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

Steel is open-source browser infrastructure for AI agents and apps. We make it easy for developers to ship products that interact with the web - without spending 80% of their time on browser pools, proxies, CAPTCHAs, and session state. In 2025 we grew 50x: 6,000+ GitHub stars, dozens of paying customers, millions of sessions served monthly. Dedicated chromium runs on Firecracker VMs for sub-second cold starts.
Stack: TypeScript, React/Next.js, Node.js, AWS, Firecracker, Postgres, Redis. 4+ YOE for both roles.
--- Applied AI Engineer ---
Shape how AI agents interact with the web. Build open-source frameworks/demos on the Sessions API, run experiments on which models/prompts/harnesses actually work, build evals against real scenarios, and work with customers shipping agents to production. AI-native full-stack engineers with strong product sense.
--- Infrastructure Engineer ---
Design and operate the systems Steel runs on. Sample projects: VM snapshotting that restores full browser state in under a second, performance-tuning the Sessions API from kernel traces, orchestrating millions of sessions with sub-second cold starts. Distributed-systems experience, strong AWS/GCP and Linux/OS fundamentals. Rust is a plus.
Public referral bonus: $10,000 if your intro becomes a hire.

Simple Ventures is a Canadian venture studio that builds new companies from day zero - we source ideas, validate them with real users, build MVPs, and hand off to CEOs to scale the ones we bet on. We're backed by the founders and leaders of Wealthsimple, Shopify, Ada, MindBeacon, and TD.
We're hiring for two roles:
Founding AI Engineer - the technical backbone of the studio. You'll build internal tooling, prototype MVPs for new ventures, and partner with our portfolio companies on applied AI.
New Venture Lead (0→1) - you'll operate like a founder, sourcing venture ideas, running validation loops with real users, killing weak ideas quickly, and writing CEO-ready memos for the ones we decide to invest in.

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.
Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.
As our QA Engineer, you'll assist in improving the quality of Rinse's software, which services our customers, valets, vendors, and warehouse personnel. You'll be involved in the full project lifecycle, from idea through documentation and feedback. You'll also drive software quality through testing, collaboration, and documentation.
We're a tiny team tackling big problems, so our technical staff enjoys considerable autonomy, flexible schedules, and ambitious projects with clear and meaningful impact on our business.
This season, we're particularly interested in new grads or junior engineers, to round out the team. You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.

Psiphon is a VPN app used by millions of people to access the open internet in regions where it's restricted. Small team, software that matters.
We're building the next-gen client app in Flutter (iOS, Android, macOS, Windows) and need someone who can work across both iOS native and Flutter. Split is roughly 65% Flutter, 35% iOS native (Swift, StoreKit, entitlements, network extensions). You'll have mentorship from a senior iOS specialist for the deeper networking work.
Day to day: Feature development in Flutter, iOS platform integration (subscriptions, permissions, App Store), and occasionally going deep into network extensions and packet tunnel providers. Small team (~3-4 core devs), high ownership, low ceremony.
Looking for: Strong Swift experience beyond just UIKit/SwiftUI app dev, comfort with the iOS ecosystem (App Store process, provisioning, StoreKit), and willingness to context-switch between Swift and Dart in the same day. Flutter experience is a strong plus but not required if you pick up frameworks quickly.
