Software Engineer with 3+ years of experience building scalable full-stack applications using React, Next.js, Java, Spring Boot, and AWS. Recently completed an M.S. in Computer Engineering from Virginia Tech. Experienced in building production systems, integrating LLMs into real-world applications, and developing end-to-end features from backend services to modern web frontends.

Looking for Full Stack Software Engineer, Backend Software Engineer, or AI Software Engineer roles at startups or product-focused companies where I can build impactful products, own features end-to-end, and solve challenging engineering problems at scale.

River (rivergtm.com) | NYC, on-site | Founding Engineer + Product Engineer | Full-time

River builds voice AI agents for B2B comapnies. Our agent talks with prospects in real time, answers hard questions, and demos the product by actually controlling a browser while it speaks. Every call runs on a sub-second loop: speech, a rendered avatar, several LLMs, and a live browser-use agent, in front of real buyers. $2M pre-seed backed by founders of Ramp, Kalshi, and JumpCloud.

Hiring two roles:

Founding Engineer (5+ yrs): own the live-call pipeline (real-time voice, avatar, browser streaming) and the infra behind it. Looking for strong backend/infra plus real-time experience (WebRTC, voice/video, websockets). Stack: TypeScript, Node, Next.js, Postgres, Redis, LiveKit.

Product Engineer, full-stack (1-3 yrs or exceptional projects): build the services behind live calls, LLM workflows, and the browser-use agent that runs demos. Backend-leaning, TypeScript.

Both on-site in NYC, working directly with the founders. Try the product yourself at rivergtm.com/start

Landjourney | Senior Full-Stack Engineer | Montreal, QC (hybrid, 2-3 days/week onsite) | Full-time | $160-170K CAD

We build lending software for agriculture: loan origination, automated document collection, white-labeled servicing portals, and a capital marketplace, sold to banks and credit unions. Seed stage, $4.5M raised, SOC 2 Type II.

Stack: Python/FastAPI, CockroachDB, Redis, Angular 22, Docker.

This is genuinely full-stack, and the front-end half is the part most candidates overstate, so we test it directly. Multi-step loan applications with cross-field validation, document collection interfaces, portals our lender clients rebrand as their own. Forms complex enough that state management is a real problem.

Our take-home is an agentic assignment. You pick one of three problems, use whatever AI tooling you like, and ship it running on Vercel. We do not care whether you wrote it unaided. We care whether you understood what came out. The full brief is public, so read it before applying and decide for yourself whether it is worth 2-3 hours: https://github.com/landjourney/agentic-assignment

After that, 45 minutes where you walk us through your code and add one requirement we did not tell you about in advance.

7+ years. French is an asset, not a requirement. No visa sponsorship.

Phonely | San Francisco, CA | Full Time | Onsite (5 days/week) | Senior Full Stack Engineer

https://phonely.ai

Phonely builds AI voice agents that automate phone calls for businesses. We’re a YC S24 company that raised our Series A in January and are looking for a senior full stack engineer to help build the future of voice AI.

Our stack includes TypeScript, Next.js, Vercel, Python, PostgreSQL, Kubernetes, AWS, Redis, and modern AI models.

We’re looking for engineers who enjoy owning features end-to-end, shipping quickly, and solving hard product and infrastructure problems in a small, high-performing team.

Experience with AI, voice, or distributed systems is a plus, but not required.

Reach out with your CV to recruiting@phonely.ai with “HN Hiring” as the subject.

Detections.ai | Full-Stack Engineer, Detection Platform | REMOTE (US & Canada) | Full-time

Detections.ai is building the platform for teams to create, test, organize, share, and improve detections.

We’re hiring a full-stack/product engineer with hands-on detection experience—writing or tuning detections, building SOC tooling, or integrating SIEM/EDR platforms.

You’ll own product features end to end across React interfaces, backend services, APIs, data models, search, integrations, and asynchronous workflows.

LLMs are a core product capability, not a bolt-on chatbot. Our assistant orchestrates domain tools and agents to analyze threat intelligence, search detection libraries, identify coverage gaps, create and translate detections, and ground recommendations in connected SIEM telemetry. We care about accuracy, evals, observability, hostile-input safety, and practitioner UX.

Stack: TypeScript, React, Next.js, NestJS, Python, AWS, OpenSearch, and Valkey/Redis.

Expected annual base salary: US$150,000–$225,000, or the Canadian-dollar equivalent, plus equity. The exact offer will depend on experience and role scope.

We’re looking for strong production web-app experience, end-to-end product ownership, and familiarity with some combination of Sigma, KQL, SPL, YARA, SIEM, EDR, or MITRE ATT&CK. We’re a small, experienced, remote team working directly with customers and security practitioners.

Apply: Email jobs@detections.ai with “HN Full-Stack Engineer” in the subject and a short note about your detection-engineering experience.

Ashby | YC 19 | REMOTE | Hiring Engineering Leaders | $200k–$275k Ashby is the all-in-one recruiting platform powering hiring at the world's most innovative companies. If you cmd+f "Ashby" you'll see that we're powering many of the job postings in this thread!

We’re looking to scale our engineering leadership team with technical leaders who want to raise the impact of a high-performing organization.

* Not Your Traditional "Jira-Manager": Our EMs are not classic delivery coordinators who shuffle meetings or build heavy processes. Instead, you will own people, hiring bar, technical judgment, and the health of our engineering systems.

* High-Autonomy Team: Because 80%+ of our engineering team is Senior–Staff+ level, our engineers already possess a high degree of ownership. Your focus is less on day-to-day task coordination and more on coaching independent owners, managing ambiguity, and raising team impact.

* Technically Credible Leaders: You will stay close enough to the work to challenge assumptions, review proposals, spot maintainability issues, and jump into the code to debug alongside engineers when needed.

* Organizational Advocates: Beyond your immediate team, you will act as an advocate owning the health and metrics of org-wide areas—ranging from CI/CD health and developer productivity to customer success collaboration and on-call sustainability.

* 100% Remote Async Culture: We maintain an even distribution of engineers across North America and Europe, optimizing for minimal process and maximum focus.

* Here's how we're thinking about AI at Ashby:https://www.ashbyhq.com/blog/engineering/ai-ashby-engineerin...

* Full transparency on engineering levels + comp:https://www.ashbyhq.com/blog/engineering/leveling-and-compen...

Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis. (While you won't always be shipping code, you are expected to hold a deep technical understanding of the system).

Shepherd (Series B) | ONSITE | San Francisco, CA & New York City, NY

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.

The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.

We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.

We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!

We’re hiring for 2 Senior and 1 Staff SWE in SF, and 2 Staff SWE in NYC. Engineers own projects end-to-end so full stack ability is expected.

Check out our open roles here: https://shepherdinsurance.com/careers

Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis

– If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.
