Estuary | US-Based / Remote | Full-time – https://estuary.dev/

Estuary is a VC-backed, post–Series A startup powering right-time data replication and transform — from sub-second CDC replication to terabyte-scale OLAP data flows.

We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.

We’re hiring for:

Head of Applications Engineering

Own strategy, people, delivery, and SLOs across our Applications stack (SaaS integrations, transformation UX, AI enablement).

Partner directly with the CTO to shape roadmap, sequencing, and engineering standards.

You’ll build and support a healthy engineering org, improve how we plan and deliver work, strengthen incident response, and step in to code when it helps the team move faster.

Great fit for someone who’s led multi-team groups, grown senior engineers, and shipped complex, data-heavy products.

Senior & Staff Backend Engineers (Integrations)

5+ years backend experience; Go required, Rust a plus. Own core systems powering real-time data pipelines. Build complex API/database integrations, improve connector frameworks, and tackle deep challenges in performance, reliability, and developer experience.

Source (https://source.network)| USA/Canada: REMOTE | Full-Time | https://careers.source.network

Our mission is to make it normal, not heroic, for edge AI, mobile apps, and critical software to run close to where data is born: on devices, in vehicles, in field hardware, not just in a distant GPU farm. We’re building the data and trust layer that lets developers ship systems that still behave correctly when links are flaky, latency is awful, and the cloud is optional instead of mandatory—instead of the usual “SQLite everywhere + ad-hoc sync” duct tape.

We’re growing fast and are looking to fill the following positions:

-Chief of Staff - https://source.network/careers/chief-of-staff

-Lead Edge AI Engineer - https://source.network/careers/lead-edge-ai-engineer

-Head of Developer Relations - https://source.network/careers/head-of-developer-relations-r...

-Lead Technical Writer & Documentation Engineer - https://source.network/careers/lead-technical-writer--docume...
