Shorebird | Mid-Senior Systems/Runtime (C++) Engineer| REMOTE (North America) | Full-time | $160-230k + equity + benefits | https://shorebird.dev

Flutter/Shorebird founder here. Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. We offer Flutter-related SAAS used by 1000s businesses globally, on track to profitability early 2026.

As part of our over-the-air updates “code push” product, we’ve built a custom compiler and runtime for the Dart language, primarily written by me (founder/CEO). Now that we have thousands of customers, I have many other responsibilities and need to bring on a fulltime engineer (you!) to take over primary responsibility for all of our C++ code (Dart & Flutter forks, custom runtime, compiler, etc.) and evolve it further than I could alone. Together, you and I will add obfuscation, improve our interpreter, possibly re-write method dispatch, etc. You don’t need to be a compiler/runtime expert. You do need to be capable of working on large open source projects, be comfortable with C++, want to work at a startup, work well independently (we’re remote) and want to learn and work on lots of different areas of code.

If you’ve contributed at least a little to WebKit, Godot, Firefox, or any other large open source project, are compiler/runtime curious, and want to work at a growing startup, you will likely find this role extremely rewarding.

We’re a small, senior team, making something people want. Tech: GCP, Cloudflare, React, Dart, C++, Rust. Shorebird operates almost entirely in the public over Discord. https://discord.gg/shorebird

Kernel Intelligence | Senior Backend Systems Engineer | Remote (US) | Python / FastAPI / Async / Distributed Systems

Kernel is building the data backbone for commercial real estate — converting messy CRE documents into structured, decision-ready data using ML and distributed systems. It’s a $20T+ market still trapped in PDFs and siloed tools, so the impact is immediate and real.

We’re an engineering-first company — our technical breakthroughs set the direction for what we can commercialize. Our team is small, senior, and high-trust. Every engineer owns production systems and directly shapes the platform’s capabilities.

You’ll design and own backend systems powering AI-driven pipelines: async FastAPI services, SQLAlchemy 2.x models, event-driven ingestion workflows (Pulsar/Kafka), multi-tenant auth (OIDC/JWT), Kubernetes deployments, and full observability.

Stack: Python 3.12+, FastAPI, AsyncIO, SQLAlchemy 2.x, Pulsar/Kafka, OIDC/JWT, Kubernetes, GitOps/Terraform, OpenTelemetry, Prometheus.

Comp: $150k–$200k + up to 3% equity
