I have emailed you.

SalesJack | Solutions Engineer | Toronto, ON, Canada | HYBRID | FULL-TIME

SalesJack is a sales software platform (CRM, Prospecting Service) for independent businesses in the construction supply industry. We are growing quickly and profitably. Our engineering team is growing in Canada.

As a Solutions Engineer at SalesJack, you'll own the technical side of bringing new customers live and keeping them successful. Every implementation involves ERP integration, product category mapping, permit source configuration, data migration, and on-site training — and you'll be the person who makes all of that happen. Post-launch, you'll handle customizations: new reports, routing rules, data transformations, and one-off integrations. You'll work closely with founders, engineers, and the dealers using our product every day. We highly value a startup mentality—taking initiative, moving quickly, and iterating solutions based on real customer feedback.

We are looking for:

- 2+ years in a Solutions Engineering, Implementation Engineering, Data Engineering, or similarly hands-on technical customer-facing role

- Strong SQL — comfortable writing non-trivial queries against Snowflake, Postgres, or similar warehouses

- Comfort with REST APIs, auth flows, pagination, rate limits, and debugging flaky endpoints

- Familiarity with (or strong interest in) construction supply ERPs such as BisTrack, DMSi Agility, or ECI Spruce

- Some travel may be required to customer sites in the US

Our hiring process will be:

1. Initial call with our founding team to briefly discuss your background and introduce SalesJack ~30mins

2. Technical Exercise: SQL, integration design, and a customer scenario walkthrough ~1.5 hours

3. Cultural fit call with one of our founders ~30mins

4. Offer

Stealth Startup | Founding Engineer | NYC (in-person 5x/week) | Full-Time

The mission We’re building a best-in-class multi-modal AI agent product (voice + SMS + email) with the potential to disrupt deeply entrenched software businesses and unify a fragmented industry. We’re a tiny team with real traction pre-product, moving fast, and we care obsessively about craft.

Why this role This is a founding engineering seat: you’ll be an early builder shaping the product, architecture, and quality bar from day one. In the first 3–6 months, the role is highly IC-focused. As we scale (including our first in-person hub/site and new hires), this role has optionality (i.e., growing into a leadership role or staying on the IC track and owning the engineering roadmap) for the right person.

What you’ll do

Build real-time systems for voice (streaming audio, low latency, turn-taking), SMS, and email automation with robust state + memory. Design the foundation: architecture, data model, reliability, observability, deployment, and developer velocity. Set the quality bar: clean code, pragmatic abstractions, testing strategy, “don’t break prod,” and thoughtful product UX. Partner closely with the co-founders on product decisions. You’ll have real influence over what we build and how it feels + how it's designed.

What we’re looking for You should be able to work anywhere in the stack (frontend, backend, infra, integrations) and you know how to make smart tradeoffs.

Strong product sense: you’re obsessive about confusing UI and you want to make workflows feel magical. Systems thinking: you can design for latency, reliability, and iteration speed (especially for real-time voice + agent state). High ownership: you run toward ambiguity, unblock yourself, and care deeply about outcomes. Startup mindset: high-risk/high-reward energy, low ego, high pace.

Bonus points:

Experience with agentic systems: LLM orchestration, tool calling, RAG, evals, prompt/versioning, guardrails. Voice/telephony or streaming experience (WebSockets/WebRTC, audio pipelines, turn detection). Messaging + deliverability experience (SMS workflows, email sending, compliance/opt-in, bounce handling). Familiarity with modern stacks (examples): TypeScript/Node, Python, React/Next.js, Postgres, Redis, queues, Docker, AWS/GCP, observability.

Founding AI, Data Science Lead (Possible Co-Founder Track) Pre-seed consumer health and wellness company. Product is live. IP track ready. Raising pre-seed this year. We're building proprietary intelligence on top of longitudinal biological and lifestyle data. Near-term infrastructure. Consumer company with AI infrastructure goals. What you'll do You'll be a visionary alongside the founder. Design and ship the models that power the product. Build the data pipelines, evaluation frameworks, and production infrastructure. Set the technical direction as the company grows. Who we're looking for A maker. Someone who dreams the future and then builds it. You design and you deploy. You work well with teams. Strong data science and AI engineering background. Experience with longitudinal data, time-series, or biometric signal. Medical and scientific rigor in how you think is ideal but not required.
