Point One Navigation

<div><h1 class="jobSectionHeader">Staff Network Backend Engineer</h1>
Location: San Francisco, CA / San Diego, CA &ndash; In Office 3 Days/Week<h2 class="jobSectionHeader">
About Point One Navigation</h2>
Point One Navigation is on a mission to bridge the digital and physical worlds through precision location. Our RTK Corrections Network and Positioning Engine deliver centimeter-level accuracy and high-confidence positioning for vehicles, robots, drones, and devices across industries. We're API-first, developer-focused, and pushing the boundaries of autonomy and automation.<h2 class="jobSectionHeader">
Role Outcome</h2>
Staff Network Backend Engineers own the design, implementation, and reliability of the backend services and APIs that power Point One's RTK Correction Network - from correction-data ingestion and distribution to the customer-facing APIs that deliver positioning at scale.
This is an ownership-first role: you will design and build distributed systems that serve real-time corrections to hundreds of thousands of devices in the field, with the latency, availability, and the correctness that mission-critical positioning demands.
The RTK Corrections Network is the backbone connecting our reference stations to every device that depends on us. This team is responsible for keeping it fast, reliable, and scalable: designing services that handle growing traffic, responding to evolving customer needs, and ensuring the network stays observable, tested, and production-ready as it grows.<h2 class="jobSectionHeader">

Scale the RTK Corrections Network<ul><li>
Own the ingestion, processing, and distribution of GNSS correction data from reference stations to devices in the field.</li><li>
Design streaming and connectivity paths (e.g., NTRIP and similar protocols) that deliver corrections reliably and at low latency.</li><li>
Expand network capacity and coverage as new regions, stations, and customers come online.</li></ul>
Build Reliable Distributed Systems<ul><li>
Design for high availability, graceful degradation, and recovery under partial failure.</li><li>

Our Cultural Foundation</h2>
At Point One, our cultural and operating design is built around one guiding principle: we must move with extreme speed and efficiency of effort to stay in a leadership position.
This environment gives people a high level of autonomy and the ability to make a real impact. It also challenges every team member to grow &mdash; both professionally and personally. Because we focus on promoting from within rather than relying on external hiring, the opportunities for advancement are tremendous for those who seek them.
That said, growth only comes from delivering in the present. What matters most is the job to be done today, not the job you want tomorrow. When we all focus on today&rsquo;s outcomes with excellence, the path to greater responsibility and growth naturally follows.
We think about our culture in two dimensions:<h2 class="jobSectionHeader">
How We Show Up Every Day</h2>
These are the behaviors we expect every team member to bring to work &mdash; the foundation of being a consummate, high-output teammate:<ul><li>
Trust / Assume Best Intent &mdash; Trust allows us to move fast. When we start from trust, we spend no time second-guessing or looking for ulterior motives and thus focus all our energy on acting.</li><li> 
High Output, Action Oriented &mdash; Our default posture is &ldquo;yes.&rdquo; We bias toward action and deliver results quickly, knowing that speed and efficiency compound into impact as we unblock others around us.</li><li> 
Divine Discontent &mdash; We&rsquo;re never satisfied with the status quo and are self-motivated to improve ourselves, our work, and our company. We actively seek feedback in real-time to shorten improvement cycles.</li><li> 
No Ego, One Team &mdash; Collaboration without ego creates leverage. When we win as one team, we eliminate friction and move faster together.</li><li> 
Self Accountability &mdash; Taking ownership is the straightest line to learning, self-improvement, and correcting our course of action. And blaming others around us is a fast path to destroying trust.</li></ul><h2 class="jobSectionHeader">
Operating Principles</h2>
These are the systems and norms that amplify speed and efficiency at the company level:<ul><li>
Edge Innovation &mdash; We bias toward action over approval. Experiment, decide, and move &mdash; failure is just a step toward faster learning.</li><li> 
No Hierarchies &mdash; We practice self-prioritization and go direct to the source. Flattening layers reduces drag and maximizes autonomy.</li><li> 
Customer Experience First &mdash; We optimize for the end-to-end customer outcome, not functional or departmental efficiency. This focus cuts waste, aligns priorities, and ensures we spend effort where it matters most.</li></ul>
If this role sounds like a fit, we&rsquo;d love to hear from you. Apply below and join us in shaping the future of precise location.

Lumafield

<div>
 
 
 About Lumafield:&nbsp;
 
 
 
 
 
 
 Lumafield was founded in 2019 to upgrade manufacturing.
 
 
 
 
 
 We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.
 
 
 
 
 
 Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.
 
 
 
 
 
 We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We&rsquo;re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.
 
 
 
 
 
 Lumafield is headquartered in Cambridge, MA, and has an office in San Francisco, CA.
 
 
 
 
 
 
 About the role:&nbsp;
 
 
 
 
 &nbsp;
 
 
 
 On Lumafield&rsquo;s Backend team, you work on the core of our cloud platform from REST APIs through to massively parallelized data processing pipelines operating on our X-Ray and CT image data. We leverage Python in order to move quickly but ensure that we&rsquo;re getting the most out of the language through usage of powerful frameworks and parallelism concepts. Our backend team also owns their code all the way through deployment; you&rsquo;ll work to build your code into Docker containers and deploy them to our different environments including cloud Kubernetes clusters and on-premises servers.
 
 
 
 &nbsp;
 
 
 
 
 
 
 What you'll do:
 
 <ul>
 
 <li>
 
 
 Use Python, Django and Django Rest Framework (DRF) to implement cloud backend APIs
 
 
 </li>
 
 <li>
