Remote Android Jobs in Toronto, ON (NOW HIRING)

BIMM is booming, so we're looking for an iOS-first Senior Mobile Developer with hands-on Swift/SwiftUI experience 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.

Who we are

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 of automotive, financial, telco and retail.

We are creative realists, which means our ideas and solutions are grounded in the realities of our clients' business. We believe big ideas are nothing without big results (and flawless execution); high-performing agencies deliver high-performing campaigns, products, and experiences; and the best solutions happen when we collaborate with clients as partners.

This is an existing vacancy, not a made-up role — this one's already got a desk waiting.

Who we're looking for

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.

You are a team player who can fly solo when needed. Although you have the full support of your teammates, you are able to lead the research and solution of complex problems. 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. Ultimately you will grow into leading agentic practice for mobile development.

You've learned about agentic systems and autonomous agents, maybe ran some in production or experimented with them a bit, and are excited to keep exploring how they can support the development of production-grade native mobile applications.

"Initiative" is your middle name and you don't give us a chance to chase you. We are on the hunt for people who have an innovative mindset (you still dream of that moonshot project but are currently working on your side-gig)! Is this you?

Responsibilities

Core Engineering

• Build a healthy, collaborative, and inclusive engineering environment.
• Communicate clearly with technical and non-technical stakeholders.
• Ensure manual and agentic generated code is production grade, respects design guidelines and is performant across devices and all supported screen sizes
• Work closely with Product, Design, QA, and back-end teams.
• Stay current with new mobile capabilities and use them when they add value.

AI Engineering

• Contribute to growing the Agentic practice for Mobile streams.
• 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.
• Define strict input/output contracts for MCP tools and agent skills using typed schemas; ensure tools handle edge cases, surface structured errors, and never return ambiguous output that an LLM must interpret.
• 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

Requirements

• 5+ years of mobile engineering experience, including lead ownership and responsibilities in an agile environment.
• Experience with iOS development using Swift, iOS SDK, SwiftUI.
• Experience with AI coding agents such as GitHub Copilot.
• Understanding mobile design patterns such as MVVM, MVP, MVI, MVC, or VIPER.
• Knowledge of iOS provisioning, app lifecycle, and release workflows.
• Awareness of unit testing and automation frameworks such as XCTest, XCUITest, Mokkery, Espresso, or Robolectric.
• Experience with accessibility standards, ideally WCAG 2.2 (desirable).
• Experience with offline storage, threading, and performance tuning.
• Experience with CI and CD practices for mobile applications, including GitHub Actions.
• 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.
• Strong teamwork, communication, and mentoring skills.

Nice to have

• 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 Jetpack Compose.
• Hands-on experience with prompt engineering: structured prompts, few-shot examples, schema enforcement, and output format constraints
• Experience with RAG (Retrieval-Augmented Generation), function calling, and deterministic routing within LLM-powered systems
• Hands-on experience with LLM structured output patterns: function/tool calling
• 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 prompt caching, semantic routing, or output memoization strategies to reduce non-determinism at scale.
• Ability to instrument LLM calls with structured traces (input, output, latency, token count, tool calls invoked) using frameworks like LangSmith, OpenTelemetry, or custom logging; can define SLOs for agent task success rates
• Experience with Kotlin Multiplatform.
• Familiarity with RESTful APIs to connect to applications to back-end services.

Even if you don't meet all of the above requirements, we still encourage you to apply!
