare insurance industry, impacting the lives of 67 million people in the US.
We are looking for a Senior Analytics Engineer to own our data transformation layer end-to-end. You will build the clean, well-modeled, documented datasets that the entire company relies on, spanning board-level book-of-business reporting (policy count, retention, effectuation, commissions), stakeholder self-service through Looker, and AI-driven exploration through tools like Claude. This is a high-leverage senior IC role: the quality of our analytics, forecasts, and operating decisions all depend on the foundation you build. You'll partner directly with Engineering, Finance, and Operations to fix data quality at the source, not downstream.
Tech stack: SQL, dbt, Redshift, Postgres, Looker (+ LookML), Fivetran, Airflow, Salesforce
We're looking for 5+ years in analytics/data engineering, deep hands-on dbt experience, strong SQL, and a track record of turning messy datasets into a trusted single source of truth. Bonus points for retention/lifecycle modeling, Looker administration, prepping datasets for AI consumption, or Medicare/insurance experience.

Last week, the FAA awarded us a 12-year, $875M contract to build FMDS and SMART - the flow-management and airspace optimization systems that will become the technological backbone of the FAA's Air Traffic Control. What we ship in the next two years will define how this country moves through the sky for the next fifty.
At the core is one of the largest real-time optimization problems in the world: how do you safely sequence ~40,000 flights/day while routing around weather, military airspace, equipment outages, and constant real-world churn? The system has to be right every time, and reliable at scale.
