From venues and councils to private driveways, our platform makes it simple for drivers to find, book, and pay for parking—while empowering our operating partners to deliver exceptional parking experiences.
Join the JustPark Reporting team. You'll build, ship and maintain the data platform and reporting products behind our venue operations, used at venues like Mercedes Benz Stadium, The Greek Theatre and The O2 Arena. Following the 2024 merger of ParkHub and JustPark, we're scaling internationally, which means distributed systems, teams, and interesting problems at the intersection of payments, data and real time event operations. This is a hands-on engineering role where you'll own meaningful pieces of our platform from design through production, including keeping them healthy on live event days. We're an AI native engineering team: engineers use Claude Code, Copilot and Cursor as daily tools for code generation, review, debugging and documentation, and we build MCP integrations that connect our AI tools directly to Jira, Confluence, Slack and internal APIs so engineers stay in flow. You'll work closely with Product, QA, and our UK engineering and data teams to shape the data strategy of a fast growing international company.
Some of what you'll be doing: -Design, build and ship backend services and streaming data pipelines in Go that handle real world scale -Own data end to end: event schema and contract design, durable messaging patterns, and the read models and warehouse tables analytics is served from -Build financial data flows, including payment processor ingestion, fee reconciliation and ledger backed reporting -Ingest and reconcile third party data (partner files and payment processor APIs) with idempotent, replayable backfills -Develop and evolve API and GraphQL serving layers that power our internal and external products -Migrate existing reporting paths onto the new architecture

We're a global edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.
We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Onsite preferred, but remote candidates with a strong fit are welcome!
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
* The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services. * Apply: https://www.fastly.com/about/careers
We're building the VMware for GPUs. Most GPUs in the cloud sit idle a lot of the time because they're bolted to one machine over PCIe. We decouple them.
Our virtualization layer is a userspace shim, loaded through LD_PRELOAD, that intercepts CUDA calls and ships them over the network to a host with a physical GPU somewhere else in the data center. Workloads run unchanged. When a process goes idle, the GPU detaches and gets reassigned, and reattaches in tens of milliseconds when it's needed again. Think Ceph for GPUs: the GPU becomes a network resource a cluster-wide scheduler can pool and pack.
The hard part is making that fast. We're within ~10% of native on most AI workloads, and it lets us serve ~1.8x more users on the same fleet. We run it in production as our own GPU cloud and sell it to enterprises with underutilized fleets.
Team is from Citadel Securities, Aquatic, Old Mission, AWS, and Bain. Series A, $17.5M raised from Matrix and Y Combinator.

- Software Engineer, C++ Systems ($215K-$325K + meaningful equity). Low-level, latency-sensitive work on the virtualization layer. Quant dev / HFT background preferred: https://jobs.ashbyhq.com/thundercompute/2efae53b-817c-43e7-9...

Sidekick builds AI security software for enterprises. Our sensors observe AI behavior and use in situ. From those observations, our reasoning pipeline produces an application inventory and a risk picture, allowing us to provide real-time intervention and coaching right when it matters.
Compensation: base salary scaled to experience, meaningful early-stage equity, and 100% covered health insurance for you and your immediate family
We are a highly senior team. Most of us have been founders or on early founding teams, so we operate with high ownership. We expect you to have a real, current AI-assisted development practice. Our system spans several languages, and we expect you to use AI tools to quickly navigate unfamiliar parts of the codebase so you can comfortably own problems end-to-end across a broad stack.
We are hiring for three roles:
- Senior Software Engineer: You will work across our event-driven architecture. You'll write Go and Python backend services and touch endpoint-deployed browser and desktop components. You need to be comfortable developing in a multi-tenant, microservice-driven SaaS architecture and understand typical scale and security implications for such products.
- R&D Engineer: This is not an open-ended research function. You will take ambiguous feasibility questions tied to our roadmap and return defensible answers inside a week. You'll build handoff-ready prototypes, then shift into engineering mode to personally drive them through to production. You will also define operational envelopes and degradation boundaries, and rigorously deprecate infeasible ideas with documented rationale to avoid future re-litigation.
- Intelligence and Data Processing Engineer: This role is for someone who loves real browser and desktop forensics. You'll use dev tools and debuggers as your primary instruments. Expect to be reading minified code to find where state lives and analyzing network logs to understand undocumented APIs. You will figure out how AI products work and build the prototyping and automation to maintain our software inventory.
To apply: Send an email to eric+hn@sidekicklabs.com with the role in the subject. Include a PDF of your resume, a quick sentence or two about a tough technical problem you've solved recently, and links to your GitHub, personal site, and/or LinkedIn.
I'm Eric, VP of Technology, and I will personally read every email sent to the HN subaddress. You can view my background here: https://www.linkedin.com/in/three-two-one
