BOSS-IQ | CTO Partner | REMOTE (worldwide) | Full-time | Istanbul-based company | https://boss-iq.com
BOSS-IQ is an AI strategic-planning product for owner-operators of small and medium businesses. The boss describes an idea that has been stuck for years; a research-and-question session returns an implementation-ready plan. In production since June, hand-onboarding our first paying customers since August, invitation-only.
I am looking for a partner rather than a first hire, and I need two things in one person. An experienced developer who has genuinely run software in production — deployments, incidents, on-call. And a black-belt prompter. I mean that as a level, not a flourish. The tell: if you watch other developers work in AI environments and feel real frustration — everyone prompts, most prompt badly — and you have quietly built your own standing rule files, your own context discipline, your own reusable prompt library, then you already know what I am describing. That is the rarer of the two skills, and the one I weight hardest.
Under the product, 60+ specialist agents run continuous extraction over each customer's documents and sessions into a persistent, per-company memory: every fact dated and traced to its source sentence, contradictions kept rather than overwritten — a discipline we call Total Capture. Patent-pending since July, in context engineering.
Stack: TypeScript throughout. A NestJS API plus a separate NestJS worker on Railway, Next.js 16 / React 19 on Vercel, Postgres with Prisma, Redis and BullMQ, Pinecone, S3-compatible storage. Agents are LangChain.js / LangGraph ReAct agents on Anthropic Claude across three model tiers, with OpenAI embeddings. Every prompt body and model config lives in one versioned master file synced to LangSmith, never hardcoded in TypeScript.
I am the founder, and not an engineer — thirty years a strategy consultant, first terminal at the end of 2022. A contract developer built the first ~20,000 lines between December and February. Since February I have been the only developer, and it is now about 264,000 lines of TypeScript. I wrote the prompts first, 18,500 lines across 79 agent files, and the code came after to serve them.
That was the environment, not me: 45 interconnected instruction files deploying sub-agents, around 300,000 words of standing rules, orchestrated by one always-on kernel that classifies each session, auto-attaches the rules matching the files being touched, and generates sub-agentic plans for the work.
Compensation is the honest startup shape: generous equity, austerity salary. No number here — it is set against what you currently earn, and that is a conversation rather than a billboard.
Full posting: https://boss-iq.com/cto-partner.html
Apply: https://boss-iq.com/apply-cto.html — one question at a time, ending by asking you to write the prompts you would use on day one, not code. I read every one myself.
Or write to me directly: ahmet@boss-iq.com
Founding Engineer with 15 years in IT. I build and ship business projects from scratch, backend, frontend, infrastructure, and I'm strong in AI (LLM integration, RAG, fine-tuning).
Happy to take full ownership of the technical side of a startup and move fast without a team behind me. Open to joining as a founding or technical co-founder, or first engineer.
Technologies: Python, FastAPI, TypeScript/Next.js, React, LLM/RAG (LangChain, LoRA/QLoRA fine-tuning on LLaMA/Mistral/Gemma), data engineering (DWH, ETL/ELT, Airflow, Spark), PostgreSQL/ClickHouse, AWS, Docker

Lucia | Director of Corp Dev · Product Marketing Associate · MLOps Engineer | Remote (NYC / SEA / global overlap) | $140K–$200K + meaningful equity
Distribution is one of the last durable moats left; models are commoditizing, but knowing how attention and demand actually move through a system still compounds. That's what we're building: a growth control plane that turns distribution into something you can model and act on with certainty. Get this right and the outcome isn't in question.
We're hiring across three roles:
Director, Corporate Development: own strategic partnerships, fundraising support, and M&A/inorganic growth. For someone who can operate at the intersection of deal-making and narrative, and help steer where this company goes next.
Product Marketing Associate: translate a technically deep product into sharp positioning and demand. For someone who can make causal modeling and world models land with real buyers. Experience with working with social media and influencers, Reddit strongly preferred. Data Science Background heavily preferred.
MLOps Engineer: own the infra behind our modeling; production pipelines and serving for causal graph inference, state space models, and world models (JEPA-I, JEPA-II style). Creating certainty in distribution, in production, not just in notebooks. Stack: Python, PyTorch, some Rust; GCP; Ray for distributed training.
Interview process: intro call, screen, virtual onsite, decision.

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

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.

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.

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.

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.
More info and application at https://www.springcraft.ai/careers/?role=manufacturing-engin...
