Become part of a senior team building a high-impact cybersecurity analytics platform used by global enterprises
 

Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries. 

About the Product

You’ll work on a cloud-native cybersecurity analytics platform used by Fortune-500 companies and global enterprises to understand and strengthen their security posture. It processes massive datasets, models attack paths, and uses AI-driven, graph-based analytics to surface the risks that truly matter.
The product is scaling fast, expanding to the SMB market across 32 European countries, and backed by a $100M+ growth investment round.

About the Role

We’re forming a new engineering team and looking for a Senior Python Engineer.

You’ll be part of a group of senior engineers, driving architecture decisions, and staying deeply involved in debugging and performance optimization. You’ll participate in the design and development of new features end-to-end, working on a system built for scale, accuracy, and real-world security impact.

The role requires close collaboration with product and engineering teams to translate complex technical challenges into clean, reliable solutions.

Why This Role Stands Out

✔ High-impact product used by major enterprises, built on real attack modeling and risk quantification
✔ Deep technical challenges - large-scale pipelines, distributed computation, graph modeling, real-time correlation
✔ Modern tech stack - Python, AWS, microservices, PostgreSQL, Redis, Docker, Kubernetes
✔ Become part of a high-bar team: 3 Senior Python + 1 Senior Angular engineers
✔ Backed by $100M+ investment and expanding across Europe
✔ Remote-first with strong support and competitive compensation

• We offer a highly competitive package with yearly performance and compensation reviews.

The Platform team is responsible for managing critical services that are essential to the success and sustainability of our organization. In simple terms, we handle transactional
communication send-outs to our customers via email, SMS, and push notifications. These services demand attention to detail, proactive maintenance, and swift response times to ensure
seamless operations.

Our recent high-priority initiatives include re-architecture/platform modernization, high availability and internationalization efforts; these are vital for our organization's growth and competitiveness in the market. These initiatives require dedicated expertise and resources to execute efficiently and effectively.

The team is looking for a Sr Software Engineer with the following requirements:

• Experience: 5+ years designing, developing, and launching backend systems at scale using Python. Kotlin experience is a nice-to-have.

About DualEntry

Founded in 2024, DualEntry is one of NYC’s fastest-growing AI startups.

DualEntry is changing the future of finance. Our AI-native ERP lets teams achieve more in less time. $5M-ARR businesses and NYSE-listed companies trust DualEntry to automate away busywork and fuel their growth with powerful reporting and insights. We’re making the one-person finance team a reality and putting the pain of legacy ERPs from the 1990s in the past.

We operate with urgency and ownership. We move fast.

Why This Role Matters Now

Since launching 18 months ago, we’ve raised $100M with backing from Lightspeed, Khosla, and Google Ventures. We got there by moving incredibly fast and hiring the best and brightest talent. To accelerate that momentum, we’re growing our team. Come and join us at one of NYC’s fastest-growing startups and have an impact on our product from day one.

This is an intense, hands-on role with full ownership.

You’ll be joining at an early and defining moment. Your work will directly shape our product, customers, and trajectory.

You’ll architect features and systems end-to-end at an incredible pace.

This is an opportunity to own critical infrastructure at the early stage of a category-defining AI company. Build the first, true AI accounting product with your own hands - alongside our elite team.

Where You’ll Create Impact

• Design and build core backend systems using Python
• Build APIs, services, and infrastructure that handle real-time, business-critical, and complex accounting logic

What Sets You Up for Success

• 5+ years of experience in backend engineering
• Deep experience with complex business logic products
• Bonus: expertise in Python and modern frameworks (FastAPI, Flask, or Django)
• Experience deploying on AWS (or similar cloud infrastructure)
• Strong database skills: PostgreSQL, SQL, ORMs, migrations, schema design
• Experience building and testing robust APIs
• Solid understanding of software lifecycle, CI/CD, and production-readiness
• Ability to manage complex systems with evolving requirements
• Fluent in English (C1+) with strong written and verbal communication

How You Operate

• Pragmatic: You like to move forward and make decisions based on reality (not theory). We don't debate if Cassandra has the most theoretical scalability -- we use Postgres until it breaks
• Hard working: 'You can work long, hard, or smart, but [here] you can't choose two out of three" - Jeff Bezos. We wrote this job post during the weekend
• Curious: You love to learn, are highly curious about new frameworks and solutions to engineering problems
• Fast-moving – You deploy daily, iterate quickly, and never wait for permission

Why You’ll Thrive Here

• Significant equity ownership in one of the top AI companies in the world
• You’re joining early and will grow with DualEntry
• Your feedback shapes the product directly
• High-speed culture
• High-trust environment with high expectations
• Ambitious mission

Compensation & Benefits

• Base salary: $100K–$175K USD
• Equity: ~$50K+ USD
