TalkJS lets developers build a perfect chat feature in just a few minutes. We power communication in online marketplaces, community sites, multiplayer apps, trading platforms and so on. We're product driven and we care tremendously about quality. TalkJS touches millions of people and is growing quickly. We want to be the tool that every developer thinks of for building communication features, a bit like what Stripe is for payments. 80% of the company is product people, founders are a designer and a programmer. Our strategy is to give great engineers a maximum amount of freedom, so they can ship fantastic SDKs, APIs and features. This means a lot of responsibility, a lot of agency, a sane work/life balance, no meetings, no red tape. We're growing, profitable, and not dependent on venture funding.

We do enterprise document ingestion — capture a document once into a canonical field registry, then project it to any schema, no re-extraction. Stack: AWS, Docker, Railway. We've never had a dedicated reliability owner and it's starting to show. You'd be the first: SLOs and an error-budget policy that actually gets honoured, observability worth paging on, post-mortems that change the architecture, deploys nobody dreads. Target is 99.9%. Compliance is real here (GDPR, ISO 27001/42001, HIPAA), so reliability and audit work overlap. Haven't used Railway? Fine, we'll onboard you. We ship with Claude Code day to day — if that's interesting rather than irritating, good. Process: founder chat (bring a Sev1 you've owned), a paid day building with us on something real, team fit, references.

Talroo is a programmatic job-advertising platform, focusing on hourly blue-collar workers. Talroo operates a few job boards and a search API used by hundreds of other job boards. We are a privately owned company, and the founder is a talented engineer entrepreneur who wrote most of the code and scaled his company to $200M without ever taking a loan or VC money.

We enable any scientist to access AI-powered drug discovery. Thousands of scientists from large pharma companies, top biotechs, and academic institutions use Tamarind to design protein drugs, improve industrial enzymes, and create cutting edge molecules that weren’t feasible until now. We work at the intersection of DevOps, MLOps, and Computational Biology. We scale ML inference on AWS for hundreds of GPUs and deploy a wide range of ML models for customers, navigating between Docker containers, Colab notebooks, bash scripts, slurm jobs, and more.

Tandem is reimagining the employer-employee relationship by making employer-sponsored training accessible to any employer with the imperative to grow.

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. Our core product listens in to the patient-clinician interaction to generate medical records, allowing clinicians to save 5-10 minutes per patient. We’ve recently raised a large seed round and are expanding our Stockholm team with exceptional engineers.

TandemAI is an advanced technology company dedicated to reinventing drug discovery infrastructure. The company integrates proprietary AI-driven, high-performance computation with its efficient, large-scale in-house wet lab operations to deliver a turnkey drug discovery solution.

We're building a fully automated agentic platform to help the construction industry optimize takeoffs, make better design decisions and reduce carbon emissions related to construction materials.

Tangled is the next-generation social coding platform. We offer git repository hosting, stacked PRs, Nix-based CI and more. We just raised our €3.8M ($4.5M) seed round to build foundational infrastructure for the future of open source. Some of the things we’re working on: a fully revamped CI (spindle v2!) built on micro VMs to allow for faster builds and more choice of build environments; protocol-level improvements across the board that’ll unlock nifty things like repo migrations across knots, organizations, and more; a customizable “mission control” dashboard for your active PRs, issues, and anything else you might want to track; a migration tool to help you move off GitHub; all things search: code search, repo search, etc.; platform and infrastructure performance improvements & more global presence; Tangled CLI! We’re prioritizing hiring for CI infrastructure, so strong distributed systems experience, Go, Firecracker/virtualization, etc. are what we’re looking for. If this sounds interesting, send us an email to team@!
