Constellation Finance | Multiple Engineering Roles | New York, NY | Hybrid | Full Time

At Constellation, we are building a future where technology is the lethal advantage in credit investing.

Credit documents govern everything from how much debt a company can incur, or pay in dividends, to what they can do with proceeds from selling assets. Hidden debt capacity, loosely drafted provisions, or ambiguous definitions can materially alter recovery, making precise covenant interpretation essential to investing outcomes.

Constellation makes it easy to read credit documents, calculate covenant capacity, and plan liability-management transactions, reducing the mechanical bottlenecks to analyzing credits and generating alpha.

Our team is comprised of subject matter experts who have spent a decade in credit (Goldman Sachs/Citadel), AI/ML researchers, and full-stack engineers who are dedicated to solving frontier problems in their application to the world's largest asset class.

We recently raised a $3.25mm round led by Haystack and Company Ventures. We are hiring for these roles: https://www.constellationfinance.ai/#/careers

You'll likely thrive here if you:

- Have 5+ years building and scaling backend systems - Are strong in Ruby on Rails and Javascript with solid SQL chops

- Enjoy owning complex features end-to-end, from design through production support

- Think in terms of edge cases, failure modes, and delivery guarantees

- Want to mentor other engineers and shape technical direction

- Care about building infrastructure that has direct impact on patient outcomes

This is a senior role with shared team lead responsibilities. Small, mission-driven team with meaningful ownership. Equitable pay regardless of location.

Fractional AI | Senior/Staff Software Engineer | SF, NY, NC, Dubai | Onsite

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. You’ll work on 3-4 different projects a year and play a central role on each one. No AI experience required: we are actively trying to be the best place in the world to learn applied AI.

I’m Frank, an engineer here. This is the first services-style company I’ve worked at, so for those of you in a similar boat, this is what I’ve really liked so far:

* The learning rate is super fast. 3-4 client projects a year, each with different tech stacks, products, industries, and architectures.

* Our projects are typically high priority and sponsored by prominent executives. The path here for projects to have real impact on usage or bottom line is much shorter.

* We’re “selling pickaxes during the gold rush”. When AI finds its next killer app, we’ll hopefully be the first to know about it.

We’re hiring SWEs onsite with offices in San Francisco, New York, Durham NC, and Dubai. Feel free to reach out to me directly (frank@fractional.ai) or take a look at the full job posting:

Tandem Health | Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.

Our first product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours.

We’re expanding our Stockholm team with exceptional builders in a wide range of roles.

PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Spotlight roles:

* Engineering Lead

* Product Software Engineering (Quantitative Modeling)

Ongoing hiring:

* Bayesian Software Engineering

* Program Synthesis Engineering

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

focal | Head of Technology & Applied AI | Remote/Onsite/Hybrid (US)

focal is an institutionally-backed, next-generation venture firm. Currently investing out of fund II (2025 vintage), we lead at the start, often pre-incorporation, with up to $1M. The next great venture firm won't just use AI. It will be AI-native from the ground up - seeing sooner, deciding faster, and building systems that compound across every founder, deal, and outcome. That's how a 5-person team beats a 50-person firm. We're building that firm. You'll own how it gets built.

This is a long-term, high-impact founding role with meaningful financial upside (carry in funds) and ownership over how the firm is built. You'll join as our 5th team member and partner closely with our GPs in a flat structure.

Your core responsibility: Build and own the AI-native operating system that becomes our structural edge.

Why this might be interesting to you: you get carry in our funds, full ownership over architecture and roadmap, and a problem space that's genuinely unsolved. Venture firms haven't been technically reimagined in decades.

Who you are: A founder-type. A builder: Highly technical, deeply curious, high-output, high-agency. You move from idea → architecture → shipped - fast. You want real ownership over process and outcome, not a seat at someone else's table. You've built things from scratch that worked, and you can point to them.

Comp: carry in our funds (your upside is tied to fund returns), competitive cash, 100% healthcare, 401(k), 6 weeks PTO, 3 months parental leave, budget for compute/tools.

We're not asking for a resume. Send us your LinkedIn (and X if you have it) along with your favorite thing that you've built and tell us why you're proud of it. GitHub, side projects, demos, whatever.

Chestnut | Product Engineers (Backend / Full-Stack) | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

Tetricus Labs | https://www.tetricuslabs.com/ | Full-Stack Engineer (Contractor) | Full-Time | Remote (APAC, UTC+5:30 to UTC+10:00) AND Remote (US)

We're a health tech startup building Personily, a psychiatric care platform that combines structured clinical measurement (PHQ-9, GAD-7, LPFS), passive sensing (sleep, steps, location), AI session transcription, and supervision tooling into a single platform for clinicians and patients.

We're looking for a full-stack engineer who can own features end-to-end across our stack:

- Backend: Python, FastAPI, PostgreSQL

- Frontend: React, Vite

- Infra: Kubernetes, GCP

You'll be building secure, high-performance APIs and clinician-facing interfaces, and taking features from concept through deployment. We're a small team, so you'll have real ownership and work closely with clinicians to shape how the product evolves.

Good fit if you: have strong fundamentals across the full stack, care about security and performance, and are comfortable diving deep into ambiguous technical problems.

We are hiring fully remotely in both APAC and the US, with a HQ in NYC.

Starbridge | Senior Engineers (Kotlin/Java/React/Typescript) | NYC or Remote | Full-time | starbridge.ai

Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.

Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

We're looking to build our in-person team in NYC but also open to remote!

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

  • Node.js

We’re a start-up company, we are building a local-AI camera OS that replaces cloud CCTV: SigmaStar cameras → RTSP/ONVIF → HDMI node → on-device AI (offline-first).

1. Hiring: OS / Device Lifecycle Engineer (Secure Boot / OTA / Identity) (Remote, UK/EU preferred)

We already run RTSP + inference. Now we need the person who owns several year device reality.

You will own (single layer ownership): Secure boot / trust chain (ROM → U-Boot → kernel → rootfs) OTA updates + rollback strategy (A/B, recovery modes) Device identity & lifecycle (provisioning, key rotation) Failure recovery (power loss, corrupted SD, watchdogs)

You must be able to answer directly: SD vs eMMC vs NVMe tradeoffs + corruption mitigation Brown-out behavior, thermal throttling, BSP maturity Camera ISP/NPU concurrency constraints + vendor SDK realities

2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)

We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.

You will own: Independent review of firmware/bring-up assumptions Validation of performance, thermals, power behavior, stability Reproducible test plans (what breaks, how to detect, how to recover) Documentation that prevents knowledge living in one head

If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.
