Head of Quantitative

B2B Financial Services Technology | Global Scale | Sydney (Hybrid)

• Greenfield opportunity to define a global quantitative capability

• Direct influence on product strategy and international expansion

• Work with sophisticated institutional clients at scale

A high-growth B2B financial services technology company is appointing a Head of Quantitative in a newly created role to build and lead its next-generation modelling capability.

Operating at the intersection of wealth management, actuarial science and enterprise software, this business partners with tier-one financial institutions across Australia, the UK and Europe to modernise how financial advice is delivered at scale.

This is a rare opportunity to architect stochastic modelling frameworks from first principles, while building and leading a world-class quantitative function with global reach.

The opportunity

The business is at a pivotal inflection point and is poised for continued market traction.

Having successfully deployed deterministic advice models at institutional scale, the next phase of growth requires the introduction of sophisticated stochastic modelling to unlock new markets, new products and materially improved customer outcomes.

As Head of Quantitative, you will:

• Define the quantitative strategy

• Lead the technical uplift to stochastic modelling

• Build and scale a high-performing team

• Act as the ultimate authority on model risk, integrity and regulatory alignment

This is a genuine player–coach role, with significant hands-on technical ownership.

What you’ll be responsible for

• Architect and deliver stochastic modelling frameworks (Monte Carlo, scenario generation, multi-goal optimisation)

• Lead the transition from deterministic Excel-based models to scalable calculation engines

• Translate complex regulatory and advice policy requirements into robust quantitative logic

• Build, mentor and scale a quantitative team across Australia and global markets

• Partner closely with Product and Engineering to productionise models at scale

• Engage directly with tier-one institutional clients, actuarial teams and regulators

• Own quantitative governance, validation and model risk standards globally

What it will take to make an impact

• Deep expertise in stochastic / actuarial / quantitative modelling

• Strong hands-on background in tools such as Excel, Python or actuarial modelling platforms

• Experience operating in regulated financial services environments (wealth, retirement, insurance or advice technology)

• Proven ability to lead technical teams while remaining hands-on

• Confidence engaging with C-level stakeholders, institutional clients and regulators

• Comfort operating in ambiguity within a high-growth, product-led business

• Advanced qualifications in Actuarial Science, Mathematics, Statistics or a related quantitative field are highly regarded.

If you’re motivated by complex problems, real-world impact and global scale, this is a rare leadership opportunity.  Call Michelle Rubinstein at The Onset on 0413 463 043 for a confidential discussion or apply online.

Senior Finance Leader (Future CFO Pathway)

Fintech  | Sydney | Up to $250k plus super

A rare opportunity for a commercially minded finance leader who wants to step into a high-impact role with genuine CFO trajectory.

We are partnering with a high-growth fintech whose cloud-based platform is used by financial institutions globally. The business is scaling rapidly and winning against their competitors.

As the business continues to expand its footprint, this is a newly created role for a finance leader who wants to play a pivotal part in shaping their financial strategy and infrastructure.

Working closely with the Exec leadership team, this role sits at the centre of the organisation and will be responsible for financial management, reporting and strategic financial planning for the group.

For the right person, this represents a clear pathway toward a future CFO role as the company continues its expansion.

The Opportunity

This is a broad and influential role where you will combine technical financial leadership with commercial insight, partnering closely with executive leadership and the board.

You will lead the financial management of the business while helping build the financial infrastructure required for a rapidly scaling fintech.

Key responsibilities include:

• Leading the financial planning and reporting function for the consolidated group

• Preparing monthly management and board reporting

• Managing budgets, forecasting and performance analysis

• Ensuring strong financial controls, governance and reporting processes

• Overseeing cash management and banking relationships

• Preparing statutory accounts and coordinating external auditors and advisers

• Managing tax compliance, including R&D claims

• Supporting fundraising activities and financial due diligence

• Delivering commercial analysis and financial modelling to support growth decisions

• Developing scalable financial systems, reporting frameworks, and operational processes

• Mentoring and leading a small, growing team

• Acting as a trusted adviser to senior leadership

What Success Looks Like

• Senior leadership and the board view you as a trusted financial partner with sound judgement

• The business operates with robust financial controls and zero surprises

• Financial reporting provides accurate and clear insight to drive commercial decision making

• The finance function evolves to support growth and increasing complexity

About You

You are a high-performing finance leader who enjoys operating in dynamic, growth environments and wants the opportunity to step toward a CFO role.

You are likely to bring:

• Significant experience in financial management or financial controller roles

• Exposure to high-growth technology, fintech SaaS, or financial services environments

• Strong experience with board reporting, forecasting and financial planning

• Proven ability to balance hands-on financial management with commercial thinking

• Experience working with external auditors, tax advisers and regulatory environments

• Strong stakeholder management skills with the confidence to engage at executive and board level

Experience supporting capital raising, investor reporting or international operations will be highly regarded.

Why This Role Stands Out

• Newly created with a clear pathway toward a future CFO role

• Exposure to global operations 

• Opportunity to shape the finance function of a scaling business

• Direct engagement with senior leadership and board

• Work at the forefront of innovation 

If you’re an ambitious finance leader who wants real strategic influence and a pathway to CFO, call Michelle Rubinstein at The Onset for a confidential discussion or apply online.

Senior / Staff Backend Engineers - Build Platforms at the Intersection of Embedded Systems, Data & AI

I’m currently partnering with a small but ambitious Australian technology company that is quietly building a platform sitting at the intersection of embedded products, data, and emerging AI capabilities. 

The engineering organisation is structured around three key initiatives. The core platform team focuses on embedded product infrastructure, which is where most engineers initially join and build a deep understanding of the systems. Alongside this, the company is developing a new AI-driven initiative, with their first product expected to launch later this year. The longer-term ambition is to evolve into a generative-AI-native platform, with engineers gradually gaining exposure to this work as the roadmap unfolds.

From an engineering perspective, the team is looking for Senior or Staff-level backend engineers who think beyond a single language or framework. They are particularly interested in polyglot engineers who have built and operated production systems across multiple stacks and enjoy solving complex problems rather than simply implementing tickets.

The environment is highly collaborative and product-focused. Engineers work closely with product, design, and data teams to shape solutions from early problem definition through to delivery. Strong engineers here are the kind who ask thoughtful questions, challenge assumptions, and bring others along on the journey rather than working in isolation.

Technically, the platform is largely Python-based (Django / Flask / FastAPI) with cloud infrastructure in AWS, modern CI/CD practices, and architectures built around microservices and event-driven systems. Engineers are expected to take ownership of systems end-to-end - from designing scalable services and reviewing code across the squad, to improving platform health through monitoring, logging, and infrastructure automation.

Because the company operates in a highly regulated industry, engineers must also enjoy working within real-world constraints. This means designing systems that are not only scalable and elegant, but also secure, resilient, and compliant.

The team itself is distributed, with a strong engineering presence in Sydney but openness to outstanding engineers across Melbourne or Newcastle provided collaboration and communication remain strong.

This role tends to resonate with engineers who:

• Enjoy owning systems end-to-end, not just contributing small components
• Are curious problem solvers who ask the right questions before jumping to solutions
• Have experience working across multiple languages or architectures
• Care about platform quality, engineering standards, and mentoring others
• Want exposure to AI-driven product development while still working on meaningful platform problems

It’s a rare opportunity to join a small, high-calibre engineering team early, shape the technical platform, and work on problems that sit across backend engineering, distributed systems, and the next generation of AI-enabled products.
