Lead iOS Developer

with hands‑on Swift/SwiftUI experience and working knowledge of Android/Kotlin, and a strong interest in agentic AI systems that generate and support production‑grade native mobile applications.

Local candidates (GTHA) will be asked to join us at BIMM HQ (Distillery District) 2 days per week. We are open to remote candidates across Canada – you will be required to work on EST hours.

BIMM is a Toronto‑based agency that lives at the intersection of data, technology, and creativity to provide clients with high‑performing campaigns and digital products that shape connected customer experiences. We’ve helped our clients implement fully integrated CRM customer journeys, built robust digital experiences, and created national loyalty programs with decades of experience in sectors such as automotive, financial, telco, and retail.

We are creative realists, which means our ideas and solutions are grounded in the realities of our clients’ business. You have leveraged modern mobile tools and frameworks (Swift/SwiftUI, Kotlin, Jetpack Compose, and Kotlin Multiplatform) to architect and deliver iOS and Android applications from the ground up.

At the same time, you know when to ask for help and don’t let pride or ego get in the way, because after all, you are part of a team. This role will directly support our client Audi and have the opportunity to shape the development of their digital platform. We are on the hunt for people who have an creative mindset (you still dream of that moonshot project but are currently working on your side‑gig). Communicate clearly with technical and non‑technical stakeholders.

AI Engineering

Develop agentic systems that reliably generate production‑grade code using Swift, SwiftUI, Kotlin, and related platform tools.

Build and maintain automated evaluation pipelines (evals)



for agent and skill outputs including LLM‑as‑judge scoring, regression test suites, and golden dataset validation so that prompt and model changes are measurable before they ship.

Own the prompt engineering lifecycle for assigned tools and skills version‑controlled prompt templates, parametric input injection, and structured system/user role separation ensuring prompts are testable, reproducible, and free of implicit context drift.

Contribute to the team's MCP tooling catalog implement, test, and document MCP‑compatible integrations.

5+ years of mobile engineering experience, including lead ownership and responsibilities in an agile environment.

Experience with AI coding agents such as GitHub Copilot.

Awareness of unit testing and automation frameworks such as XCTest, XCUITest, Mokkery, Espresso, or Robolectric.

Experience with offline storage, threading, and performance tuning.

Strong understanding of Git‑based version control and GitHub workflows.

Solid knowledge of cloud messaging and push notifications.

Ability to translate business requirements into clear technical plans.

Experience designing and building agentic workflows – systems that plan, decompose tasks, execute, self‑validate, and iterate on failures.

Experience with Kotlin and Android fundamentals.

Familiarity with LLM evaluation approaches: building golden test sets, LLM‑as‑judge pipelines,



and prompt regression testing; ability to quantify output quality with measurable metrics rather than vibes.

Experience building or consuming agentic workflows multi‑step tool chains, state machine‑based agents, or orchestration frameworks (LangGraph, LangChain, AutoGen, or custom) with an emphasis on deterministic routing and graceful failure handling.

Demonstrated experience defining and rolling out engineering standards at a team or org level (coding conventions, PR workflows, testing mandates, API contracts).

Track record of driving AI tool adoption within an engineering team — not just using the tools but creating the onboarding, guidance, and culture around them.

Experience with Kotlin Multiplatform.

Spend your birthday any way you’d like, as long as it’s not at the office. Extra day off to enjoy every summer holiday and a week‑long end‑of‑year break.

Benefits: We offer a comprehensive health & dental benefits plan with an Employee Assistance Program. BIMMers are also given extra money to put towards wellness or health‑related needs. A little BIMM bonus to build your bank.

Our social committee plans BIMM bashes, Tasty Thursdays and quarterly outings like candle making workshops, board game nights, Jays games and cooking classes. Our summer and holiday parties are quite memorable as well! We observe a hybrid working model in our beautiful dog‑friendly office located in the Distillery District, stuffed with snacks.

Growth: BIMM is part of kyu collective which gives our employees access to the network’s resources, training, offices, and more. We also prioritize your personal and professional development with opportunities like on‑site Lunch n’ Learns, conferences and online courses. 140,000 CAD – $160,000 CAD.
