Valkyrie Aero | Software Engineer (Autonomy, Perception, Frontend) | REMOTE (US) | Contract | U.S. Citizens | https://valkyrieaero.com

Valkyrie Aero is a DoD prime contractor. We're building an airborne system for a manned counter-drone aircraft (that we operate) to enable a crew to find and engage Group 2-3 drones at low cost. Hiring contract software engineers for three roles:

- Software Engineer, Autonomy

- Software Engineer, Perception

- Software Engineer, Frontend (HMI)

We’re a small team (for now) so this isn’t your traditional defense program. Bureaucracy kept to the absolute minimum. If you can work across more than one of these domains that’s a huge plus.

I'm on the engineering team and read every application myself. I do not use AI to screen your applications and will read and reply to every single one; but please don’t send over walls of LLM generated text, I’d much rather be communicating with humans!

Apply: https://valkyrie-aero.breezy.hr/ and mention HN in your application.

PermitFlow (YC W22) | Staff, Fullstack & Frontend Software Engineers | New York, NY | ONSITE | Full-time | https://permitflow.com PermitFlow’s mission is to streamline and simplify construction permitting in the $1.6 trillion United States construction market. Our software reduces time to permit, supporting permitting end-to-end including permit research, application preparation, submission, and monitoring.

We recently raised a $54M Series B led by Accel with participation from Kleiner Perkins, Felicis, Altos Ventures, and YC.

Permitting is a challenging yet interesting problem; thousands of municipalities across the United States have their own processes and requirements - many which are continually updating. Software, AI, and LLMs provide an exciting opportunity for us to reason at scale and distill a nuanced and localized permitting process into a standard and streamlined experience for our customers.

We're looking for customer-obsessed, ambitious, and hard-working teammates who are excited about solving a real-world problem with technology at its helm.

Supero | Cloud / Platform Engineer | REMOTE (SF Bay Area, CA, US · Bengaluru, KA, India) | Full-time | https://www.supero.dev/careers/cloud-platform-engineer/

We generate full-stack apps and deploy them — a generated app becomes a live URL, on our infrastructure or in the customer's own AWS or GCP account. It's in production and it has more shell script in it than it should. You'd own it, and the mandate is to make it boring. Kubernetes, GCP and AWS deploy paths, CI/CD, observability, cost, tenant boundary.

No on-call rotation today — it's the founders and whoever last touched it. Building a real one is part of the job, not something you inherit alone.

4+ years production infra, Kubernetes past the tutorial, AWS and/or GCP at depth. The rest is on the page, including the open problems that don't flatter us. I'm a co-founder — ask me anything here.

Endless Access | Engineering Lead | Hybrid NYC | full time | 150k-250k

We're a mission-oriented org focused on bridging the global digital divide. Key to our strategy is our community game-making program: guiding learners to move from playing games to creating them. We're hiring a tech lead for our learner community platform.

Stack: Node.js, Nuxt/Vue, Apollo, GraphQL. 8+ years experience; open-source/community/edtech background desirable.

https://endlessaccess.bamboohr.com/careers/33

This is a true tech lead job: making calls about implementation, holding the standard, owning the shared delivery plan. You'll partner with a product lead on strategy, and with an engineering manager for roadmapping & delivery. You will also work hands-on in the codebase. We're a small team (about 40) and everyone is hands-on.

There's a unique org structure at play here: Endless is a multi-pronged organization, and two of them share the platform. So the role has one foot in each organization - the hiring entity is Endless Studios, and most of the engineers work at Endless Access. You'll collaborate with passionate, brilliant people on both sides of the house.

Harmonic | Technical Trainer | REMOTE (USA, East Coast based) | Full-time | 85k-105k USD

Key requirements: Up to 50% time can be mandatory travel for on-site in-person training sessions, very variable across the year. But no requirement to work in the office. Corollary to that - fluent or very good spoken English level is required. (PS: in actual practice it's about 1-2 work weeks every 2 months or so, irregularly)

Harmonic is a telecom hardware vendor. We are making hardware for the DOCSIS cable, PON fiber and mixed deployments.

Technical Trainer specialist is responsible for the presenting to the customer (MSOs) technical specialists, field technicians etc. the full overview of all possible product offerings by Harmonic, the full technical overview of every possible deployment (depending on the client's requirements) and full configuration for all hardware involved, including 3rd-party hardware. So no debugging and accessing code is needed, but if anything is customer facing, it must be explained.

As a brief example:

- Configuration for the DOCSIS core; - Configuration for the PON core; - Video streaming config; - Network L2/L3 switching configuration for multiple vendors;

The other half of the responsibilities is creating training materials, both text and graphics (designer is assisting our team too). Recording live narrated sessions too.

A familiarity with networking and/or DOCSIS is required. Both would be great.

Formal job listing: https://egmn.fa.us2.oraclecloud.com/hcmUI/CandidateExperienc...

Just apply at the link above, it's not a dead listing, we are actively looking for people now. Valid until I will comment otherwise. Reply under this comment for any clarifications.

Email: yuhruhgrape@gmail.com

I spent nine years as a process and R&D engineer in materials manufacturing, watching critical production data live and die in unversioned Excel files. I retrained as a software engineer to build the systems that should have existed. Currently full-stack at Downshift (part-time, TypeScript/NestJS/React Native) — part-time by design, so I'm free to move full-time. Available from October.

- Replaced a legacy Excel-based dataset with a Rails 8 + PostgreSQL application — schema design, data migration, and real-time dashboards replacing manual report assembly.

- Shipped Gemini-backed pipelines for two production problems: automated i18n across 3 locales, and structured extraction of medical data from uploaded images.

- Built auth from scratch, including OmniAuth for Google, GitHub, and LINE.

Crossref | Head of Infrastructure Services | REMOTE | Full-time | 120k USD or local equivalent

I'm the Director of Technology at Crossref and I'm looking for a Head of Infrastructure Services to join my team. This role will lead the strategy and evolution of Crossref's infrastructure ecosystem, own the infrastructure roadmap, and lead and develop our Infrastructure Services Team.

Crossref is a not-for-profit organisation that runs infrastructure that connects thousands of scholarly publishers and millions of research outputs, serving an increasingly diverse set of communities across scholarly publishing, research, funding, and beyond. Our system is a complex mix of legacy and modern components, some parts over 20 years old and tightly coupled, running on AWS with Terraform, Java, Clojure, Elasticsearch, and PostgreSQL. You'll play a key role in our efforts to modernise this system into a set of more loosely connected services.

We're looking for someone who's as comfortable getting into the weeds of cloud infrastructure as they are leading a team. If you've grown from a strong technical background into leadership, and enjoy using your technical expertise to help a team do its best work, this could be a great fit for you.

This role is fully remote, we are hiring globally, but we will need at least 2 hours overlap with European timezones.

Full job description and application form here: https://www.crossref.org/jobs/2026-09-01-head-of-infrastruct... We don't use AI as part of the recruitment process, all applications are screened by me. For any questions, feel free to message me here: https://www.linkedin.com/in/dtkaczyk/

Springcraft | Manufacturing Engineer | On-site in Palo Alto, CA | Full time

Springcraft is building the platform for physical AI.

Today, building robots and intelligent machines means navigating fragmented tools, incompatible hardware, and closed ecosystems. It takes too long, costs too much, and locks builders in. There is no default platform for physical AI. We're building it. Springcraft brings together purpose-built hardware, developer tools, and AI models into one open, integrated system so that builders can create machines that sense, understand, and act in the real world.

As the first manufacturing hire, you'll own how our hardware gets made, from first builds through volume production. This is a foundational, hands-on hire. You'll be on the bench and at the machines, partnering directly with our hardware engineers. You'll build the manufacturing function from zero and lead it as the company grows.

Our first product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. We're rapidly expanding our product suite now, with medical coding and clinical decision support out today, and more products on the way.

We’re expanding our Stockholm team with exceptionally driven builders in a wide range of roles. Especially on the lookout for Product Manager, Head of Product Design, and Director of Engineering.

Apex Dental Partners | Full-Stack Developer | Dallas, TX | REMOTE (US) or HYBRID | Full-time | apexdp.com

We're a Dental Support Organization running 65 practices across eight states. Dentistry doesn't sound like a technical job, but the platform behind it is: we've built our own operations system (Rails 8 + React, Electron, Go, and C#/.NET against OpenDental, all on AWS) and we're pushing hard on automation and AI to make the practices run better.

The team is small and developers own problems end-to-end. You'll figure out why a billing workflow breaks down, design the fix, ship it, and hear from the office manager who uses it the next week. Recent work includes an AI-first metrics layer that answers operational questions in chat, automated patient scheduling and communication, insurance verification scraping, and a live PMS integration across every practice. The domain is wide (clinical workflows, payroll, patient comms, revenue cycle) and there's a lot of novel work left once you learn the business. Big emphasis placed on being able to sit down with non-engineering team members and understand their workflows and build software to make it better.

Good fit if you want a stable company, a small team, broad latitude, and work that visibly matters to the people using it. We're actively building new features, not just maintaining what exists, so there's a healthy mix of greenfield work and improving a platform that's already in daily use by our nearly 1,000 employees.

Must reside in the US and be authorized to work in the US without sponsorship.
