SentiLink | https://www.sentilink.com/ | Engineering & Data Science | REMOTE, HYBRID, and ONSITE (UNITED STATES ONLY) | Full Time

Primarily hiring in the U.S. for more senior level roles.

We’re hiring across Engineering (Primarily Backend/Data Platform) and Data Science / ML roles. Hiring at Manager/Director level as well as Senior IC levels. We’re language-agnostic and hire for fundamentals.

Across the team you’ll see: • Python, Go, Rust, Scala • PostgreSQL, Snowflake • Kafka, Redis • Terraform, Kubernetes • ML: XGBoost, PyTorch, Feature stores, real-time scoring pipelines

If you love solving complex distributed systems challenges, building customer-facing ML products, or working on detection systems that must be both high-precision and low-latency, you’ll fit right in.

Roles are here: https://jobs.ashbyhq.com/sentilink?utm_source=hacker_news If you have questions, feel free to reach out directly at liz.woodfield at sentilink dot com.

At SentiLink, we stop identity fraud at scale. Our products protect banks, fintechs, marketplaces, and leading financial institutions from synthetic identity fraud, identity theft, and emerging threat. We analyze millions of applications while keeping real users moving fast.

We’ve seen tremendous traction and are growing extremely quickly. Our real-time APIs have helped verify hundreds of millions of identities, starting with financial services and rapidly expanding into new markets. SentiLink is backed by world-class investors including Craft Ventures, Andreessen Horowitz, NYCA, and Max Levchin.

SentiLink supports a variety of ways to work, ranging from fully remote to in-office. We operate as a digital-first company with strong collaboration across the U.S. and India. We maintain physical offices in Austin, San Francisco, New York City, Seattle, Los Angeles, and Chicago in the U.S. If you’re located near one of these offices, we would love for you to spend time in the office regularly. Some roles are hybrid or in-office by design.

We’re a small, high-impact team solving one of the most interesting and adversarial problems in fintech: how do you build systems that reliably determine whether a real human is on the other side of a financial transaction?

Footprint | Rust Engineers (Backend, Infrastructure, Security) | New York, San Francisco | ONSITE | VISA (case by case) | $180K-$260K + equity

We build Percy, an agent that runs financial-crimes investigations for banks and fintechs. It clears false positives, escalates real risk, and writes the case narrative and audit record a regulator will read. Under it sits four years of identity infrastructure: verification, an AWS Nitro Enclave-backed vault for PII, and the APIs our customers call directly. The backend is Rust.

We're hiring three Members of Technical Staff:

- Backend: the Rust APIs and services behind verification, vaulting, and the checks Percy runs. Production Rust is ideal; deep systems experience plus a real wish to learn it also works. Crypto or systems-security background counts for a lot.

- Infrastructure: own agent compute, isolation, deploys and observability across Rust services and long-running agents. Rust, Postgres/Aurora, AWS (ECS/Fargate), Pulumi/Terraform, Datadog, OpenTelemetry.

- Security: protect identity data we vault on behalf of regulated banks and fintechs, and prove to auditors every step was done right.

Small, senior team. Backed by QED, Index and BoxGroup. Customers include FDIC- and OCC-regulated banks plus Bilt, Nuvei and MoonPay.

Apply: https://jobs.ashbyhq.com/footprint. I'm the recruiter and will answer questions in this thread.

Paradromics | Embedded Software Engineer | Austin, TX or Oakland, CA | Onsite | Full-time

Paradromics is building a high bandwidth brain-machine interface for clinical use. The implant we built is restoring function to patients by streaming out neural data from specific brain regions in real time, which we convert to e.g. speech using machine learning. Check out our recent article in the NYT: https://archive.ph/C6CRb .

We're looking for help in further developing and hardening our embedded Linux components, which work in tandem with FPGAs and our custom ASICs to read out neural data. Some of the ongoing efforts are: HIL testing on real devices, integrating new sensor ASICs, maintaining our Yocto build system, exploratory work on prototypes, improving our clinical UX, and improving the core code that receives and massages data. The code is largely written in Rust with a little Typescript, (and bash, and bitbake recipes, etc).

You'll be expected to have experience constructing reliable and understandable software in Linux, and some level of experience in building and interacting with embedded hardware. Rust experience is ideal but not necessary. We're not looking for a specific number of YoE, but for motivated and hungry engineers who want to push the frontier of brain-machine interfaces.

To apply visit https://paradromicsinc.applytojob.com/apply/u5hXN4N9ID/Embed... or email your resume and a little about yourself to me, ehuber@paradromics.com . I'll be glad to hear from you!

Datamint | Rust Systems Engineer, Browser Security | Remote (Global) | Full-time | $120k–$170k + Equity | https://datamint.xyz

We build high-throughput crawling and structured data extraction infra designed for AI agents and LLM pipelines.

If you’ve built scrapers recently, you already know the state of the market:

- Traditional proxy providers (Bright Data, Oxylabs, Smartproxy, Proxybase) give you raw IPs or massive unparsed HTML blobs, leaving you to deal with DOM bloat, token waste, and brittle parsing pipelines.

- Modern tools like Firecrawl or Jina made clean Markdown extraction easy for hobby setups, but they often struggle when you throw heavy SPAs, high-concurrency jobs, or hardened anti-bot walls (Cloudflare Under-Attack / Turnstile, Kasada, DataDome) at them.

- Rolling your own Playwright / Puppeteer cluster works until target sites deploy new JA4/TLS fingerprints, and your data team ends up spending 30% of their sprints fixing broken crawlers instead of shipping product.

We're tackling this by combining a low-latency Rust fast-fetch engine (JA4/TLS and HTTP/2 frame emulation) with an isolated stealth browser fleet, zero-code schema validation (JSON Schema/Pydantic), and native Model Context Protocol (MCP) support.

Trade-offs / where we fit: If you just need to curl a few static Wikipedia pages, a 10-line Python script is better and cheaper. But if you need reliable, structured data out of bot-defended sites without babying headless browsers, that's what we do.

We're looking for:

1. Rust Systems Engineer: High-concurrency network I/O, Axum/Tokio, TLS/BoringSSL fingerprinting, proxy routing matrices, and low-latency data pipelines.

2. Browser Security Engineer: Deep familiarity with browser internals (Firefox/Chromium source), canvas/WebGL/audio fingerprint evasion, CDP/WebDriver stealth, and familarity with anti-bot defenses.

Our stack: Rust, Next.js 16/React 19, TypeScript, hardened Firefox/dwx_crawler, Linux/Xvfb, SQLite WAL/Postgres.

If interested, shoot an email to jobs@datamint.xyz (or founders@datamint.xyz) with your GitHub, a project you built or broke, and what you find interesting in this space. No formal cover letter needed.

Qualcomm | Canada | Full Time | Remote(Canada)| QEMU

My team is looking to hire a software developer to help us design and extend QEMU support [1] for the Hexagon DSP [2]. We're looking for candidates who have experience coding in C, C++ or Rust* and who aren't afraid of rolling up their sleeves and poring over disassembled code. This particular architecture is a bit more challenging than most, because it's a bit unique. It's a VLIW [3], so it's a great opportunity to learn about an interesting architecture. Millions of Hexagon DSPs are out there, most are found in DragonWing/Snapdragon/DragonFly SoCs for Laptops, Android phones, cars and more!

We collaborate a lot with Open Source communities like QEMU, LLVM [4], the Linux kernel [5], and more. I love being able to work on Open Source software at my day job.

You can contact me directly (email addr is in my HN user link). If you don't have experience with QEMU - don't worry! Most of us didn't have any experience with it until recently, too.

The rest of the team you'd work with lives mostly in Canada, EU, US.

* Rust experience may serve the role well but we don’t (yet) have any product software in Rust.

Cardog | Toronto, Ontario | ONSITE, HYBRID, REMOTE (role-dependent) | Full-time | https://cardog.app/careers

Cardog turns raw vehicle data into facts you can check: VIN decode, market price, recalls, and what the car's own modules report. Insurers, dealers, manufacturers and the public bodies that register vehicles all use it. We're a small team and every engineer owns a whole area.

Data - Data Platform Engineer (Remote). Own the datasets: government files, manufacturer filings, dealer listings, signals from the vehicle. Decide which source wins when two disagree, and be able to prove it. SQL first, entity resolution, tens of millions of rows. Postgres, TypeScript, Workers, R2. - VIN Decode Engineer (Remote). Own decode accuracy. Read manufacturer filings line by line, write the patterns, and test them against millions of real VINs. For people who are obsessive about correctness. TypeScript, Postgres.

Design - Design Engineer (Remote). Own the component library and the screens built on it. Dense data, and making uncertain or missing values look uncertain. You design in the browser and you merge it yourself. React, Next.js, Tailwind. - Founding Engineer, Dealer Platform (Toronto / Remote). First engineer on software for dealer groups. Time in stores, then ship it the same week. Strong Postgres, multi-tenant.

Business - Account Executive (Toronto / Remote). Enterprise and public-sector sales cycles measured in quarters. Run technical first calls alone and pull your own numbers in SQL. - Policy & Standards Lead (Ontario). Represent us in the consultations and standards bodies writing the rules for vehicle data. Closer to counsel than comms.

Field - Hardware Engineer, Vehicle Interface (Toronto). Own the diagnostic-port device: board, firmware, enclosure, from bench to a unit on a dealer lot. C or Rust, CAN at the frame level, UDS/ISO-TP against real cars. - Forward Deployed Engineer (Ontario). Take named accounts from the first meeting to a running system. TypeScript, SQL, and some time under dashboards.

Location: Boston, MA Remote: Yes (preferred) Willing to relocate: No Technologies: Python, TypeScript, Rust, SQL | pandas, polars, Arrow, DuckDB/DataFusion, Parquet, PostgreSQL | React, ag-grid, FastAPI, Django | MCP servers, LLM tool design, agent evals Email: paddy@paddymullen.com

I build data tools, from the dataframe backend to the browser.

I created and maintain Buckaroo (https://github.com/paddymul/buckaroo), an open source dataframe UI for Jupyter, marimo, and VSCode — summary stats and a histogram over every column, across pandas and polars. 683 stars. Scrolling millions of rows without eating the browser took a segment-merging row cache and parquet decoded client side.

Recently: Tallyman, a data science environment for coding agents. Named computations in a dependency DAG, results rendered live in a browser companion, every step keeping the prompt that made it. Demoed at PyData London 2026.

Before that: Flatfile, Attune, Tudor, and Bokeh/Wakari at Anaconda.

Looking for data infrastructure, developer tools, or agent tooling — where a hard backend problem has to surface as something a person can use.

Discord | Senior Software Engineer, Application Security | REMOTE (US West Coast) or San Francisco, CA | $196K-$245K base + equity

Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.

We are hiring a Senior Software Engineer to join the Application Security team. This is hands-on product engineering: building security features that protect user accounts, strengthening authentication and session security, and improving security-critical services. You will work directly with product teams to ship user-facing account security tools and address emerging threats.

Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.

Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and writing code across languages, experience shipping production software, and sound judgment on prioritizing real risk over checklist security. Experience with authentication, passkeys, MFA, or session management is especially relevant.

Location: Remote from the US West Coast. If you are in the Bay Area, our SF office is an option. Relocation to the Bay Area is not required.

Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.
